coldgirl [10]

Answer:

$6.75 and $4.50

Step-by-step explanation:

a) Jamal spent:

Isaiah spent:

3 (x - 2.25)

The equation is:

2x = 3(x - 2.25)

b) Solving the equation

2x = 3x - 6.75
3x - 2x = 6.75
x = 6.75

c) Jamal's items cost

$6.75 each

Isaiah's items cost

$6.75 - $2.25 = $4.50 each

A random variable r is normally distributed with a mean of 7 and a standard deviation of 1.5. Find the value of w so that P (8.8

a_sh-v [17]

Answer:

The answer is explained below

Step-by-step explanation:

Given that:

mean (μ) = 7 and standard deviation (σ) = 1.5.

The z score is used in statistic used to measure the number of standard deviation by which the raw score is above or below the mean value. It is given by:

$z=\frac{x-\mu}{\sigma}, where\ x\ is\ the \ raw\ score$

To find the Probability that x < 8.8, we first find the z score using:

$z = \frac{x-\mu}{\sigma}=\frac{8.8-7}{1.5}=1.2$

From the z tables, P(x < 8.8) = P(z < 1.2) = 0.8849 = 88.49%

Evaluate f(x) = X(With an exponent of 2) -3x +2, given f(x + 1).

Lana71 [14]

Answer:

f(x + 1) = x² - x

Step-by-step explanation:

f(x) = x² - 3x + 2 when f(x + 1)

f(x + 1) = (x + 1)² - 3(x + 1) + 2

f(x + 1) = (x² + 2x + 1) + (-3x - 3) + 2

f(x + 1) = x² - x + 0

f(x + 1) = x² - x

Best of Luck!
