Rachel has a bag containing 3 red marbles, 5 purple marbles, and 10 blue marbles.
What is the probability that she will pull a purple marble out of the bag? What is the
complement?

Answers

Answer 1

Answer:

5/18, 13/18

Step-by-step explanation:

The basic probability of anything is Specific Outcome / Total Outcomes

The specific outcome here is pulling a purple marble. We see there are 5 purple marbles therefore there are 5 ways to get them. The total outcomes are the total number of marbles which is 18. Therefore, the answer is 5/18

The complement of a probability is 1 minus the original probability, so, it would be 1 - 5/18 here getting us 13/18 as the answer.

If f(x) is an exponential function where f(2.5)=26 and f(6.5)=81, then find the value of f(12), to the nearest hundredth.

Answers

Given:

f(x) is an exponential function.

[tex]f(2.5)=26[/tex]

[tex]f(6.5)=81[/tex]

To find:

The value of f(12), to the nearest hundredth.

Solution:

The general exponential function is

[tex]f(x)=ab^x[/tex]

For, x=2.5,

[tex]f(2.5)=ab^{2.5}[/tex]

[tex]26=ab^{2.5}[/tex]          ...(i)

For, x=6.5,

[tex]f(6.5)=ab^{6.5}[/tex]

[tex]81=ab^{6.5}[/tex]          ...(ii)

Divide (ii) by (i).

[tex]\dfrac{81}{26}=\dfrac{ab^{6.5}}{ab^{2.5}}[/tex]

[tex]\dfrac{81}{26}=b^4[/tex]

Taking 4th root on both sides, we get

[tex]\sqrt[4]{\dfrac{81}{26}}=b[/tex]

[tex]b\approx 1.32855[/tex]

Putting b=1.32855 in (i), we get

[tex]26=a(1.32855)^{2.5}[/tex]

[tex]26=a(2.03444)[/tex]

[tex]\dfrac{26}{2.03444}=a[/tex]

[tex]a\approx 12.7799[/tex]

Now, the required function is

[tex]f(x)=12.7799(1.32855)^x[/tex]

Putting x=12, we get

[tex]f(12)=12.7799(1.32855)^{12}[/tex]

[tex]f(12)=386.4224[/tex]

[tex]f(12)\approx 386.422[/tex]

Therefore, the value of f(12) is 386.422.

or

[tex]9.635 =9+0.6+0.03+0.005[/tex]

We can write it using the powers of ten.

[tex]9.635 =9.635 \times 10^0[/tex]

10⁰ is equal to 1.

Farah predicts that the average text messages sent by her family will be 2042 messages each of the last 6 months in 2019. The number of text messages used during 5 of those months were 2800, 2481, 2105, 1975, 2732. How many text messages must be sent during the sixth month for her prediction to be true?

Answers

Answer:

159 text messages

Step-by-step explanation:

Given that:

Predicted average = 2042

Number of months = 6

Number of texts for each of last 5 months :

Let number of text that must be sent in the sixth month = x

Predicted Average = (sum of texts / Number of months)

2042 = (2800 + 2481 + 2105 + 1975 + 2732 + x) / 6

2042 = (12093 + x) / 6

Cross multiply :

6 * 2042 = 12093 + x

12252 = 12093 + x

x = 12252 - 12093

x = 159

Mrs. William's class is doing coin drive to raise money for a charity. Students have brought a total of 64 quarters and nickels . The students have raised a total of $ 12. Find the number of quarters Mrs. William's class has collected .

Answers

q=quarter
n=nickel
q+n= 64
.25q+.05n= 12
Times 100
25q+5n= 1200
-25(q+n=64)
-25q-25n= -1600

25q+5n = 1200
-25q-25n = -1600
-20n = -400
Divide -20 on both sides
n=20
There are 20 nickels

q+n= 64
q+20=64
Subtract 20 on both sides
q=44
There are 44 quarters

Check work
.25(44) + .05(20) = 12

A frame designer is making a triangular frame. She has two sides of length 18 inches and 27 inches. What are the possible lengths (in whole inches) for the third side?

Answers

Answer:

Therefore, the possible lengths (in whole inches) for the third side is

9 inches < x < 45 inches

Step-by-step explanation:

For the above question, we have a rule, the sum of the length of any two sides of the triangle must be greater than the length of the third side.

Hence:

She has two sides of length 18 inches and 27 inches

Let the third side = x

Hence:

a) 18 + 27 > x

45 > x

b) 18 + x > 27

x > 27 - 18

x > 9

Therefore, the possible lengths (in whole inches) for the third side is

9 inches < x < 45 inches

Answer:

0.12

Step-by-step explanation:

Probability is defined as the number of possible outcomes divided by the total outcome.

Given that 15% of the students drive to school and of  the students that drive to school, 80% are seniors then the probability a randomly selected  student drives to school and is a senior P(D&S)

= 15% * 80%

= 15/100 * 80/100

= 0.12

The 4th option

This question is based on the concept of probability. Therefore the correct option is (D), that is 0.12 is the probability a randomly selected  student drives to school and is a senior.

Given:

At a large high school, 15% of the students drive to school. Of the students that drive to school, 80% are seniors.

We have to calculated the probability a randomly selected  student drives to school and is a senior.

By the definition of probability,

Probability is  branch of mathematics, and it is defined as the number of possible outcomes divided by the total outcome.

Given that, 15% of the students drive to school and of  the students that drive to school, 80% are seniors.

Hence, the probability a randomly selected student drives to school and is a senior is ,

[tex]=\dfrac{15}{100} \times \dfrac{80}{100}\\\\= 0.15 \times 0.8\\\\= 0.12[/tex]

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

There are 75 pieces of candy in a 15 oz bag.

So, Per ounce the amount of candy

= 75/ 15

= 5

Hence, In 1 ounce there are 5 piece of Candy.
