Answer:

[tex]f^{-1}[/tex](x)=2x+10

Step-by-step explanation:

f(x)=[tex]\frac{x}{2}[/tex]-5

Let y= [tex]\frac{x}{2}[/tex]-5

y= [tex]\frac{y}{2}[/tex]-5

x+5= [tex]\frac{y}{2}[/tex]

Both side multiple 2,

2x+10=y

[tex]f^{-1}[/tex](x)=2x+10

Answer:

A = 76

Step-by-step explanation:

Formula of the area of a triangle: [tex]A=\frac{h*b}{2}[/tex]

Formula of a rectangle: [tex]A=l*w[/tex]

So starting with the triangle...You know that the height of the triangle is 7, and the base of the triangle is 8 because the base of the rectangle is the same as the triangle's base...

Now using the formula of the triangle...

A = [tex]\frac{7*8}{2}[/tex]

= 28

Now find the area of the whole retangle...The length of the rectangle is 13 because 7+6=13; the width is 8

Now using the formula of the rectangle...

A = [tex]13*8[/tex]

= 108

Now that you have the areas of both the triangle and the retangle...Do subtraction to find the shaded area...

[tex]108 - 28 = 76[/tex]

Answer:

B. Yes! Jason has printed 73/100 of the posters needed.

Step-by-step explanation:

7/10(1500) = 1050 minimum to print

1500-400 = 1100 printed

1100/1500 = 73/100

This question is incomplete, the complete question is;

4. A scale measuring trust inthe media was administered to a random sample of 114 Democrats and 112 Republicans. The researcher finds that Democrats average a score of 8.5 on this scale, while Republicans average a score of 7.8. Together the Democrats and Republicans have a pooled standard error of .32. Is there a statistically significant difference between Democrats and Republicans in their level of trust in the media (at the alpha = .05 level )

Answer:

p-value 0.0297

Hence, p value ( 0.0297 ) is LESS THAN ∝ ( 0.05 )

Therefore, this is sufficient evidence to conclude that there is difference between Democrats and Republicans in their level of trust in the media.

Step-by-step explanation:

Given the data in the question;

H₀ : u₁ = u₂

Hₐ : u₁ ≠ u²

test statistics

t = x - u / s

we substitute

t = ( 8.5 - 7.8 ) / 0.32

t = 0.7 / 0.32

t = 2.1875

∝ = 0.05

degree of freedom = n₁ + n₂ - 2 = 114 + 112 - 2 = 224

so

{t[tex]_{\alpha /2[/tex], [tex]_{df[/tex] } =  {t[tex]_{0.025[/tex], [tex]_{224[/tex] } = 1971

p-value = 0.02974

p-value 0.0297

Hence, p value ( 0.0297 ) is LESS THAN ∝ ( 0.05 )

Therefore, this is sufficient evidence to conclude that there is difference between Democrats and Republicans in their level of trust in the media.

Answer:

The perimeter of the given parallelogram increases to four times the current value

Step-by-step explanation:

The given dimensions of the parallelogram are 8 cm by 10 cm

Therefore, the perimeter of the given parallelogram, 'P₁', is found as follows;

P₁ = 2 × 8 cm + 2 × 10 cm = 16 cm + 20 cm = 36 cm

The perimeter of the given parallelogram, P₁ = 36 cm

When each side of the parallelogram are multiplied by 4, we get;

The new sides of the parallelogram = 4 × 8 cm = 32 cm and 4 × 10 cn = 40 cm

The new perimeter of the parallelogram, P₂ = 2 ×32 cm + 2 × 40 cm = 144 cm

Therefore, the perimeter, P₂ is P₂/P₁ times larger than the perimeter P₁

P₂  = (144 cm)/(36 cm) × P₁

∴  P₂  = 4 × P₁

The change in the perimeter after multiplying each side of the given parallelogram by 4 is that the perimeter of the given parallelogram increases to four times the current value

Equality Properties

Step-by-step explanation:

Step 1: Define

15.6 < 2.7(z - 1) - 0.6

Step 2: Solve for z

Here we see that any value z greater than 7 would work as a solution to the inequality.

Answer:

4x3x2x1=24

Step-by-step explanation:

Answer:

here's your solution

=> percent means divided by 100

=> to find 40% of a number ,

=> we have to think for a number here it

is not given

=> so, we have to assume it , then let the

number be X

=> now ,. equation= 40/100*x

=> 40/100*X
