Answer:
heyy matee...
see
Vertices (V) = 8
Faces (F) = 6
Edges (E) => F + V - E = 2 (EULER'S FORMULA)
so 6 + 8 - 2 = E => E = 12
now just look at options
and however its a common thing that if Vertices are 8 and Faces are 6 and Edges are 12 then it is cube or cuboid
and another name of cuboid is rectangular prism ;)
hence answer is option c - rectangular prism

Answer:
Value of ∠1 = 102°
Value of ∠1 = 72°
Step-by-step explanation:
Given:
∠ S = 42°
∠ A = 30°
Find:
Value of ∠1
Value of ∠2
Computation:
Using angle sum property;
Sum of all interior angle of a triangle = 180°
∠ S + ∠ A + ∠ 1 = 180
42 + 30 + ∠ 1 = 180
72 + ∠ 1 = 180
∠ 1 = 180 - 72
∠ 1 = 102
Value of ∠1 = 102°
∠ 1 and ∠ 2 makes a straight line
So,
∠ 1 + ∠ 2 = 180
102 + ∠ 2 = 180
∠ 2 = 180 - 102
∠ 2 = 72
Value of ∠1 = 72°

b. Calculate the P-value for the appropriate two-sample z test, assuming that the data was based on n = 500. (Round your answer to four decimal places.)
c. Is the small P-value for n = 500 indicative of a difference that has practical significance
Answer :
0.1574
0.00157
Yes
Step-by-step explanation:
Hypothesis :
H0 : μ1 - μ2 = 0
H1 : μ1 - μ2 ≠ 0
Given :
x1 = 60.7 ; x2 = 60.5 ; s1 = 1 ; s2 = 2
Based on n = 100
Test statistic, Z :
Z = (x1 - x2)/[√(s1²/n1 + s2²/n2 )]
x1 - x2 = 60.7 - 60.5 = 0.2
0.2 / √(1²/100 + 1²/100 )]
0.2 / √0.02
Z = 1.414
The Pvalue from Zscore :
P(Z < 1.414) = 0.1574
B.)
For n = 500
Z = (x1 - x2)/[√(s1²/n1 + s2²/n2 )]
x1 - x2 = 60.7 - 60.5 = 0.2
0.2 / √(1²/500 + 1²/500 )]
0.2 / √0.004
Z = 3.162
The Pvalue from Zscore :
P(Z < 3.162) = 0.00157
Yes, the small Pvalue for n = 500 is indicative of a difference with practical significance ; as the Pvalue are compare with the α to make about a Decison about our hypothesis.

A circle has a circumference of 113.04 units.
Answers
Answer:
The answer may or may not be either the diameter is 36 units, or the radius is 18 units.
Step-by-step explanation:
Since there is no question, then I am just assuming the question is what is the diameter or the radius. You would find this by dividing the circumference by pi:
113.04 / 3.14 = the diameter is 36
36 / 2 = the radius is 18

Answer:
(d) Both sales persons will earn a monthly salary of $5,000 for $25,000 in sales
Step-by-step explanation:
The variable definitions are ...
x = amount of sales
y = monthly earnings
Then the point (x, y) = (25000, 5000) means earnings are $5000 on sales of $25,000.

Answer:
[tex] \frac{3}{4} = \frac{9}{12} [/tex]
[tex] \frac{1}{3} = \frac{2}{6} [/tex]
[tex] \frac{2}{4} = \frac{4}{8} [/tex]
Step-by-step explanation:
To generate equivalent fractions, you can either multiply the numerator and denominator by the same number or divide the numerator and denominator by a number provided the numerator and denominator remains whole number.
Let's solve the given problem:
Problem 1:
[tex] \frac{3}{4} = \frac{x}{12} [/tex]
To find the numerator that will make the fractions equivalent, the numerator would be multiplied by the same number that was used to multiply the denominator of the first fraction (4), from which the denominator of the second fraction (12) was gotten.
Here, the denominator of the first fraction, 4, was multiplied by 3 to get the denominator of the second fraction = 12.
Therefore, the numerator of the second fraction would be gotten by multiplying the numerator of the first fraction, 3 by 3 = 9.
Thus:
[tex] \frac{3}{4} = \frac{3*3}{4*3} [/tex]
[tex] \frac{3}{4} = \frac{9}{12} [/tex]
Both fractions are now equivalent because they now have the same value. 3÷4 will give you the same value as 9÷12.
Problem 2:
[tex] \frac{1}{3} = \frac{2}{x} [/tex]
The numerator, 1, was multiplied by 2 to get 2.
Therefore:
[tex] \frac{1}{3} = \frac{1*2}{3*2} [/tex]
[tex] \frac{1}{3} = \frac{2}{6} [/tex]
Problem 3:
[tex] \frac{2}{4} = \frac{x}{y} [/tex]
We can either divide the denominator and numerator by the same number which should remain a whole number, or multiply the denominator and numerator by the same number.
Let's multiply by 2 to get am equivalent fraction.
[tex] \frac{2}{4} = \frac{2*2}{4*2} [/tex]
[tex] \frac{2}{4} = \frac{4}{8} [/tex]

What is the radius of a sphere with a volume of 1203 cm', to the nearest tenth of a
centimeter?
Answers
Answer:
The radius of the sphere is of 6.6 centimeters.
Step-by-step explanation:
Volume of an sphere:
The volume of an sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In this question:
[tex]V = 1203 \text{cm}^{3}[/tex]
Replacing into the equation, we find the radius, in centimeters. So
[tex]V = \frac{4\pi r^3}{3}[/tex]
[tex]1203 = \frac{4\pi r^3}{3}[/tex]
[tex]r^3 = \frac{1203*3}{4\pi}[/tex]
[tex]r = \sqrt[3]{\frac{1203*3}{4\pi}}[/tex]
[tex]r = 6.6[/tex]
The radius of the sphere is of 6.6 centimeters.

[tex]\sigma = 0.831[/tex] --- Standard deviation
[tex]Mode = 10[/tex]
Step-by-step explanation:
Given
[tex]x = 9,8,10,9,8,10,9,10,8,10[/tex]
Solving (a): The population standard deviation
First, we calculate the mean
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{9+8+10+9+8+10+9+10+8+10}{10}[/tex]
[tex]\bar x = \frac{91}{10}[/tex]
[tex]\bar x = 9.1[/tex]
The standard deviation is:
[tex]\sigma = \sqrt{\frac{1}{n}\sum (x - \bar x)^2}[/tex]
So, we have:
[tex]\sigma = \sqrt{\frac{1}{10}*[(9 - 9.1)^2+.................+(10- 9.1)^2]}[/tex]
[tex]\sigma = \sqrt{\frac{1}{10}*6.9}[/tex]
[tex]\sigma = \sqrt{0.69}[/tex]
[tex]\sigma = 0.831[/tex]
The mode is:
[tex]Mode = 10[/tex]

You might be able to figure this in your head as ...
3×29 +2×28 = 3×(28+1) +2×28 = 5×28 +3 = 140 +3 = 143

Find the measure of HJK
Answers
Answer:
m<HJK = 40°
Step-by-step explanation:
Given:
m<HJK = 3x - 2
m<KJL = 50°
Required:
m<HJK
Solution:
m<HJK + m<KJL = 90° (complementary angle)
Substitute
3x - 2 + 50 = 90
Add like terms
3x + 48 = 90
3x + 48 - 48 = 90 - 48
3x = 42
3x/3 = 42/3
x = 14
✅m<HJK = 3x - 2
Plug in the value of x
m<HJK = 3(14) - 2 = 42 - 2
m<HJK = 40°
