-6 + 2/5c = 24
Answer:
c = 75
Step-by-step explanation:
Add 6 to both sides: 2/5c = 30
Divide both sides by 2/5 (or multiply by reciprocal of 5/2): c = 150/2

If the area of a rectangle is
(15x^2 - 16x - 15) square feet,
and its length is (3x - 5) feet,
find its width.
Answer:
Width = 5x +3
Step-by-step explanation:
15x² - 16x - 15 = 15x² - 25x + 9x - 3 *5
= 5x(3x - 5) + 3(3x - 5)
= (3x - 5)(5x + 3)
Width = [tex]\frac{Area}{length}[/tex]
[tex]= \frac{15x^{2}-16x - 15}{(3x-5)}\\\\=\frac{(3x-5)(5x+3))}{(3x-5)}\\\\=5x + 3[/tex]

Write an equation of the line in point slope form
(2, 4) and (3,6)
Answer:
(y – 4) = 2(x – 2)
Step-by-step explanation:
point slope: y – y₁ = m ( x - x₁ ).
slope: m = ∆y / ∆x.
_______________
m = ∆y / ∆x = [ 6 – 4 / 3 – 2 ] = [ 2 / 1 ]
= 2
____________________________
(2, 4) → (x₁, y₁).
2 → m.
y – y₁ = m(x – x₁) → y – 4 = 2(x – 2).

Find the unit rate.Round to the nearest hundredth,if necessary. 2.99 for 16 lb I REALLY NEED HELP !!!
9514 1404 393
Answer:
0.19/lb
Step-by-step explanation:
When computing cost per quantity, the cost is divided by the quantity.
2.99/(16 lb) = 0.186875/lb ≈ 0.19/lb
Answer:
heyy it's me again lol but The unit rate is $0.19/lb.
Step-by-step explanation:
Divide the total by the number of pounds to get the price per pound, or the unit rate.
$2.99 ÷ 16 lb = 0.186875
Since 0.186875 isn't an accurate US dollar amount, round to nearest hundredth, 0.19.
so you answer is $0.19/Ib

A business analyst is investigating whether the mean amount of purchases made by customers at an online department store is greater than $100. The analyst obtained a random sample of 56 orders and calculated a sample mean of $102.30 and a sample standard deviation of $5.30.
Which of the following is an appropriate test for the investigation?
Answer:
B
Step-by-step explanation:
I don't know
An appropriate test for the investigation is, One sample t-test for sample mean. So option B is correct
What is a random sample ?The process of selecting a sample of data from a population in order to draw conclusions about the population is known as random sampling. Additionally known as probability sampling. Non-probability sampling, often known as non-random sampling, is this sample's opposite. Simple random sampling, stratified sampling, cluster sampling, and multistage sampling are the main forms of this sampling. Convenience samples are often referred to as non-arbitrary samples in sampling methodologies.
Given that,
Population mean = $100
Sample = n = 56
Sample mean = $102.30
sample standard deviation = $5.30
So, all the data mean, standard deviation is given
therefore, t-test used and one type of sample used as well
Hence, It is one-sample t-test for sample mean

What is the value of the expression below when w=5w=5? 4w+9 4w+9
Answer:
29
Step-by-step explanation:
substitute 5 where the w goes in the expression.
It should look like 4 • 5 + 9
Using the order of operations ( PEMDAS ) multiply 4 • 5 to get 20 and then add 9 to get 29
Using the order of operations ( PEMDAS ), the value of the expression is 29.
What is simplification of an expression?Usually, simplification involves proceeding with the pending operations in the expression.
Simplification usually involves making the expression simple and easy to use later.
We need to find the value of the expression below when w = 5w = 5.
Using the order of operations ( PEMDAS ),
Then substitute 5 where the w goes in the expression.
4w+9 = 4 • 5 + 9
4w+9 = 20 + 9 = 29
Using the order of operations ( PEMDAS ), the value of the expression is 29.

Sophia invested $79,000 in an account paying an interest rate of 6.8% compounded
continuously. Assuming no deposits or withdrawals are made, how long would it
take, to the nearest year, for the value of the account to reach $152,800?
Answer:
10
Step-by-step explanation:
The value of the account will reach $152,800 in 10 years.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
Interest compounded continuously means there is no limit for the process of compound of interest. It is compounding infinite times.
The formula for calculating the final amount when the interest is compounded continuously is,
A = P e^(r t)
Here, A is the final amount, P is the initial or principal amount, r is the rate of interest and t is the number of years.
Given that,
A = $152,800
P = $79,000
r = 6.8% = 6.8/100 = 0.068
We have to calculate t.
152,800 = 79,000 e^(0.068 t)
152,800 / 79000 = e^(0.068 t)
1.934 = e^(0.068 t)
Taking logarithms on both sides,
㏑ 1.934 = ㏑ e^(0.068 t)
We have ㏑(a)ⁿ = n ㏑(a)
0.65968 = 0.068t ㏑ e
0.65968 = 0.068 t × 1
t = 9.7 ≈ 10 years
Hence the amount is compounded to $152,800 in 10 years.
