5 more than the product of 23 and a number n

denis-greek [22]

Answer:

23n +5

Step-by-step explanation:

break down the expression into parts

5 more is +5

product is multiplication of 23 and n so 23n

then put it together

2) find an equation of the line theough the given

Olenka [21]

Answer:

y = -2x + 2

Step-by-step explanation:

Given the following data;

Points on the x-axis (x1, x2) = (2, -1)

Points on the y-axis (y1, y2) = (-2, 4)

To find the equation of line in slope intercept form;

First of all, we would determine the slope of the line.

Mathematically, slope is given by the formula;

$Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis}$

$Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}}$

Substituting into the equation, we have;

$Slope, m = \frac {4 - (-2)}{-1 -2}$

$Slope, m = \frac {4 + 2}{-1 -2}$

$Slope, m = \frac {6}{-3}$

Slope, m = -2

Next, we would use the following formula to find the equation of the line;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - (-2) = -2(x - 2)

y + 2 = -2x + 4

y = -2x + 4 - 2

y = -2x + 2 = mx + c

s344n2d4d5 [400]

Answer:

a

$10,151 $< \mu$ $11448.12

b

$n = 158$

Step-by-step explanation:

From the question we are told that

The sample size is n = 19

The sample mean is $\= x =$ $10,800

The standard deviation is $\sigma =$ $1095

The population mean is $\mu =$ $225

Given that the confidence level is 99% the level of significance is mathematically represented as

$\alpha = 100 -99$

$\alpha = 1$ %

=> $\alpha = 0.01$

Now the critical values of $\alpha = Z_{\frac{\alpha }{2} }$ is obtained from the normal distribution table as

$Z_{\frac{0.01}{2} } = 2.58$

The reason we are obtaining values for $\frac{\alpha }{2}$ is because $\alpha$ is the area under the normal distribution curve for both the left and right tail where the 99% interval did not cover while $\frac{\alpha }{2}$ is the area under the normal distribution curve for just one tail and we need the value for one tail in order to calculate the confidence interval
