How many solutions are there to the equation 11x+25=7x+15

Answers

Answer 1

Answer: Just one 11x+25=7x+15 11x - 7x = 15 -25 4x = -10 x = -10/4 x = -5/2

Answer 2

Answer: There is only one solution for this equation which is x = -2.5 11x+25=7x+15 11x+25-7x=15 11x-7x=15-25 4x= -10 x = -10/4 x = -5/2 x = -2.5

Find z if X=27, μ=20, and α=3.4. Round to the nearest hundredth if necessary.A. 2.06

B. –2.06

C. 1.18

D. 0.35

Answers

Answer:

A. $Z=2.06$

Step-by-step explanation:

We want to find the Z-score of $X=27$ if the population mean is $\mu=20$ ,and the population standard deviation is $\sigma=3.4$ .

We use the formula:

$Z=(X-\mu)/(\sigma)$

We substitute the values to obtain:

$Z=(27-20)/(3.4)$

$Z=(7)/(3.4)$

$Z=2.06$

The correct answer is A.

Question: Michelle is making goodie bags for Christmas filled with chocolate and candy. Chocolates cost $2.50 per lb and candy cost $3.00 per lb. Michelle spent a total of $40 on 20 lbs of candy. How much of each kind of candy did she purchase ?

Answers

Michelle purchased 5 lbs of chocolates and 5 lbs of candy.

Let assume Michelle purchased x lbs of chocolates and y lbs of candy.

According to the given information,

Michelle spent a total of $40 on 20 lbs of candy.

So, the equation can be set up as:

Equation 1: 2.50x + 3.00y = 40

As, the totalweight of candy is 20 lbs, so we have:

Equation 2: x + y = 15

From equation 2: x = 15 - y

Substitute the value of x= 15 - y into Equation 2 as

2.5(15-y) + 3y = 40

37.5 - 2.5y + 3y= 40

0.5y = 2.5

y= 5

Substituting y= 5 into the second equation

x + 5 = 10

x = 10 -5

x = 5

Thus, 5 lbs of chocolates and 5 lbs of candy were bought.
