3. A species of orchids have a gene encoding either a dominant pink (P) or recessive white (p) flower color trait. If a heterozygous pink and white flower were crossed, what is the probability that the offspring have white flowers?​

Answers

The correct probability is indeed 0.25 or 25%.

When heterozygous pink (Pp) and white (pp) flowers are crossed, the Punnett square can be used to determine the probability of offspring having white flowers:

     |   P     p

---------------

 P  |  PP   Pp

---------------

 p  |  Pp   pp

From the Punnett square, we can see that there are four possible combinations of alleles for the offspring: PP, Pp, Pp, and pp.

Out of these four possibilities, only one combination (pp) corresponds to the white flower trait.

Therefore, the probability of an offspring having white flowers is 1 out of 4.

In terms of probability, this can be expressed as:

Probability of white flowers = Number of favorable outcomes / Total number of possible outcomes.

= 1 / 4

= 0.25

So, the correct probability is indeed 0.25 or 25%.

Assume the data is from a normally distributed population. 90% C.I. =

Answers

The 90% confidence interval for the mean body temperature of adults in the town is approximately (97.299, 98.529).

How to solve for the confidence interval

The given data points are:

97.1, 98.1, 98, 97.7, 97.4, 99.3, 96.8

Step 1: Calculate the sample mean (µ):

µ = (97.1 + 98.1 + 98 + 97.7 + 97.4 + 99.3 + 96.8) / 7 ≈ 97.914

sample standard deviation (s):

≈ 0.839

Step 3: Calculate the standard error (SE):

SE = s / sqrt(n)

≈ 0.839 / sqrt(7) ≈ 0.317

Step 4: Find the t-value for a 90% confidence interval with 6 degrees of freedom (n - 1 = 7 - 1 = 6).

Using a t-distribution table  we find that the t-value is approximately 1.943.

Step 5: Calculate the margin of error (ME):

ME = t-value * SE

≈ 1.943 * 0.317 ≈ 0.615

Step 6: Calculate the confidence interval:

Lower limit = µ - ME ≈ 97.914 - 0.615 ≈ 97.299

Upper limit = µ + ME ≈ 97.914 + 0.615 ≈ 98.529

So, the 90% confidence interval for the mean body temperature of adults in the town is approximately (97.299, 98.529).

Answers

x⁴ - 8x² + 17 is the function that represents the fog(x).

To find fog(x), we first need to find g(f(x)), which means we need to substitute the expression for f(x) into the expression for g(x):

g(f(x)) = g(x² - 4)

Now, we can substitute the expression for g(x) into the above expression:

g(f(x)) = (x² - 4)² + 1

Expanding the squared term, we get:

g(f(x)) = x⁴ - 8x² + 17

A sample of size =n78 is drawn from a normal population whose standard deviation is =σ5.1. The sample mean is =x47.95.

Answers

The 95% confidence interval for the population mean is (47.00, 48.90).

A sample of size n=78 is drawn from a normal population with a standard deviation of σ=5.1. The sample mean is x=47.95.

Using this information, we can estimate the population mean using the formula:

μ = x ± z*(σ/√n)

where μ is the population mean, x is the sample mean, z is the z-score for the desired level of confidence (e.g., 1.96 for a 95% confidence interval), σ is the population standard deviation, and n is the sample size.

Assuming a 95% confidence level, the z-score is 1.96. Plugging in the given values, we get:

μ = 47.95 ± 1.96*(5.1/√78)

Solving for the upper and lower bounds of the confidence interval, we get:

μ = 47.95 ± 0.95

So the 95% confidence interval for the population mean is (47.00, 48.90). This means that if we were to repeat this sampling process many times, we would expect the true population mean to fall within this interval 95% of the time.

Answers

The entire number is odd.

For any number n, the predecessor is n - 1 and the successor is n + 1.

We have,

To find the place value of the number in the thousand's place for the number obtained by adding 60 tens, 58 hundreds, and 685 ones, we can start by realizing that 60 tens are the same as 600, and 58 hundreds are the same as 5800.

