Answer:
Decision rule
Reject null hypothesis
Conclusion
There is significance evidence that the true mean is different from 0.86
Step-by-step explanation:
From the question we are told that
The population mean [tex]\mu = 0.86[/tex]
The sample is mean is [tex]\= x = 0.8708[/tex]
The standard deviation is [tex]\sigma = 0.0068[/tex]
The level of significance is [tex]\alpha = 0.01[/tex]
The sample size n = 3
The null hypothesis is [tex]\mu = 0.86[/tex]
The alternative hypothesis is [tex]\mu \ne 0.86[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\= x - \mu }{ \frac{\sigma}{\sqrt{n} } }[/tex]
=> [tex]z = \frac{ 0.8708 - 0.86 }{ \frac{0.0068}{\sqrt{3} } }[/tex]
=> [tex]z = 2.751 [/tex]
Generally p- value is mathematically represented as
[tex]p-value = 2 P(z >2.751 )[/tex]
From the z-table
[tex]P(z >2.751 ) = 0.0029707[/tex]
So
[tex]p-value = 2 * 0.0029707[/tex]
=> [tex]p-value = 0.00594 [/tex]
From the obtained question we see that [tex]p-value < \alpha[/tex]
Hence we reject the null hypothesis

Mrs. Johnson wants to order pizza for her students. There are 21 students in her class Her goal was for each student to get 1/5 of a pizza. How many pizza's does she need to order?
Answer:
5 and she will have 4/5 remaining.
Step-by-step explanation:
If you multiply the 5 slices per pizza by 4 pizza's you would be able to feed 20 students. Since her goal is to make sure EACH student gets 1/5 of a pizza she would need to order another one. So she needs to purchase 5 pizzas and would have 4 slices remaining.
(She could always eat those by herself or give them to me lol)
Hope that helps and have a great day!
Answer:
Mrs. Johnson need to order 5 pizzas.
Step-by-step explanation:
1. If you do 5, 10, 15, 20 that’s four
2. it’s not fair to leave one kid out so she needs to order 5 pizzas

use matrices to determine the coordinates of the vertices of the translated figure. Triangle DEF with vertex matrix [7 -9 -1 -7 -3 -7] translated 1 unites left and 4 units down.
Answer:
(6, -11), (-10, -7) and (-2, -11)
Step-by-step explanation:
Coordinates of a triangle are represented in the form of a matrix as,
[tex]\begin{bmatrix}x_1 & x_2 & x_3\\ y_1 & y_2 & y_3\end{bmatrix}[/tex]
If the given triangle is shifted by 1 unit left and 4 units down,
Translation of vertices in the matrix form will be,
[tex]\begin{bmatrix}x_1 & x_2 & x_3\\ y_1 & y_2 & y_3\end{bmatrix}+\begin{bmatrix}-1 & -1 & -1\\ -4 & -4 & -4\end{bmatrix}[/tex]
For a triangle having vertices (7, -7), (-9, -3) and (-1, -7) when shifted 1 units left and 4 units down will be,
[tex]\begin{bmatrix}7 & -9 & -1\\ -7 & -3 & -7\end{bmatrix}+\begin{bmatrix}-1 & -1 & -1\\ -4 & -4 & -4\end{bmatrix}[/tex]
= [tex]\begin{bmatrix}7-1 & -9-1 & -1-1\\ -7-4 & -3-4 & -7-4\end{bmatrix}[/tex]
= [tex]\begin{bmatrix}6 & -10 & -2\\ -11 & -7 & -11\end{bmatrix}[/tex]
Coordinates of the triangle after the translation will be,
(6, -11), (-10, -7) and (-2, -11)
Maria took a taxicab from her home to the theater
downtown. The taxicab company charges a flat fee of $5.00
plus $0.25 per mile. Which equation represents C, the total
cost of her ride, in terms of m, the length of the trip in
miles?
Answer:
The answer is the third option, C = 5 + 0.25m
Step-by-step explanation:
We already know that the official price for the taxi is 5 dollars, so we aren't multiplying that value by anything.
However, the text mentions that for each mile, Maria is taxed an extra .25 cents. Therefore, you have to add the base amount, 5, plus the 25cent with the m next to it to symbolize that however many miles she goes, the 25 cents will be multiplied by that value.

The right arrow symbol used to show the transition from a point to its image after a transformation is not contained within the Equation Editor. If such a symbol is needed, type "RightArrow." For example: P(0, 0) RightArrow P′(1, 2).
Triangle ABC has coordinates
A (1,4);B(3,−2); and C(4,2).
Find the coordinates of the image
A'B'C' after a reflection over the x-axis.
Given:
Vertices of triangle ABC are A (1,4), B(3,−2) and C(4,2).
Triangle ABC reflected over the x-axis to get the triangle A'B'C'.
To find:
The coordinates of the image A'B'C'.
Solution:
If a figure reflected over the x-axis, then rule of transformation is
[tex](x,y)\to (x,-y)[/tex]
Now, using this rule, we get
[tex]A(1,4)\to A'(1,-4)[/tex]
[tex]B(3,-2)\to B'(3,2)[/tex]
[tex]C(4,2)\to C'(4,-2)[/tex]
Therefore, the coordinates of the image A'B'C' after a reflection over the x-axis are A'(1,-4), B'(3,2) and C'(4,-2).

An expression is defined as a set of numbers, variables, and mathematical operations. The given expression [6 + √(-64)] [3 - √-16] when simplified is equal to 50.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
What is a complex number?A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit, and satisfies the equation i² = -1; every complex number may be represented as a + bi, where a and b are real numbers.
The given expression can be written as,
[6 + √(-64)] [3 - √-16]
= (6 + 8i)(3 - 4i)
= 18 - 24i + 24i - 32i²
= 18 - 32(-1)
= 18 + 32
= 50
Hence, The given expression [6 + √(-64)] [3 - √-16] when simplified is equal to 50.
