A group of 12 students is deciding whether to go to the science center or the zoo. Science center tickets are 3 for $36.75 and zoo tickets are 4 for $51.
How much will a group of 12 students save by choosing the science center?
Enter your answer in the box.
ANSWER:
$6
ExPLANATION:
Step 1:
36.75 × 4 = 147
Step 2:
51 × 3 = 153
Step 3:
153 - 147 = 6
The group of 12 students will save $6 by visiting the science center instead of the Zoo.
Science center fee :
3 tickets = $36.75 Total cost of visiting Science center = (12/3) × 36.75 = $147Zoo Fee :
4 tickets = $51Total cost of visiting Zoo = (12/4) × 51 = $153The difference in the total amount spent :
Total cost of Zoo - Total cost of Science center $153 - $147 = $6Therefore, the group will save $6 by visiting the science center.

If the surface area of a cylinder is 800 in^2 and the height is 15 in, what is the base?
Answer:
base = diameter
Step-by-step explanation:
if the surface area of the cylinder is 800...
the height is 15... then the formula must be 3.14 x 15 x R2
r squared is supposed to be the square of the radius of the cylinder\
conclusion: 3.14 x 15 x R2 is 800_
so.multiply then..find the radius and add the answer you get to find the diameter ..For employees at a large company, the mean number of overtime hours worked each week is 9.2 hours with a population standard deviation of 1.6 hours. A random sample of 49 employees was taken and the probability that the mean number of overtime hours will be at least 9.3 hours was determined. Was the probability a Left-tail, Right -tail or Interval Probability? Use a calculator to find the probability that the mean overtime hours for the sample will be at least 9.3 hours. Select the two correct answers that apply below.
Complete Question
Answer:
The probability is Right- tailed
The mean overtime hours for the sample will be at least 9.3 hours is
[tex]P(X \ge 9.3 ) = 0.3333[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 9.2 \ hours[/tex]
The standard deviation is [tex]\sigma = 1.6 \ hours[/tex]
The sample size is n = 49
The sample mean is [tex]\= x = 9.3[/tex]
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_{\= x} = \frac{1.6 }{\sqrt{49} }[/tex]
=> [tex]\sigma_{\= x} = 0.22857[/tex]
This is a right -tailed probability because the sample mean is greater than the population mean
Generally the probability that the mean overtime hours for the sample will be at least 9.3 hours is mathematically represented as
[tex]P(X \ge 9.3 ) =1 - P(X < 9.3 )[/tex]
So
[tex]P(X < 9.3 ) = P( \frac{ X - \mu }{ \sigma_{\= x }} < \frac{ 9.3 - 9.2 }{ 0.22857} )[/tex]
Here [tex]\frac{X - \mu }{\sigma _{\= x}} = Z[/tex]
[tex]P(X < 9.3 ) = P( Z < 0.43750)[/tex]
From the z-table
[tex]P(X < 9.3 ) = P( Z < 0.43750) = 0.667[/tex]
So
[tex]P(X \ge 9.3 ) =1 - 0.667[/tex]
[tex]P(X \ge 9.3 ) = 0.3333[/tex]

A study took a random sample often married couples, and asked the husband's and wife's age. The scatterplot shows the association between the ages of the husbands and wives. Not surprisingly, older husbands tend to have older wives, so the data has a positive linear association. A researcher finds that the least squares regression equation for this relationship is ŷ= 0.89 x + 2.62.
Suppose you interview a married man who has lived to the ripe old age of 100, and still married to his wife. using the least squares regression equation, predict his wife's age.

Lances goal is to run 16 laps around the track. Each lap is 350 yards. Currently lances ran 2450 yards around the track. How much is his percent did he run so far??
Answer:
Hi There!
Your answer is :
He ran 43.75% so far.
Step-by-step explanation:
16 laps = GOAL
350* 16 to determine goal yards
16laps = 5,600yrds
1 lap= 350 yrds
xlaps = 2450 yrds
2450/350 to determine x laps.
7 laps = 2450 yards
He is 2450 yards into his 5,600 yard goal.
IF 5,600 = 100%
/5600
1 yard = 1/56th %
* 2450
2450yards = 43.75%

Answer:
x = 15
Step-by-step explanation:
The definition of alternate interior angles means that both of these labeled angles will be equal. Therefore, 60 = (3x + 15)
60 = 3x + 15
Divide this by 3 on both sides
20 = x + 5
Subtract 5 from both sides
15 = x or x = 15
3/4-1/12 subtract and simplify
Answer:
2/3
Step-by-step explanation:
Simplify the following:
3/4 - 1/12
Put 3/4 - 1/12 over the common denominator 12. 3/4 - 1/12 = (3×3)/12 - 1/12:
(3×3)/12 - 1/12
3×3 = 9:
9/12 - 1/12
9/12 - 1/12 = (9 - 1)/12:
(9 - 1)/12
9 - 1 = 8:
8/12
The gcd of 8 and 12 is 4, so 8/12 = (4×2)/(4×3) = 4/4×2/3 = 2/3:
Answer: 2/3
Let f(x) = 2x + 1, g(x) = 3x - 2. Find the function (f - g)(x)
Answer:
Step-by-step explanation:
I thought they corrected this problem. Apparently not. I have to change eff(x). Change it to y
You can read this as y - g(x)
y - g(x) = 2x + 1 - 3x + 2
y - g(x) = -x + 3
There are 52 contacts in your phone. The only family members' numbers you have are your dad's, mom's, and brother's. What are the odds of selecting a number in your phone that is not your family? Write your answer as 1:2 which is reduced as much as possible.
Answer:
49:52
Step-by-step explanation:
Given that:
Total number of contacts on phone = 52
Family members in phone book : dad, mom, brother
Total number of family members = 3
Hence, non family members = 52 - 3 = 49
Number of family members to total phone contact
Selecting a contact that is not a family member :
49 : 52