Therefore, we have:

600 + 5800 + 685 = 7085

So the number is 7085.

The digit in the thousand's place is 0 since there is no digit in the thousand's place.

Therefore, the place value of the number in the thousand's place is 0.

To determine if the number is even or odd, we can look at the unit digit, which is 5.

Since 5 is an odd number,

The entire number is odd.

2.

The predecessor of a number is the number that comes before it, and the successor of a number is the number that comes after it.

To find the predecessor of a number, we subtract 1 from the number, and to find the successor, we add 1 to the number.

For example,

Let's say we want to find the predecessor and successor of the number 7.

The predecessor of 7 is 6, since 7 - 1 = 6.

The successor of 7 is 8, since 7 + 1 = 8.

In general,

For any number n, the predecessor is n - 1 and the successor is n + 1.

The total purchase is  $18.90.

We have,

A discount would reduce the cost of the purchase. A tax increases the cost of the purchase.

The first step is to determine the total cost of the items purchased.

Total cost = (cost of lb of cheese x lb bought) + (cost of sliced ham x lbs bought) + (cost of bread x loaves bought) + (cost of a bag of potato chips x number of bags bought) + (cost of one salsa container x number of containers bought)

(1.99 x 1/2) + (3 x 3.29) + (1.59 x 2) + (2 x $3) + (1.39 x 1) = $20.39

Since, the total cost is greater than $20 she qualifies for the 10% discount

Total cost after the discount = (1 - 0.1) x $20.39

0.9 x $20.39= $18.35

Cost after the tax = (1 + 0.03) x $18.35

The probability that Jess wins a Chess game is 0.4. What is the probability that Jess will win only the third game if she played Chess thrice? Round your answer to three decimal places.

Answers

The probability that Jess will win only the third game out of three games is 0.144, or 14.4%


To calculate the probability that Jess will win only the third game out of three games, we will use the concept of independent events. In this scenario, we have the following events:

1. Jess loses the first game.
2. Jess loses the second game.
3. Jess wins the third game.

Since the events are independent, we can calculate the probability of this specific sequence occurring by multiplying the probabilities of each individual event:

1. Probability of losing the first game: 1 - 0.4 = 0.6
2. Probability of losing the second game: 1 - 0.4 = 0.6
3. Probability of winning the third game: 0.4

Now, we multiply these probabilities together:

0.6 * 0.6 * 0.4 = 0.144

So, the probability that Jess will win only the third game out of three games is approximately 0.144, or 14.4% when rounded to three decimal places.

At some later time, the crew measures the angle of elevation from point B to be 4 degrees. Find the distance from point A to point B. Round your answer to the nearest foot if necessary.

Answers

The distance from point A to point B is approximately 920 feet.

How to find the distance from point A to point B

Let's call the distance from point A to point B as x.

From point A, the angle of elevation to the lighthouse's beacon-light is 8 degrees.

Using the tangent function to find the height of the lighthouse (h):

tan(8) = h/1083

h = 1083 tan(8) ≈ 157.6 feet

From point B, the angle of elevation to the lighthouse's beacon-light is 4 degrees.

Using the tangent function again to find the height of the lighthouse from point B (h'):

tan(4) = h'/(1083-x)

h' = (1083-x) tan(4) ≈ 78.6 - 0.07x

Since the height of the lighthouse should be the same from both points A and B, we can set h = h' and solve for x:

1083 tan(8) = (1083-x) tan(4)

x = 1083 - (157.6/tan(4)) ≈ 920 feet

Therefore, the distance from point A to point B is approximately 920 feet.

Tamara's tuition for her first year of college costs $8,240. Tamara received a scholarship that will

cover .25 of the cost. If Tamara has two years to save up the remaining amount, how much should she save each month in order to meet her
goal?

Answers

Answer:

Check Explanation

Step-by-step explanation:

The question is incomplete. But I can explain in a way that the full question can be easily solvable.

Note that the missing part of the question is percentage or fraction of the total college tuition cost that the scholarship covers.

For the sake of clarity, let us assume that the scholarship covers 60% of the total college tuition costs.

