Answer:
871.5
Step-by-step explanation:
directly proportional
y = kx
y = 12 when x = 14
12 = k(14)
k = 12/14
k = 6/7
--------------------------
what is the value of x when y = 747
747 = (6/7) * x
Multiply both sides by 7/6
747 * 7/6 = x
871.5 = x

the line ab has midpoint (-2,4). a has coordinates (3,-2). find the coordinates of b
Answer:
B = (-7,10)
Step-by-step explanation:
Given that , a line AB has midpoint (-2,4) and the coordinates of A is ( 3 , -2). We need to find out the coordinates of B .
Let coordinate of B be ( p,q ). We can use midpoint formula , as ,=> Midpoint = ( x₁ + x₂ / 2 , y₁ + y₂/2 )
=> ( -2,4 ) = ( p + 3)/2 , ( q -2 )/2
On comparing ,=> -2 = p + 3/2
=> p + 3 = -4
=> p = -3 - 4
=> p = (-7)
Also :-
=> q - 2/2 = 4
=> q -2 = 8
=> q = 8 + 2
=> q = 10
Hence the coordinates of B is ( -7,10 ) .HELPPPP MEEEEEEE PLZZZZZZ

Answer:
Let us first jot down all the data given in the question;
Number of low quality computers (LQ) = 72
Number of medium quality computers (MQ) = 112
Number of high quality computers (HQ) = 711
∴ Total number of computers found in a random sample = 72 + 112 + 711 = 895.
∴ To find the probability of purchase for each category of computers, we use the following formula;
So,
P(LQ) = 72/895 = 0.08
P(MQ) = 112/895 = 0.125
P(HQ) = 711/895 = 0.794
Ans) Probability of purchase of a low quality computer, a medium quality computer, and a high quality computer are 0.08, 0.125, and 0.794 respectively

Answer:
316.2 m/s
Step-by-step explanation:
What the problem statement doesn't tell you is that the value of m in the formula must have units of kilograms. 17 grams is 0.017 kilograms, so the velocity is ...
[tex]v=\sqrt{\dfrac{2K}{m}}=\sqrt{\dfrac{2(850)\text{ J}}{0.017\text{ kg}}}=\sqrt{100\,000}\text{ m/s}\approx316.2\text{ m/s}[/tex]
_____
Additional comment
If you simply put the numbers into the formula without regard to correct units, you might be led to believe the velocity is 10 m/s. That would be the speed of a 17 kg object with an energy of 850 J.

A research firm needs to estimate within 3% the proportion of junior executives leaving large manufacturing companies within three years. A 0.95 degree of confidence is to be used. Several years ago, a study revealed that 35% of junior executives left their company within three years. To update this study, how many junior executives should be surveyed
Answer:
972 junior executives should be surveyed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
35% of junior executives left their company within three years.
This means that [tex]\pi = 0.35[/tex]
0.95 = 95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
To update this study, how many junior executives should be surveyed?
Within 3% of the proportion, which means that this is n for which M = 0.03. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.96\sqrt{\frac{0.35*0.65}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.96\sqrt{0.35*0.65}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.35*0.65}}{0.03}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.35*0.65}}{0.03})^2[/tex]
[tex]n = 971.2[/tex]
Rounding up:
972 junior executives should be surveyed.

Makayla goes bowling.
She has $25.00 to spend.
She spends $4.25 to rent shoes.
She spends $2.50 for each game he bowls.
Which inequality can Makayla use to determine x, the greatest number of games he can bowl?
A) 2.5 +4.25x > 25
B 4.25 + 2.5x > 25
2.5 + 4.25x < 25
D 4.25 +2.5x < 25
Answer:
4.25 + 2.50x < 25
Step-by-step explanation:
Makayla can't spend more than $25 and you pay an initial fee of 4.25 for the shoes and 2.50 for each game so the inequality would be
D.) $4.25 + 2.50x < 25.
A line passes through the points A and B, whose coordinates are A(5, -5) and B(-10, -11). What is the equation of the line? The equation is given by Ax + Bx = C.
Answer:
Step-by-step explanation:
the instruction say put it in this form Ax +Bx = C , but i'm sure they were meant to say this Ax +By = C note the X and Y differences. I'll use the latter form, b/c that's the "standard" form
find the slope:
m = -11 - (-5) / -10-5
m = -11 + 5 / -15
m = -6 / -15
m = 2/5
y-(-5) = 2/5(x-5)
y + 5 = 2x/5 -2
y = [tex]\frac{2}{5}[/tex] x - 7
- [tex]\frac{2}{5}[/tex] x +y = -7
