What are the three ordered pairs that should be in the table of values y=2x-3
Answer:
(-2, -7), (0, -3), (2, 1)
Step-by-step explanation:
Equation is given as y = 2x - 3.
To complete the table, plug in each value of x into y = 2x - 3 to get their corresponding y-value.
✔️When x = -2:
y = 2(-2) - 3
y = -4 - 3
y = -7
✔️When x = 0:
y = 2(0) - 3
y = -3
✔️When x = 2:
y = 2(2) - 3
y = 4 - 3
y = 1

Juan determines that a triangle has sides that measure 5 cm, 12 cm, and 13 cm. The same triangle also has one 90°° angle and two angles that are less than 90°°. Which best describes the triangle Juan is measuring?
isosceles right
scalene acute
scalene right
equilateral right
Answer:
scalene right
Step-by-step explanation:
A scalene right has no equal side lengths, has a right side(90) and will have two angles less than 90 because all three triangle sides need to equal to be 180. So scalene right is your answer. Hope that helped!

Is (x-4) a factor of x^3 +x^2 -16x-16x 3 +x 2 −16x−16 ?
Answer:
For x – 4 to be a factor, you must have x = 4 as a zero. Using this information, I'll do the synthetic division with x = 4 as the test zero on the left:

Answer:
Four (4); 45; at least; 181.
Step-by-step explanation:
Ali has four friends that owe him x dollars each. His parents owe him $45 for doing chores last week. He recalls that people owed him at least $181.
To find how much money each of Ali's friends owe him;
Given the algebraic expression;
4x + 45 ≤ 181
4x ≤ 181 - 45
4x ≤ 36
Dividing both sides by 9, we have;
x ≤ 9
Therefore, Ali's friends owe him at least $9 each.
Answer:
Four (4); 45; at least; 181.
Step-by-step explanation:

A lab is testing the amount of a certain active chemical compound in a particular drug that has been recently developed. The manufacturer claims that the average amount of the chemical is 95 mg. It is known that the standard deviation in the amount of the chemical is 5 mg. A random sample of 25 batches of the new drug is tested and found to have a sample mean concentration of 89.9 mg of the active chemical.
Calculate the 95% confidence interval for the mean amount of the active chemical in the drug. Give your answers to 2 decimal places. (suppose to be number less than and equal to mean less than and equal to another number)
Answer:
The 95% confidence interval is "87.94, 91.86".
Step-by-step explanation:
The given values are:
Sample batches,
n = 25
Sample mean concentration,
[tex]\bar{x}[/tex] = 89.9 mg
Amount of chemical,
σ = 5
α = 0.05
The critical value from Z table will be:
= [tex]Z(\frac{\alpha}{2} )[/tex]
= [tex]Z(\frac{0.05}{2} )[/tex]
= [tex]1.96[/tex]
Now,
The confidence interval will be:
= [tex]\bar{x} \pm Z(\frac{\alpha}{2} )\times \frac{\sigma}{\sqrt{n} }[/tex]
On substituting the values, we get
= [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{\sqrt{25}}[/tex]
= [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{5}[/tex]
= [tex]89.9 \pm1.96\times 1[/tex]
Lower limit will be:
= [tex]89.9 -1.96\times 1[/tex]
= [tex]87.94[/tex]
Upper limit will be:
= [tex]89.9 +1.96\times 1[/tex]
= [tex]91.86[/tex]

The way you find the answer is by multiplying the numbers (simplifying)
Canceling both of the fives and adding the two negative signs together would leave you with the product of 2
PLEASE HELP!!!! The problem is in the photo below.
Answer:
A is correct.
Step-by-step explanation:
Here, the x would represent the gallons per minute. The minutes are unknown, so it's just a variable. It can't be B either, because the addition sign would mean that the pool is being filled instead of drained.

Answer:
[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]
Step-by-step explanation:
Given [Missing]
[tex]A = (-3,4)[/tex]
[tex]B = (1,3)[/tex]
[tex]C =(3,6)[/tex]
[tex]D =(1,6)[/tex]
The first transformation: reflection across the y-axis.
The rule is: [tex](x,y)==>(-x,y)[/tex]
So:
[tex]A = (-3,4)[/tex] ==>[tex]A' = (3,4)[/tex]
[tex]B = (1,3)[/tex] ==> [tex]B' = (-1,3)[/tex]
[tex]C =(3,6)[/tex] ==> [tex]C' = (-3.6)[/tex]
[tex]D =(1,6)[/tex] ==> [tex]D' = (-1,6)[/tex]
Translation 2 units down
The rule is: [tex](x,y)==>(x,y-2)[/tex]
So:
[tex]A' = (3,4)[/tex] ==> [tex]A" =(3,4-2) =(3,2)[/tex]
[tex]B' = (-1,3)[/tex] ==> [tex]B" = (-1,3-2) = (-1,1)[/tex]
[tex]C' = (-3.6)[/tex] ==> [tex]C" = (-3,6-2) = (-3,4)[/tex]
[tex]D' = (-1,6)[/tex] ==> [tex]D" =(-1,6-2) = (-1,4)[/tex]
Hence:
[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]

Answer:
[tex] \therefore x =2[/tex]
Step-by-step explanation:
[tex] \triangle TPR \sim \triangle SQR... (given) [/tex]
[tex] \therefore \frac{TP}{SQ} = \frac{PR}{QR}[/tex]
[tex] \therefore \frac{TP}{SQ} = \frac{PQ+QR}{QR}[/tex]
[tex] \therefore \frac{3}{x} = \frac{1\frac{1}{3} +2 \frac{2}{3}}{2 \frac{2}{3}}[/tex]
[tex] \therefore \frac{3}{x} = \frac{\frac{4}{3} + \frac{8}{3}}{\frac{8}{3}}[/tex]
[tex] \therefore \frac{3}{x} = \frac{\frac{12}{3}}{\frac{8}{3}}[/tex]
[tex] \therefore \frac{3}{x} = \frac{12}{8}[/tex]
[tex] \therefore x = \frac{8\times 3}{12}[/tex]
[tex] \therefore x = \frac{24}{12}[/tex]
[tex] \therefore x =2[/tex]
A sample of 26women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.208and the equation of the regression line is ModifyingAbove y with caret equals 17.8 plus 0.940 x,where x represents height. The mean of the 26heights is 63.5in and the mean of the 26pulse rates is 77.9beats per minute. Find the best predicted pulse rate of a woman who is 71in tall.
Answer:
The pulse rate is 84.54bpm
Step-by-step explanation:
Given
[tex]\^{} y = 17.8 + 0.940x[/tex]
Required
Find [tex]\^{}y[/tex] when [tex]x = 71[/tex]
Substitute 71 for x in: [tex]\^{} y = 17.8 + 0.940x[/tex]
[tex]\^{} y = 17.8 + 0.940 * 71[/tex]
[tex]\^{} y = 17.8 + 66.74[/tex]
[tex]\^{} y = 84.54[/tex]
The pulse rate is 84.54bpm