This means that Tamara still has to raise 40% of the total college tuition cost herself over the space of 2 years (24 months)

The total college tuition cost = $8240

Amount that Tamara still needs to raise = 40% × 8240 = $3296

She has to raise this amount over 2 years (24 months) on a monthly basis.

So, the amount she has to save monthly over 24 months = (3296/24) = $137.333

So, whatever the fraction or percentage of the total college tuition cost that the scholarship covers, just divide the rest of the college tuition cost after the scholarship has done its part (1 - fraction or 100% - percentage) by 24 months.

The answer is the amount that Tamara needs to save monthly.

The second option: It is given that the mode shows that Karl has 3 friends who live 3 blocks from him, but according to the given data set Karl has 3 friends who lives 2 blocks from him. Hence the mode is 2.

Hence, this option is incorrect.

The third option: It is given that the minimum distance from Karl's house to a friend's is 2 blocks, but according to the given data set the minimum distance from Karl's house to a friend's is 1 block.

Hence, this option is incorrect.

The fourth option:  It is given that the mean distance to his friend's houses is in between 2 and 3 blocks.

We will find the mean for the given data set.

⇒ Mean = (Sum of all the data points) / (Total number of data points)

⇒ Mean = (1 + 2 + 5 + 3 + 2 + 2 + 5 + 3)/8

⇒ Mean = 23/8

⇒ Mean = 2.875

∴ The mean distance from Karl to his friend's houses is 2.875 which is in between 2 and 3.

Hence, this option is correct.

Therefore, the fourth option which says the mean distance between Karl and his friend's houses is in between 2 and 3 is correct.

Answer:

x=335/336

Step-by-step explanation:

First of all, we open the parentheses. 17x+14 1/2-2 3/7+7x=36. Then, we subtract the mixed fractions. 14 1/2-2 3/7=12 1/14. Then, we add the x's. 17x+7x=24x. What we get is 12 1/14+24x=36. We have to subtract 12 1/14 on both sides. 24x=23 13/14. To find x, we do 23 13/14 divided by 24=335/336. x=335/336

Hello!

3^5 x 3^2 = 3^7

x=7

Answer:

x = 7

Step-by-step explanation:

Product of powers rule:

[tex] a^m \times a^n = a^{m + n} [/tex]

When you multiply two powers with the same base, add the exponents.

[tex] 3^5 \times 3^2 = 3^x [/tex]

Apply the rule above to the left side.

[tex] 3^{5 + 2} = 3^x [/tex]

[tex] 3^7 = 3^x [/tex]

[tex] x = 7 [/tex]

A bead is selected at random from a bowl. The probability of selecting a bead with two holes is 0.5. The probability of selecting a bead that is both red and has two holes is 0.2. What is the probability of selecting a red bead given the bead has two holes? Enter your answer as a decimal in the box.

Answers

Answer:

0.4

Step-by-step explanation:

Let A be the event of selecting a bead with two holes and B be the event of selecting a red bead. We are given P(A) = 0.5 and P(A and B) = 0.2. We need to find P(B|A), the probability of selecting a red bead given the bead has two holes.

By definition of conditional probability, we have:

P(B|A) = P(A and B) / P(A)

Substituting the given values, we get:

P(B|A) = 0.2 / 0.5

Simplifying, we get:

P(B|A) = 0.4

Therefore, the probability of selecting a red bead given the bead has two holes is 0.4.

Answer: 0.2.

The inverse function of f(x) is given as follows:

[tex]f^{-1}(x) = \sqrt{x}[/tex]

How to obtain the inverse function?

The function f(x) graphed in this problem is given as follows:

f(x) = x².

Using the notation y = f(x), we have that:

y = x².

To obtain the inverse, first we exchange y and x, hence:

x = y².

Finally, we must isolate the variable y, hence:

[tex]y = \pm \sqrt{x}[/tex]

[tex]y = \sqrt{x}[/tex] -> we take only the positive and the domain is the non-negative numbers.

Hence the inverse function is:

[tex]f^{-1}(x) = \sqrt{x}[/tex]
