Answer:

the answer is letter B

Step-by-step explanation:

correct me if i wrong

PART A:

Solve for the slope by solving change in y over change in x. We have (3-(-5)/(-2-2) = 8/-4=-2

PART B:

Change in to y=mx+b: -5y = -2x-10. Divide all terms by -5: y = 2/5x + 2. The slope is 2/5 and the y-intercept is 2.

PART C:

Remembering from part a that m=change in y/change in x, we have the equation: -4=1-(-9)/0-x. If we simplify, we have -4=10/0-x. If we multiply both sides from 1/10 we have: -2/5 = -x. So, x = 2/5.

PART D:

We can use point-slope form first:

y-5=-7(x+1). Then we solve the equation! y-5 = -7x-7. After adding 5 to both sides, we have the equation: y=-7x-2.

Answer:

Solve for x, y, and z. 1st Equation: 2x + 2y + 4z = 48. 2nd Equation: 2x + 9y + 7z = 105. 3rd Equation: x + 4y + z = 37. Subtract the 2nd Equation from the 1st Equation. This will eliminate the variable “x”.

Answer: Below

Step-by-step explanation:

So we start off with b and f. Our first piece of information, Bill baked 3 times as many as Felicia, gives us the equation:

b = 3f

The second piece gives us the equation:

b = f + 24

We have a 3f, but no b = f + 24 in the possible answers. So:

b = f +24

b - 24 = f

Our answer is A.

Answer:

The Answer is B

Answer:

We can first determine it is not A or C, because these flatly do not equal the expression above.

I believe is it D, because of the commutative property.

The associative property of addition states that you can group the addends in different ways without changing the outcome. While the commutative property of addition states that you can reorder the addends without changing the outcome.

In this case, we are rearranging the addends, not groups of them.

Answer:

Step-by-step explanation:

The gross pay that shows up on your paycheck is the sum of wages, commissions, and any other earnings your employer may share with you (tips, insurance offsets, bonuses). From this gross pay, government regulations may require the deduction of taxes of various kinds. Your employer may deduct the cost of insurance, and you may voluntarily have amounts deducted for additional taxes, insurance, union dues, or retirement plan contributions. The pay that you take home is the net pay after these deductions.

__

Chien gets paid at the rate of $15 per hour for 20 hours per week and 2 weeks per pay-period. We are not told of any other earnings or contributions to his gross pay. So, it will be ...

  ($15/h)(20 h/wk)(2 wk/period) = $600/period

Chien's gross pay will be $600 each pay period.

__

As discussed above, "net pay" and "take-home pay" are synonymous.

__

As discussed above, there may be a variety of deductions from his gross pay that will reduce his net pay. Often the largest of these is income tax together with Social Security tax. There may be additional deductions for insurance, union dues, health plan contributions, and retirement plan contributions.

__

Chien's budget should be based on money he actually has available to spend. That would generally be his net pay.

If Chien is considering changing jobs or his family situation, changes to payroll deductions may figure into his budget. Ordinarily, those costs would be considered "fixed" and not subject to a budgeting process.

Answer:

6. mean = 1.4

7. variance = 1.64

standard deviation = √1.64

Step-by-step explanation:

6.  

[tex]\textsf{mean }\mu=\[ \sum [x \cdot p(x)][/tex]

⇒ [tex]\mu[/tex] = 0 x 0.4 + 1 x 0.1 + 2 x 0.2 + 3 x 0.3 = 1.4

7. see attached for completed table

[tex]\textsf{variance }\sigma^2=\[ \sum [(x -\mu)^2 \cdot p(x)][/tex]

Therefore, variance is the total of the last column:

[tex]\sigma^2[/tex] = 0.784 + 0.016 + 0.072 + 0.768 = 1.64

standard deviation is the square root of variance:

[tex]\sigma=\sqrt{1.64}[/tex]

Answer:

250m^2

Step-by-step explanation:

Area of quadrilateral = ½ × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices

We can substitute the numbers given into the formula shown above.

1/2 * 25 * (8+12)m^2

This can be simplified to 1/2 * 25 * 20 which is 250m squared

Answer: 87

Step-by-step explanation:

x - 46 = 41

x = 87

Considering that both Chicago and Memphis are in the same time zone, the flight took one hour and 40 minutes.

It Chicago at 9:50 AM Central Time and arrived in Memphis at 11:30 AM Central Time. Since they are in the same time zone, we don't have to do anything but subtract, then:

11:30 - 9:50

30 < 50, hence we remove one hour from Memphis and add 60 minutes, thus:

10:90 - 9:50 = 1:40

The flight took one hour and 40 minutes.

Linear equations are often organized in slope-intercept form:

[tex]y=mx+b[/tex]

The slope of a line is equal to its [tex]\dfrac{rise}{run}[/tex].

Typically, we would solve for the slope by using the following formula:

The y-intercept of a line refers to the y-value that occurs when x=0.

On a graph, it is the y-value where the line crosses the y-axis.

1) Determine the slope of the line (m)

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Plug in the two given points, (-17,-4) and (-7,-13):

[tex]m=\dfrac{-13-(-4)}{(-7)-(-17)}\\\\m=\dfrac{-13+4}{-7+17}\\\\m=\dfrac{-9}{10}[/tex]

Therefore, the slope of the line is [tex]-\dfrac{9}{10}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-\dfrac{9}{10}x+b[/tex]

2) Determining the y-intercept (b)

[tex]y=-\dfrac{9}{10}x+b[/tex]

Plug in one of the given points and solve for b:

[tex]-4=-\dfrac{9}{10}(-17)+b\\\\-4=\dfrac{153}{10}+b\\\\b=-\dfrac{193}{10}[/tex]

Therefore, the y-intercept of the line is [tex]-\dfrac{193}{10}[/tex]. Plug this back into our equation:

[tex]y=-\dfrac{9}{10}x-\dfrac{193}{10}[/tex]

[tex]y=-\dfrac{9}{10}x-\dfrac{193}{10}[/tex]

Using the normal distribution, it is found that P(5 ≤ x ≤ 17) = 0.6247.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, we are given that [tex]\mu = 8, \sigma = 6[/tex].

The probability is the p-value of Z when X = 17 subtracted by the p-value of Z when X = 5, hence:

X = 17:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{17 - 8}{6}[/tex]

[tex]Z = 1.5[/tex]

[tex]Z = 1.5[/tex] has a p-value of 0.9332.

X = 5:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{5 - 8}{6}[/tex]

[tex]Z = -0.5[/tex]

[tex]Z = -0.5[/tex] has a p-value of 0.3085.

0.9332 - 0.3085 = 0.6247.

Hence, P(5 ≤ x ≤ 17) = 0.6247.
