BRAINLIEST + 25 POINTS
Part A: a^2 + 6 for a = 5
Part B: Show your work and/or explain how you arrived at your answer
Answer:
31
Step-by-step explanation:
Plug in 5 as a into the expression:
a² + 6
(5)² + 6
25 + 6
= 31
So, the answer is 31 when a = 5
substitute a=5 into the equation.
5²+6
25+6=31

Answer:
(4,0)
Step-by-step explanation:
Please help will give brainliest.
Answer:
D
Step-by-step explanation:
a is false since x could be 0.
b is easy to check, just plug numbers in, and we can see that it's false(you would get 0+0=1 and -0-0=-1 once plugged in)
c is also easy to check, just plot the line or simplify the first equation. since (2x+2y)/2=4/2 is also x+y=2, the second equation is also x+y=2, so it must have infinitely many solutions.
d must be true due to process of elimination but let's check to make sure.
7y=14x, divide both sides by 7 to get y=2x and since they're the same equation it must mean that they have infinitly many solutions and we can see that it is correct

Find the circumference of the circle.
10 cm
The circumference is cm.
(Type an exact answer in terms of t.)
Answer:
the answer is either one or two answers
62.83 or 31.42
Step-by-step explanation:
This is the formula i used.
C=2πr
Circumference = 2·π·5 ≈ 31.41593 / 2·π·10 ≈ 62.83185
therefore,
t = 31.41593
or
t = 62.83185

Solve 5x -2.5 = 17.5
Answer:
x=4
Step-by-step explanation:
5x-2.5=17.5
5x=17.5+2.5
5x=20
x=20/5
x=4
The solution of the given equation is x=4
What does it mean to solve an equation?An equation represents equality of two or more mathematical expression.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Solutions to an equation are those values of the variables involved in that equation for which the equation is true.
We are given the equation as;
5x-2.5=17.5
Solving for x;
5x=17.5+2.5
5x=20
x=20/5
x=4

The branch manager of an outlet (Store 1) of a nationwide
chain of pet supply stores wants to study characteristics of her
customers. In particular, she decides to focus on two variables: the
amount of money spent by customers and whether the customers
own only one dog, only one cat, or more than one dog and/or cat.
The results from a sample of 70 customers are as follows:
Amount of money spent: X = +21.34, S = +9.22.
Thirty-seven customers own only a dog.
Twenty-six customers own only a cat.
Seven customers own more than one dog and/or cat.
Construct a 95% confidence interval estimate for the
population mean amount spent in the pet supply store.
Construct a 90% confidence interval estimate for the population proportion of customers who own only a cat.
The branch manager of another outlet (Store 2) wishes to conduct
a similar survey in his store. The manager does not have access to
the information generated by the manager of Store 1. Answer the
following questions:
c. What sample size is needed to have 95% confidence of
estimating the population mean amount spent in this store
to within { +1.50 if the standard deviation is estimated to
be $10?
d. How many customers need to be selected to have 90% confidence of estimating the population proportion of customers who own only a cat to within {0.045?
e. Based on your answers to (c) and (d), how large a sample should the manager take?
Answer:
1. ( 19.1416, 23.5384,)
2. (0.276348, 0.46651)
3. the sample size = 170.73 approximately 171
4. sample size = 334.07 approximately 334
5. sample of 334 should be taken by manager
Step-by-step explanation:
mean = bar x = 21.34 dollars
size of sample n = 70
standard deviation of sample = 9.22
we use t distribution as the population standard deviation is not known.
95% Confidence interval
1-α = 0.95
α = 0.05
degree of freedom = 70-1 = 69
α/2 = 0.025
using the t distribution tsble,
= 1.9949
confidence interval = [tex]21.34+-1.9949*[\frac{9.22}{sqrt(70)}] \\[/tex]
= 21.34 +- (1.9949*1.10200)
= 21.34 + 2.1984, 21.34 - 2.1984
= (23.5384, 19.1416)
the confidence interval of the mean amount spent at the supply store can be written as 19.1416<u<23.5384
2. sixe of those who only have a cat
p = 26/70 = 0.371429
at 90 % confidence interval,
1-α = 0.90
α = 0.10
we use the z table here
z(0.10/2) = Z(0.05)
= 1.645
[tex]0.371429+-1.645\sqrt} \frac{0.371429(1-0.371429)}{70}[/tex]
= 0.371429 +-( 1.645 x 0.0578)
= 0.371429 + 0.095081, 0.371429 - 0.095081
= (0.276348, 0.46651)
3. sd = 10$
margin of erro,r e = 1.50$
α = 0.05
using z table
α/2 = Z0.025
= 1.96
sample size = 1.96² * 10² / 1.50²
= 3.8416 * 100/ 2.25
= 170.73
the sample size is approximately 171
d. we have 0.5 as sample proportion now
margin of error = 0.045
α = 0.10
Zα/2 = 0.05
= 1.645
sample size = 1.645²x0.5(1-0.5) / 0.045²
= 0.676506/0.002025
= 334. 07
sample size = 334
5. sample of 334 should be taken by manager

Answer:
1,795 mi. traveled in total
Step-by-step explanation:
3 × 65 = 195 mi. driven by car
4 × 400 = 1,600 mi. flown by jet
1,600 + 195 = 1,795 mi. traveled in total.
