Answer:

New value =

25 + Percentage increase =

25 + (23% × 25) =

25 + 23% × 25 =

(1 + 23%) × 25 =

(100% + 23%) × 25 =

123% × 25 =

123 ÷ 100 × 25 =

123 × 25 ÷ 100 =

3,075 ÷ 100 =

What is the y-intercept of y = 5x - 1?

Serhud [2]

Answer:

Given Equation: y=5x-1

as we know that the y intercept have, x coordinate(absicasse) equal to 0

so,put x=0 to get y intercept

i.e, y =5×0 -1

i.e, y= -1

$\angle{DBC }$ =(5x+4)°

$\angle{ A }$ =(2x-2)°

$\angle{C }$ =(4x-6)°

we know that,

$\angle{DBC}$ = $\angle{A}$ + $\angle{C}$

According to the question,

$\tt{ 5x+4=2x-2+4x-6 }$

$\tt{ 5x+4=6x-8 }$

$\tt{ 6x-5x=4+8 }$

$\blue{x=12 }$

so,

$\angle{C }$ =(4x-6)°=(4×12-6)°=(48-6)°=42°

Suppose that documentation lists the average sales price of a single-family home in the metropolitan Dallas/Ft. Worth/Irving, Te

Julli [10]

Answer:

"0.0373" seems to be the appropriate solution.

Step-by-step explanation:

The given values are:

n₁ = 43

n₂ = 35

$\bar{x_1}=217800$

$\bar{x_2}=204700$

$\sigma_1=30300$

$\sigma_2=33800$

Now,

The test statistic will be:

⇒ $Z=\frac{\bar{x_1}-\bar{x_2}}\sqrt{\frac{\sigma_1^2}{n_1} +\frac{\sigma_2^2}{n_2} }$

On substituting the given values in the above formula, we get

⇒ $=\frac{217800-204400}{\sqrt{\frac{(30300)^2}{43} +\frac{(33800)^2}{35} } }$

⇒ $=\frac{217800-204400}{\sqrt{\frac{918090000}{43} +\frac{1142440000}{35} } }$

⇒ $=\frac{13400}{7347.93}$

⇒ $=1.7828$

then,

P-value will be:

= $P(Z>1.7828)$

= $0.0373$
