Answer:
It might be square of 13 and 14
Anyway the answer is
-13 square-14 square-1
So,
196-169-1
27-1=26 integers
6(3)-1= 17
hope this helps
First, you'd need to transform the equation into y = mx + b
To do this, set up the original equation and solve for y.
x + 5 y = -5
Subtract x from both sides.
5y = -5 - x
Now, divide by 5 into both sides to leave y on one side.
y = -1 -x/5
With this new equation, just shift the numbers on the right of y to create a y = mx + b equation
y = -x/5 - 1
Therefore, you're y intercept is -1 and you're slope is -x/5.
Hope this helps!
Recalling that SAT scores are always expressed as multiples of 10, then the points we get on the test will be 628.
<h3>What do you mean by standard deviation?</h3>
In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of population
N = number of observation of population
X = mean
μ = population mean
WE have been given that SAT scores are normally distributed, with a mean of 500 points and a standard deviation of 100 points.
The solution as follows;
Let be X: scores of SAT
P(X ≥ x) = 0.9
P((X - 500)/100 ≥ (x - 500)/100) = 0.9
P(Z ≥ z) = 0.9
z = 1.28
1.28 = (x - 500)/100
128 + 500 = x
x = 628
Recalling that SAT scores are always expressed as multiples of 10, then the points we get on the test will be 628.
