Answer:
Alyssa can be 95% sure that her next measurement will fall between the values of 9.59 and 9.91 meters per second.
Step-by-step explanation:
I just took the test and got it right
The 95% measurement will fall between 9.59 m/s and 9.91 m/s
Given;
the mean of the normal distribution, m = 9.75 m/s
standard deviation from the mean, d = 0.08 m/s
To find:
the range of Alyssa's 95% data
let this range = X
The 95% of the data will fall within 2 standard deviation below and the above the mean.
2 standard deviation below the mean = m - 2d
2 standard deviations above the mean = m + 2d
From the given values, m - 2d = 9.75 - 2(0.08) = 9.59 m/s
m + 2d = 9.75 + 2(0.08) = 9.91 m/s
Thus, the range of the 95% data = 9.59 m/s < X < 9.91 m/s

Explain how to evaluate (-9)(-6)(15)(-7+7) as simply as possible.
Answer:
For this case we must explain how to simplify the following expression:
( -9)(-6)(15)(-7+7)
According to the PEMDAS algebraic resolution order method, operations within parentheses must be performed first.
So, we have:
-7+7
Different signs are subtracted and the major sign is placed.
-7+7=0
Rewriting the original expression we have:
(-9)(-6)(15)(0)=
Every number multiplied by "0" results in "0".
Then, the expression is zero.
(-9)(-6)(15)=0
Answer:
(-9)(-6)(15)(-7+7)=0

87 = w
The width is 87 cm
Answer:
Step-by-step explanation:
Given
The area of a rectangular painting=8613 cm^2
Length of painting=99cm
Solution
Area of the rectangular painting=8613
Length×width=8613
99×width=8613
Width=8613/99

X intercepts are when y = 0, set the equation equal to zero and solve:
0 = -x^3 +x^2 + x -1
-x^3 + x^2 = -x
-x + x = 0
0-1 = -1
The first one is (-1,0)
Because the equation contains squares the answer could also be opposite, so the other answer would be (1,0)
The two answers are (-1,0) (1,0)

What is unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A unit rate is a rate in which.....
Now, if we find the unit rate of any quantity it tells that the price of 1 quantity.

Find the equation of the linear function represented by the table below in slope intercept form
Answer:
the slope is "1"
the y-intercept is "5"
y = x + 5
Step-by-step explanation:
In order to find the slope, we use the slope formula with any pair of points, for example: (1, 6) and (3, 8):
slope = (y2-y1) / (x2 - x1)
in our case:
slope = (8 - 6) / (3 - 1) = 2/2 = 1
then the slope is "1".
Now we write the general "slope-intercept" equation of a line using the slope we found:
y = m x + b
y = 1 x + b
and now use one of the points (for example (3, 8) to find the intercept "b":
(8) = 1 (3) + b
8 - 3 = b
b = 5 (y intercept)
Then the equation of the line can be written as:
y = x + 5
