PLZ ans have mocks plz

Yanka [14]

Answer:

The table will be:

x |-2 | -1 | 0 | 1 | 2

y | 1 | 4 | 5 | 4 | 2

Step-by-step explanation:

The function is:

$y=5-x^{2}$

a) The x values of the table is:

x |-2 | -1 | 0 | 1 | 2

So, when x = -2, y will be:

$y(-2)=5-(-2)^{2}=5-4=1$

Doing the same with the other x values we have:

$y(-1)=5-(-1)^{2}=5-1=4$

$y(0)=5-(0)^{2}=5$

$y(1)=5-(1)^{2}=5-1=4$

$y(2)=5-(2)^{2}=5-4=1$

The table will be:

x |-2 | -1 | 0 | 1 | 2

y | 1 | 4 | 5 | 4 | 1

I hope it helps you!

Carol wants to make a sculpture using brass and aluminum, with the dimensions shown below, Aluno Bree The area of the aluminum s

mars1129 [50]

The aluminum section's area formula solved for h is $h =\frac{A}{a - b}$

From the complete question, the expression of the area (A) in terms of variables a, b and h is:

$A = ah - bh$

Factor out h from the expression on the right-hand side

$A = h(a - b)$

Divide both sides of the equation by (a - b)

$\frac{A}{(a - b)} = h$

Remove the bracket

$\frac{A}{a - b} = h$

Rewrite the above equation as follows:

$h =\frac{A}{a - b}$

Hence, the aluminum section's area formula solved for h is $h =\frac{A}{a - b}$

For a standardized psychology examination intended for psychology majors, the historical data show that scores have a mean of 50

Volgvan

Answer:

$P(\bar X>530)=1-0.808=0.192$

Step-by-step explanation:

1) Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Let X the random variable that represent the scores, and for this case we know the distribution for X is given by:

$X \sim N(\mu=505,\sigma=170)$
