Answer:

-21 and 40.

Step-by-step explanation:

The two numbers from the list that have a difference of 29 are:

-21 and 40.

-21 - (-40)

= -21 + 40

= 29

The two numbers are -21 and 40.

Answer:

-16-(-45)

Step-by-step explanation:

If we subtract -45 from -16, we'll get the result 29

=> -16-(-45)

=> -16+45

=> 29

A random sample of 100 people was taken. Eighty of the people in the sample favored Candidate A. We are interested in determinin

riadik2000 [5.3K]

Answer:

Option b - not significantly greater than 75%.

Step-by-step explanation:

A random sample of 100 people was taken i.e. n=100

Eighty of the people in the sample favored Candidate i.e. x=80

We have used single sample proportion test,

$p=\frac{x}{n}$

$p=\frac{80}{100}$

$p=0.8$

Now we define hypothesis,

Null hypothesis $H_0$ : candidate A is significantly greater than 75%.

Alternative hypothesis $H_1$ : candidate A is not significantly greater than 75%.

Level of significance $\alpha=0.05$

Applying test statistic Z -proportion,

$Z=\frac{\widehat{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n}}}$

Where, $\widehat{p}=80\%=0.80$ and $p=75%=0.75$

Substitute the values,

$Z=\frac{0.80-0.75}{\sqrt{\frac{0.75(1-0.75)}{100}}}$

$Z=\frac{0.80-0.75}{\sqrt{\frac{0.1875}{100}}}$

$Z=\frac{0.05}{0.0433}$

$Z=1.1547$

The p-value is

$P(Z>1.1547)=1-P(Z$

$P(Z>1.1547)=1-0.8789$

$P(Z>1.1547)=0.1241$

Now, the p-value is greater than the 0.05.

So we fail to reject the null hypothesis and conclude that the A is not significantly greater than 75%.

Therefore, Option b is correct.

The angles 3x+6 and 5x + 6 are supplements. What are the two angles

yarga [219]

Answer:

x = 21

Step-by-step explanation:

Step 1: Make an expression

Since they are supplements, that means that they add up to 180 degrees.

3x + 6 + 5x + 6 = 180

Step 2: Combine like terms

3x + 6 + 5x + 6 = 180

(3x + 5x) + (6 + 6) = 180

8x + 12 = 180

Step 3: Subtract 12 from both sides

8x + 12 - 12 = 180 - 12

8x = 168

Step 4: Divide both sides by 8

8x / 8 = 168 / 8

x = 21

Answer: x = 21

Alex has 128 photos of his friend to display equally in 4 photo albums. Which equation can you use to find how many will be in e

Trava [24]

Answer:

128 ÷ 4 = $\frac{128}{4}=32$

Step-by-step explanation:

Total number of photos = 128

Number of photo albums = 4

Alex has 128 photos of his friend to display equally in 4 photo albums.

Equation that can be used to find number of photos in each album =

Number of photo albums ÷ Total number of photos

= 128 ÷ 4

= $\frac{128}{4}=32$

Step-by-step explanation:

h = 3 in

base 1 = 6 in

base 2 = 9 in

So plug in

A = 1/2 (3) (6 + 9)

A = 3/2 (15)

A = 22.5 in^2

set both (x-4) and (x+2) equal to zero

x-4=0

x=4

& bx+2=0

x=-2

c has 4 and -2 as x values
