Answer:

x=-3

Step-by-step explanation:

3x + 2 = x + 4(x+2)

Expand the brackets.

3x + 2 = x + 4x+8

3x + 2 = 5x+8

Subtract -5x and -2 from both sides of the equation.

3x-5x=8-2

-2x=6

\frac{-2x}{-2}=\frac{6}{-2}

Divide -2 on both sides of the equation.

x=-3

Given that (5,-8) is on the graph of f(x), find the corresponding point for the function f(x+2)
galben [10]
We know that
the transformation
f(x)--------> f(x+2)
that means
A point (x,y) in graph of f(x)------> become a point (x-2, y) in graph of f(x+2)

hence
point (5,-8)-------------> become a point (5-2,-8)-----> (3,-8)

the answer is
the point (3,-8)

Suppose that IQ scores have a bell-shaped distribution with a mean of 104 and a standard deviation of 17. Using the empirical ru
Shalnov [3]

Answer:

By the Empirical Rule, 68% of IQ scores are between 87 and 121

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 104

Standard deviation = 17

Using the empirical rule, what percentage of IQ scores are between 87 and 121

87 = 104 - 1*17

So 87 is one standard deviation below the mean

121 = 104 + 1*17

So 121 is one standard deviation above the mean

By the Empirical Rule, 68% of IQ scores are between 87 and 121

8. Find the area of the following triangle.<br> h=8m<br> b= 6.5
torisob [31]

Answer:

26m^2

Step-by-step explanation:

Area of triangle=1/2b*h

We have,

b=6.5

h=8m

Now,

Area=1/2b*h=1/2*6.5*8=26m^2
