Answer:
0.43
Step-by-step explanation:
Formatting the Given data into a probability distribution table :
X : ____ 0 __ 1 ___ 2 ____ 3 _____ 4 ____ 5
P(x) : _0.09_0.11 _ 0.24 _0.21 ___ 0.17 __ 0.05
Probability of making 3 or more mistakes :
P(x ≥ 3) = P(x = 3) + P(x = 4) + P(x = 5)
P(x ≥ 3) = 0.21 + 0.17 + 0.05
P(x ≥ 3) = 0.43

Find three consecutive integers such that the sum of twice the second integer and 4 times the third integer is two less than seven times the first integer.
Answer:
12,13 and 14
Step-by-step explanation:
Let the three consecutive integers be n, n+1 and n+2
ATQ,
The sum of twice the second integer and 4 times the third integer is two less than seven times the first integer.
[2(n+1)+4(n+2)] = 7n-2
or
2n+2+4n+8=7n-2
Taking like terms together,
6n-7n = -2-8-2
n = 12
So,
First integer = 12
Second integer = 12+1 = 13
Third integer = 12+2 = 14
Hence, three consecutive integers are 12,13 and 14.

James and Bethany Morrison are celebrating their 10th anniversary by having a reception at a local reception hall. They have budgeted $3500 for the reception. If the reception hall charges a $50 cleanup fee plus $34 per person find the greatest number of people that they may invite and still have within their budget.
Answer: See Below
Step-by-step explanation:
Create the equation:
$34 times the number of people plus the $50 cleaning fee has to be less than or equal to $3500
Or
34p + 50 <= 3500
34p <= 3450
p <= 101.470588....
We can have a part of a person attending the reception so we have to drop the remainder/decimal. Therefore the most amount of people that can attend the party and stay within budget is 101.

A large sleep study involving over 5000 American teenagers examined how many hours the participants slept on the weekend. The nightly sleep times were distinctly non-normal with a mean of 10 hours and a standard deviation of 2 hours. Suppose we take a random sample of 100 nightly sleep times from this population. We can assume that the times in the sample are independent. What is the probability that the mean of these 100 sleep times is farther than 0.4 hours away from the population mean?
a) 0455
b) .02
c) 1
d) .02275
Answer:
.05
Step-by-step explanation:
Khan
Using the normal distribution and the central limit theorem, it is found that the probability that the mean of these 100 sleep times is farther than 0.4 hours away from the population mean is:
a) 0.0455Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X. By the Central Limit Theorem, the sampling distribution of sample means of size n, as long as n > 30, is approximately normal and has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
Mean of 10 hours, hence [tex]\mu = 10[/tex].Standard deviation of 2 hours, hence [tex]\sigma = 2[/tex].Sample of 100, hence [tex]n = 100, s = \frac{2}{\sqrt{100}} = 0.2[/tex].We want the probability that the mean is farther than 0.4 hours away from the population mean, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{0.4}{s}[/tex]
[tex]Z = \frac{0.4}{0.2}[/tex]
[tex]Z = 2[/tex]
The probability is P(|Z| > 2), which is 2 multiplied by the p-value of Z = -2.
Z = -2 has a p-value of 0.0275.2 x 0.0275 = 0.0455Hence, option A is correct.

Anna, Bertie and Carl share £135 in the ratio 5 : 4 : 6.
How much does Carl get?
Answer:
Anna gets £45, Bertie gets £36 and Carl gets £54
Step-by-step explanation:
→ Add the ratios together
5 + 4 + 6 = 15
→ Divide the amount by the total of ratios
135 ÷ 15 = 9
→ Multiply 9 by each part of the ratio
Anna = 5 × 9 = £45
Bertie = 4 × 9 = £36
Carl = 6 × 9 = £54
Evaluate the expression.

A bakery offers a sale price of $2.60 for 4 muffins. What is the price per dozen?
Answer:
31.2
Step-by-step explanation:
2.60 times 4 is 10.4.
4 times 3 is 12
10.4 times 3 is 31.2
Answer:
Hello!
A dozen muffins would cost $7.80
----------------------------------------------------------------------------------------------------------------
So if you took for muffins the price would be $2.60 But thats not a dozen
Dozen = 12 muffins
So for 12 muffins you would have to take 4 muffins times 3 (4x3=12)
So to find the price you need to do $2.60 x 3 and you would get $7.80

A container is 8/9 kg of berries is 2/3 full, how many kg can the container hold
Answer:
1.33kg of berries
Step-by-step explanation:
A container is 8/9 kg of berries is 2/3 full, how many kg can the container hold
2/3 of a container = 8/9kg
To get the amount of kg the container can hold, we will write;
1 container = x kg
Divide both expressions
2/3 = 8/9x
Cross multiply
2 * 9x = 3*8
18x = 24
x = 24/18
x = 1.33kg
Hence the container will hold 1.33kg of berries

(4×5)-10-2(1-2)+5
Answer:
12
Step-by-step explanation
PEMDAS is key to solving. First you multiply 4*5 because its the first parenthesis we see, to get 20. Next we see that 1-2 is in a different parenthesis, so we get -2. So our current equation is 20-10-2-1+5. You just add/subtract in that order. 20-10=10 10-2=8 8-1=7 7+5=12 So your final answer is 12.

write the equation that describes the line in slope-intercept form. slope = 5 point (2,-4)
PLEASE HELP!!!
Answer:
y = 5x - 14
slope intercept form is y = mx + b
m = slope
after substituting 5 in for m you end up with y = 5x + b
you substitute (2, -4) for x and y
-4 = 5(2) + b
next step is to solve for b.

The number of bees in a hive doubles every year. A farmer starts a hive with 100 bees. After y years, the hive will contain B bees, where B = 100 · 2ʸ. How many bees will be in the hive after 3 years, assuming the hive continues to grow at this rate? (Answer must be in a complete sentence). *
Answer:
800 bees.
Step-by-step explanation:
If he starts with 100, after a year, it's 200, after another year, it's 400, and after a third year, it's 800.
It will be 800 bees in the hive after 3 years, assuming the hive continues to grow at this rate.
What are exponents?The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.
We are given that number of bees in a hive doubles every year. A farmer starts a hive with 100 bees.
After y years, the hive will contain B bees, where;
B = 100 · 2ʸ.
Therefore, after 3 years, it will be;
B = 100 · 2³
B = 100 x 8
B = 800
Hence, It will be 800 bees in the hive after 3 years, assuming the hive continues to grow at this rate.
