Answer:
The is no significant evidence to conclude that mean is greater than 22
Step-by-step explanation:
H0 : μ = 22
H0 : μ > 22
The test statistic :
(xbar - μ) ÷ (σ/sqrt(n))
xbar = 22.3 ; n = 36 ; μ = 22 ; σ = 3.7
(22.3 - 22) ÷ (3.7/√36)
0.3 ÷ 0.6166666
Test statistic = 0.486
The Pvalue using a Pvalue calculator from Zscore is :
Pvalue = 0.313
α = 0.05
Pvalue > α ; We fail to reject the Null ; The is no significant evidence to conclude that mean is greater than 22
A cylinder has a height of 1.2 cm and the following base. 5 mm
What is the volume of the cylinder in cubic millimeters?
94.2 mm 3
376.8 mm 3
942 mm 3
37.68 mm 3
Step-by-step explanation:
this picture will help
you
Answer:
942 mm 3
Step-by-step explanation:
Since 1.2 cm isn't mm we have to convert that, which will be 12. now we do the formula, which is
V=3.14 x r2 x h
and when we plug in the numbers,
V=3.14 x 25 (5x5) x 12
which is 942

Estimate the line of best fit using two points on the line.
(5, 60)
(3, 44)
O A. y= 5x + 20
O B. y = -5x + 16
O C. y= -8x + 16
D. y = 8x+ 20
The estimated equation of line is y = 8x+ 20
What is linear equation?
A linear equation is defined as an equation in which the highest power of the variable is always one.
Two points on the line (5, 60), (3, 44)
[tex]y- y_1= \frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
[tex]y- 60 = \frac{60-44}{5-3} (x-5)[/tex]
[tex]y- 60 = \frac{16}{2} (x-5)[/tex]
[tex]y = 8 (x-5)+ 60[/tex]
[tex]y = 8x+ 20[/tex]
Hence, the estimated equation of line is y = 8x+ 20

Using graphing technology:
1) Graph y=x^2, and then experiment with adding different linear terms (for example, x^2 +4x, x^2+20x,x^2- 50x). Record your observations.
2) Graph y=-x^2, and then experiment with adding different linear terms. Record your observations.
Use your observations to help you complete the table without graphing the equations.

Some quadratic expressions have no linear terms. Find the x-intercepts and the x-coordinate of the vertex of the graph representing each equation. (Note it is possible for the graph to not intersect the x-axis.) If you get stuck, try graphing the equations.

Write an exponential function in the form y=ab^xy=ab x that goes through points (0,8) and (2,288)
Answer:
y = 8•6^x
Step-by-step explanation:
Here, we want to write an exponential equation
To fully write this, we need the values of a and b
From the first coordinates given;
8 = a•b^0
a = 8 since b^0 = 1
Furthermore;
288 = 8•b*2
b^2 = 36
b = √36
b = 6
So we have ;
y = 8•6^x

Shinji started with angle ∠ABC and constructed ray BE
Answer:
A and C
Step-by-step explanation:
Statements B) BA ≅ BC and C) AE ≅ DE guarantee that ray BE bisects angle ABC.
Statement B states that BA is congruent to BC. This means that side AB is the same length as side BC. Since the bisector of an angle divides the opposite side into two segments with equal lengths, this guarantees that ray BE bisects angle ABC.
Statement C states that AE is congruent to DE. This means that the segments AE and DE have the same length. Since the bisector of an angle divides the opposite side into two segments with equal lengths, this guarantees that ray BE bisects angle ABC.
The other statements are not sufficient to guarantee that ray BE bisects angle ABC. For example, if BA is congruent to BD, this does not mean that the segments AE and DE have the same length. Similarly, if BD is congruent to DE, this does not mean that side AB is the same length as side BC.
Therefore, the correct answers are B and C.

The points N, O, P and Q all lie on the same line segment, in that order, such
that the ratio of NO: OP: PQ is equal to 5: 2 : 1. If NQ = 24, find NO.
Answer:
NO= 15
Step-by-step explanation:
let 5x, 2x and x be the ratio.
5x + 2x + x = 24
8x = 24
x= 24/8 = 3
Now,
NO= 5x = 5×3 = 15
Question 15 of 40
For which sample size (n) and sample proportion () can a normal curve be
used to approximate the sampling distribution?
O A. n = 28; = 0.3
O B. n = 28; p = 0.9
O c. n = 32; p = 0.4
O D. n = 32; p = 0.2
Answer:
Option C: n = 32; p^ = 0.4
Step-by-step explanation:
The normal curve can be used in this case if; np ≥ 10 or n(1 - p) ≥ 10
A) For n = 28 and p = 0.3;
np = 28 × 0.3 = 8.4 < 10
Thus, it can't be used.
B) For n = 28 and p = 0.9;
np = 28 × 0.9 = 25.2 > 10 Ok
n(1 - p) = 28(1 - 0.9) = 2.8 Not Ok
Thus, it can't be used
C) For n = 32 and p = 0.4
np = 32 × 0.4 = 12.8 > 10 Ok
n(1 - p) = 32(1 - 0.4) = 19.2 > 10 Ok
Thus, it can be used
D) For n = 32 and p = 0.2
np = 32 × 0.2 = 6.4 < 10 Not Ok
Thus it can't be used.

Answer:
200 square yards
Step-by-step explanation:
Surface area for this will be the triangle base area x 2 added to the side areas
Side areas are 11 x 5, 11 x 5, and 11 x 6 = 55 + 55 + 66 = 176 square yards
Triangle area = 1/2 (base)(height)
= 1/2(6)(4)
= 1/2(24)
= 12.
But we have two triangles, so 12 x 2 = 24.
Add the sides to the bases: 24 + 176 = 200 square yards for the surface area.
