What is the solution to this system of linear equations?
Answer: To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect. The two lines intersect in (-3, -4) which is the solution to this system of equations.

The ages of a group of randomly selected adult females have a standard deviation of years. Assume that the ages of female statistics students have less variation than ages of females in the general population, so let years for the sample size calculation. How many female statistics student ages must be obtained in order to estimate the mean age of all female statistics students
Answer:
Assume that we want 90% confidence that the sample mean is within one-half year of the population mean. Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? The required sample size is . (Round up to the nearest whole number as needed.) Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? A. Yes, because statistics students are typically younger than people in the general population. O B. No, because there is no age difference between the population of statistics students and the general population. O C. No, because statistics students are typically older than people in the general population.

Which of the following is a monomial?
A. 9/x
B. 11x^2
C. 20x - 14
D. 20x^9 – 7x
ITS B: 11x^9
Mono (1) nomial == 1 term.
11x^2 is 1 term in combination so B is your answer.
D. is not, its a binomial along with C. and A.
Two angles are supplementary. One angle is five times larger than the other. What are the measures of the two angles.
Answer:
30 degrees ; 150 degrees
Step-by-step explanation:
1) rememeber that two supplementary angles have their sum equals to 180 degrees
2) write an equation with the given information
x + 5x = 180
2) solve the equation
- added up the terms with x
6x = 180
- divide the two members by 6
x = 30
- find the second angle by multiplying 30 by 5
150
1. When Aaron runs the 400 meter dash, his finishing times are normally distributed with a mean of 80 seconds and a standard deviation of 2.5 seconds. Using the empirical rule, determine the interval of times that represents the middle 99.7% of his finishing times in the 400 meter race.
Answer:
(72.5,87.5)
Step-by-step explanation:
The interval of times that represents the middle 99.7% of his finishing times in the 400 meter race is; (73.5, 87.5)
What is the interval from empirical rule?
We are given;
Mean; E(X) = μ = 80 seconds
Standard Deviation; σ = 2.5
From the empirical rule, the probability of obtaining values within one deviation from the mean is 0.68; within two deviations is 0.95 and within 3 deviations from the mean is 0.997.
We have 99.7 % of the values within 3 deviations from the mean in our question and so the intervals are;
μ - 3σ = 80 - 3(2.5) = 73.5
μ + 3σ = 80 + 3(2.5) = 87.5

u. can find it through phythagoras theorem
Answer:
25
Step-by-step explanation:
Use the pythagorean theorem. Here's how: Since a^2+b^2=c^2, 7^2+24^2=576+49= the square root of 625 which is 25.
The equation 150s + 45h = 1,155 is used to determine the number of skateboards s and the number of helmets h that can be bought for $1,155. You purchase 5 skateboards. Select all the steps that may be used when solving for the number of helmets purchased.
A. Multiply both sides by 45.
B. Add 150s to both sides.
C. Subtract 150s from both sides.
D. Substitute 5 for s in the equation.
E. Divide both sides by 45.
Answer:
D & E
Step-by-step explanation:
150(5)+45h=1155 D
750+45h=1155
45h=405
h=9 E

Answer: 7.5 batches
Step-by-step explanation:
60/6 is 10, so she needs to make 10 batches in total.
10-2.5=7.5
Answer:
no. of muffins = 60 muffins
no of muffins in each batch = 6 muffins
no. of batches which got over = 2.5 batches
no. of muffins baked = 6 * 2.5 = 15
no. of muffins to be baked = 60 - 15 = 45
no. of batches required to bake 45 muffins = 45 / 6 = 7.5
hope this answer helps you!
