Answer:

In order of least money saved to most money saved: Katrina, Susan, Gabrielle, Savanna

Step-by-step explanation:

You can first change all of them to either percentages or fractions with the same denominator. I chose to use percentages. Thus Savanna's percentage of money saved would be 90%, Katrina would've saved 80% and Susan would've saved around 83%.

From here you just order from least to greatest.

Men’s heights are normally distributed with a mean of 71.8 inches and a standard deviation of 3.4 inches. A social organization

nadya68 [22]

Answer: 2.28%

Step-by-step explanation:

μ = 71.8

σ = 3.4

X < 65

P(X < 65) = P (Z < 65 - 71.8/3.4) = P (Z < -2)

According to the table for the normal distribution attached, it will give us

P (z < Z < 0), this way, to find the P(Z < z), we need to do 0.5 - P:

0.5 - P(-2 < Z < 0) = 0.5 - 0.4772 = 0.0228

In percentage: 0.0228*100 = 2.28%

If 3x−y=12, what is the value of 8x/2y?

patriot [66]

Answer:

17.2

Step-by-step explanation:

3x=12+y

x=12+y/3

$8( \frac{12 + y}{3}) \div 2y$

$\frac{96 + 8y}{3} \times \frac{1}{2y}$

$\frac{96 + 8y}{6y}$

(y is divided by y so it no longer exists)

$\frac{96 + 8}{6}$

$\frac{104}{6}$

$17.2$

Consider the equation (x−4)(x+3)=0.

Jlenok [28]

Answer:

(1) x (x+ 3) - 4 (x +3) = 0

(2) x = 4 and x = -3

Step-by-step explanation:

given data

equation

(x−4)(x+3)=0

solution

given equation (x−4)(x+3) = 0

equation as a compound statement is

x (x+ 3) - 4 (x +3) = 0

and

two solutions to the equation are

so x (x+ 3) - 4 (x +3) = 0

x- 4 = 0 and x + 3 = 0

x = 4 and x = -3
