Answer:

**Answer:**

27.825

**Step-by-step explanation:**

Sure!

To turn a fraction into a decimal you simply divide 33 by 40. The whole number - 27 - can stay.

27 33/40 = 27 + (33/40)

= 27 + 0.825

= 27.825

Answer:

Step-by-step explanation:

This is a test of a single population mean since we are dealing with mean.

From the information given,

Null hypothesis is expressed as

H0:μ=1.5

The alternative hypothesis is expressed as

Ha:μ>1.5

This is a right tailed test

The decision rule is to reject the null hypothesis if the significance level is greater than the p value and accept the null hypothesis if the significance level is less than the p value.

p value = 0.052

Significance level, α = 0.05

Since α = 0.05 < p = 0.052, the true statement would be

At the α=0.05 significance level, you have proven that H0 is true. B.

**Answer:**

$6.6

**Step-by-step explanation:**

We are given that Maria bought 1 2/5 pounds or 7/5 pounds of lunch meat for $3.36.

Now to find how much would 2 3/4 pounds or 11/4 pounds of lunch meat cost, we will have to first find how much would 1 pound of lunch meat cost.

In order to find that we will apply unitary method here.

So cost of 7/5 pounds of meat = $3.36

Cost of 1 pound of meat = 3.36/(7/5) = $2.4

Cost of 11/4 pounds of meat = 2.4 * (11/4) = $6.6

So the cost of 2 3/4 pounds of lunch meat would be $6.6.

**Answer:**

the answer is 6.6

i took the quiz and got it right

Answer: 7a+3

Step-by-step explanation:

9a and 2a are two like terms that we can combine. Because there is a minus sign in front of the 2a, we should subtract 9a from 2a to get

7a. Then because the 3 has plus sign in front of it, we add 7a to 3. BUT because 3 a is NOT a like term, you don’t actually add it, so it looks like this: 7a+3. Hope this helped!

7a+3 because the 9 and 2 are from the same family since they both have a so u combine then and u cant combine 3 with anything so that’s left over

s = t-2

s=4/t+2

s=t+2/4

s=t+6

B= S=4/t+2

whenever you have the equation 4 x = t+2 you are trying to isolate the X by doing that you have ti take the 4 and divide it to the other side so the x can stay on that side

whenever you have the equation 4 x = t+2 you are trying to isolate the X by doing that you have ti take the 4 and divide it to the other side so the x can stay on that side

Answer:

$615.72

Step-by-step explanation:

Use the compound interest formula and substitute the given value: A=$500(1+0.21/12)^12(1)

Simplify using order of operations: A=$500(1.0175)^12=$500(1.231439315)

=$615.72

**Answer:**

$558.68

**Step-by-step explanation:**

The amount of each monthly payment is given by the amortization formula:

A = P(r/n)/(1 -(1 +r/n)^(-nt)

where P is the principal borrowed, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.

We want to find nA where we have n=12, r=0.21, t=1, P=500. Filling in these values, we get ...

nA = Pr/(1 -(1 +r/n)^-n) = $500(0.21)/(1 -1.0175^-12) = **$558.68**

**The total amount needed to repay the loan in 1 year is $558.68**.

y=2x-3

**Answer:**

(0, -3) and (4, 5)

**Step-by-step explanation:**

y = x² − 2x − 3

y = 2x − 3

2x − 3 = x² − 2x − 3

0 = x² − 4x

0 = x (x − 4)

x = 0 or 4
