Rewrite using the Distributive Property and GCF 13+36
Answer:
Step-by-step explanation:
13 and 36 have no common factor except 1.
Perhaps you meant that the 13 should be 12. In that case
GCF
12 = 2*2*336 = 2*2 *3 * 3The greatest common factor is 2 * 2 * 3
If there is a number that is not bolded, it is what is left behind inside the backets the distributive property creates.
Answer: 12(1 + 3)
Note: the 1 is part of the answer inside the brackets when one of the numbers inside the brackets and the GCF are the same

Answer:
1.64
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
6.6^2 + x^2 = 6.8^2
43.56+x^2=46.24
Subtract 43.56 from each side
x^2 = 46.24-43.56
x^2 =2.68
Take the square root of each side
sqrt(x^2) = sqrt(2.68)
x =1.637080554
To 3 significant digits
x = 1.64
Answer:
Step-by-step explanation:
x = 1.637 mm
Pythagorean theorem:We can use Pythagorean theorem, to find the unknown side for a right angled triangle.
The side opposite to 90 is the longest side and it is the hypotenuse.
Base² + altitude² = hypotenuse²
x² + 6.6² = 6.8²
x² + 43.56 = 46.24
x² = 46.24 - 43.56
x² = 2.68
x = √2.68
[tex]\sf \boxed{\bf x = 1.637 \ mm }[/tex]

A mathematics teacher wanted to see the correlation between test scores and homework. The homework grade (x) and test grade (y) are given in the accompanying table. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest tenth. Using this equation, find the projected test grade, to the nearest integer, for a student with a homework grade of 72.
There was a missing data point in the Homework Grade. So I put a 74 to get 8 data points on each variable.
Put these data points in Excel. In the Data Analysis tab, scroll down and click on Regression. Input Y range for Test Grade and Input X range for Homework Grade.
y = -0.4x + 98.3
What is the correlation?
correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data.
When you increase your homework score by 1 point, you lose 0.4 points on your test.
-0.4x + 98.3 = 74
→ -0.4x = -24.3
→ x = 60.75 ≈ 61
A student will earn a 61 on his/her homework if he/she earns a 74 on an exam.

This season, the probability that the Yankees will win a game is 0.52 and the
probability that the Yankees will score 5 or more runs in a game is 0.53. The
probability that the Yankees lose and score fewer than 5 runs is 0.39. What is the
probability that the Yankees will lose when they score 5 or more runs?
Answer:
The probability of scoring fewer than 5 runs when they win is P = 0.19
How to find the probability?
We know that:
The probability of winning a game is p = 0.53
The probability of scoring 5 or more runs is q = 0.59
The probability of winning and scoring 5 or more runs is k = 0.43
Notice that the joint probability is different than the product of the individual probabilities, this means that the events are not independent.
So, we know that the probability of winning is 0.53
Now, given that they win, the probability of scoring 5 or more times will be q' such that:
0.53*q' = 0.43
q' = 0.811
This means that when they win, the probability of scoring more than 5 times is 0.81
Then the probability of scoring less than 5 times when they win is 1 minus the above probability:
P = 1 - 0.81 = 0.19
The probability of scoring fewer than 5 runs when they win is P = 0.19
The equation of a line is given below. =−4x3y−3 Find the slope and the y-intercept. Then use them to graph the line.
The slope of the line is the negative 4/3 and y-intercept will be the negative 1.
The correct equation is given below.
−4x − 3y = 3
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The equation of the line will be
−4x − 3y = 3
Then the equation of a line can be written as
4x + 3y = −3
3y = −4x − 3
y = −(4/3)x − 1
Then the slope of the line is the negative 4/3 and y-intercept will be the negative 1.
The graph is given below.
