I’m pretty sure the answer is 3 because the z stands for a missing number so 2+3=5

Simplify both sides of the equation.

2+-z=5

-z+2=5

Subtract 2 from both sides.

-z+2-2=5-2

-z=3

Divide both sides by -1

-z = 3

-1 = -1

z=-3

What is 6 1/3 yards in feet with explication

mojhsa [17]

Answer:

6 1/3 yards = 19 feet

Step-by-step explanation:

1 yard = 3 feet

So we'll take the number of yards and multiply that by 3

6 yards x 3 feet/yard = 18 feet

for the 1/3 of a yard, you can either ask, "what's 1/3 of 3?" (= 1) or you can multiply 1/3 yard x 3 feet/yard = 1 foot.

Add up the parts, 18 + 1 = 19 feet

If 75 is added to a number, the result is 39 less than three times the number.find the number

Luba_88 [7]

First, we would set the number to x.

Then, we turn the words into an equation.

x+75 = 3x-39

Isolate the x.

-2x = -114

So...

x = 57

A news agency publishes results of a recent poll. It reports that candidate A leads candidate B by 10% because 45% of the poll p

natali 33 [55]

We need to use the formula to find Margin of Error but through the sample proportion, that is

$E=z*\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}$

We will use a 95% confidence interval, that is a z value of 1.96 (Search in a Normal distribution table)

A) For A our $\hat{p}$ (proportion) is equal to 0.45. So applying the formula,

$E=1.96*\sqrt{\frac{0.45(1-0.45)}{900}}$

$E=3.25\%$

B) We make the same of point A, but change our proportion to 0.35

$E=1.96*\sqrt{\frac{0.35(1-0.35)}{900}}$

$E=3.116\%$

c) We need to calculate the SE through proportion for 0.1, that is

$SE = \sqrt{(\frac{\hat{p_1}(1-\hat{p_1})}{n})+(\frac{\hat{p_2}(1-\hat{p_2})}{n})}$

Then our Error is given by,

$E=z*SE$

$E=1.96*\sqrt(0.45*\frac{0.55}{900}+0.35\frac{0.65}{900}$

$E=0.045$

Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers?

lara [203]

Answer:

11 and 12

Step-by-step explanation:

x=smaller

y=larger

2y=3x-9 x+1=y

2(x+1)=3x-9

2x+2=3x-9

11=x

11+1=y

12=y
