25x + 15y=17
25x + 15y=305$
Neee answer ASAP
Answer:
1st. Problem
Let's solve for x.
25x+15y=17
Step 1: Add -15y to both sides.
25x+15y+−15y=17+−15y
25x=−15y+17
Step 2: Divide both sides by 25.
25x/25 = -15y+17/ 25
x equals...
x= -3/5 y + 17/25
2nd. Problem
Let's solve for x.
25x+15y=305
Step 1: Add -15y to both sides.
25x+15y+−15y=305+−15y
25x=−15y+305
Step 2: Divide both sides by 25.
25zx/25 = -15y305/25
x equals...
x = -3/5 y + 61/5

For a normal distribution, what z-score value separates the lowest 25% of the scores from the rest of the distribution
Answer:
Z = -0.675.
Step-by-step explanation:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
What z-score value separates the lowest 25% of the scores from the rest of the distribution
This is Z which has a pvalue of 0.75, so Z = -0.675.

Find the equation of a line perpendicular to y=-3x-1 that contains the point (-1,1). Write the equation in slope intercept form.
Answer:
y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
y = -3x - 1
1. Perpendicular line needs the opposite (reciprocal) of the slope.
reciprocal of -3 is -1/3, slope 1/3. y = 1/3x + b
2. Now find the b (y-intercept). 1 = 1/3(-1) + b
1 = -1/3 + b
+ 1/3 +1/3
1 1/3 = b
3. Answer y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]

Find m\angle Am∠Am, angle, A.
Round to the nearest degree.
Answer:
m∠A = 106°
Step-by-step explanation:
All three sides of the triangle are given in the question.
To find the measure of included angle A between two sides we will apply cosine formula,
BC²= AB² + AC² - 2(AB)(AC)cosA
(13)² = (10)² + (6)² - 2(10)(6)cosA
169 = 100 + 36 - 120cosA
cosA = [tex]\frac{-169+136}{120}[/tex]
cosA = -0.275
A = [tex]\text{cos}^{-1}(-0.275)[/tex]
A = 105.96°
A ≈ 106°
Therefore, m∠A = 106° will be the answer.
Convert each of mixed number to an improper fraction
Answer:
Top, a through d:
A) 23/8
B) 29/6
C) 23/3
D) 16/5
Step-by-step explanation:
To make the proper fraction improper, first, multiply the whole number by the bottom number in the fraction, then add whatever number was on top of the fraction, so for A, multiply 2 (whole number) by 8 (number on the bottom of the fraction), then add 7 (number on top of the fraction)
Find the slope of the line parallel to the line with the given information:

A.2 and 3
B.3 and 4
C.4.5 and 5.5
D.9 and 10
Answer:
A. 2 and 3
Step-by-step explanation:
The square root of 7 is 2.7 which makes it between 2 and 3.
Answer:
A
Step-by-step explanation:
because the square root of 4 is 2
and the square root of 9 is 3
since 7 is in between 4 and 9 the square root is in between 2 and 3

90 divided by 3 + ( 3 - 2 ) - 20.
Answer:
11
Step-by-step explanation:
first 3-2=1 the divide 90 by 3 then add the 1 the subtract that by 20 and you will get 11
The result of the expression 90 divided by 3 plus the quantity (3 minus 2) minus 20 is 11.
To evaluate the expression 90 divided by 3 + (3 - 2) - 20, we can follow the order of operations (also known as PEMDAS/BODMAS), which stands for Parentheses/Brackets, Order/Exponents, Division/Multiplication, and Addition/Subtraction:
First, let's simplify the expression within the parentheses:
3 - 2 = 1
Now we can substitute the simplified expression back into the main expression:
90 ÷ 3 + 1 - 20
Next, perform the division:
90 ÷ 3 = 30
Now we have:
30 + 1 - 20
Next, perform the addition:
30 + 1 = 31
Finally, perform the subtraction:
31 - 20 = 11
Therefore, the value of the expression 90 divided by 3 + (3 - 2) - 20 is 11.

Sydney simplifies the expression 2csc(-y) with the work below. What did she do wrong? 2csc(x+y)= 2/sin(x-y)
=2/cos x cos(-y)+sin xsin(-y)
=2/cos x cos y - sin xsin y
=2/cos( x +y)
= 2 sec (x + y)
Answer:
We know that:
csc(x) = 1/sin(x)
Now we want to work with:
2csc(x+y)
The first step is:
2csc(x+y)= 2/sin(x-y)
This is correct so far.
Now we need to use the relation:
sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)
Then:
sin(x - y) = sin(x)*cos(-y) + sin(-y)*cos(x)
sin(x) is an odd function, then: sin(-y) = -sin(y)
and cos(x) is an even function, then:
cos(-y) = cos(y)
Then we get:
sin(x - y) = sin(x)*cos(y) - sin(y)*cos(x)
then:
2/sin(x-y) = 2/(sin(x)*cos(y) - sin(y)*cos(x))
Now let's look at what she did:
2/sin(x-y) = 2/(cos x cos(-y)+sin xsin(-y))
Here is her error, she replaced:
sin(x - y) by cos x cos(-y)+sin(x)sin(-y)
This relation is for the cosine function, not the sine one, so here is her mistake.

[tex]sin(\alpha -\beta )\neq cos \alpha[/tex] [tex]cos\beta +sin\alpha[/tex] [tex]sin\beta[/tex]
