3. (5 points) A company wishes to estimate the mean monthly electric bill. If the standard
deviation is $400, how large a sample is required to estimate the mean electric bill to within $100
with 98% confidence?
Answer:
9.304
Step-by-step explanation:
company wishes to estimate the mean monthly electric bill. If the standard
deviation is $400, how large a sample is required to estimate the mean electric bill to within $100
with 98% confidence?
Sample size, n = (Zcritical * σ) ÷ ME
σ = standard deviation ;
ME ≥ margin of error
α = 98% ; At 98% confidence level ;Zcritical = 2.326
n ≥ (2.326 * 400) / 100
n ≥ 930.4 / 100
n ≥ 9.304
n = 10

The following data points represent the number of chicken nuggets on each family member's plate.
1,3,0, 6, ?
If the mean of the data set is 3 chicken nuggets, find the missing number of chicken nuggets.
nuggets
Answer:
The missing number of chicken nuggets is 5.
Step-by-step explanation:
To find the mean of this data set, we must add every number together, then divide the sum by how many numbers are present.
Like this,
1 + 3 + 0 + 6 = 10
10 / 4 = 2.5
There are 4 present numbers in this data set, and one is missing.
Since the only number divided by 5 that would give you a quotient of 3 is 15, the missing number is 5.
Because,
1 + 3 + 0 + 6 + 5 = 15
15 / 5 = 3
Therefore, 5 is the missing number of the data set.

Which number below is irrational?
A. 3 √ 8
B. 3√ 125
C. √ 49
D. √ 52
Answer:
D. √ 52 = 2 * √ 13 irrational
Step-by-step explanation:
A. 3 √ 8 = 2 rational
B. 3√ 125 = 5 rational
C. √ 49 = 7 rational
D. √ 52 = 2 * √ 13 irrational
Answer:
The irrational number is [tex]\sqrt{52}[/tex].
Step-by-step explanation:
An irrational number is a non-terminating decimal number that does not follow any specific pattern (example: 0.333.... and 16.111... are all repeating with 3s and 1s, making them rational. While [tex]\sqrt{3}[/tex] or [tex]\sqrt{5}[/tex] are continuing decimals without a pattern, making them irrational). [tex]\sqrt[3]{8}[/tex], [tex]\sqrt[3]{125}[/tex], and [tex]\sqrt{49}[/tex] are all rational numbers, as they are equivalent to 2, 5, and 7 respectively. [tex]\sqrt{52}[/tex] can be written as [tex]\sqrt{4*13}[/tex] or [tex]2\sqrt{13}[/tex], since [tex]\sqrt{13}[/tex] is not a complete square root, which means that [tex]2\sqrt{13}[/tex] is an irrational number.

Which ordered pair is the solution of the following
system of equations?
3x + 2y = 4
–2x + 2y = 24
A. (2, -1)
B. (2,-5)
C. (-4,8)
D. (-4,-8)
Answer:
C
Step-by-step explanation:
Given the 2 equations
3x + 2y = 4 → (1)
- 2x + 2y = 24 → (2)
Multiplying (2) by - 1 and adding to (1) will eliminate the y- term
2x - 2y = - 24 → (3)
Add (1) and (3) term by term to eliminate y
5x + 0 = - 20
5x = - 20 ( divide both sides by 5 )
x = - 4
Substitute x = - 4 into either of the 2 equations and solve for y
Substituting into (1)
3(- 4) + 2y = 4
- 12 + 2y = 4 ( add 12 to both sides )
2y = 16 ( divide both sides by 2 )
y = 8
solution is (- 4, 8 ) → C
What is the value of the expression 6 +5. (8 + 2)²?
The value of the expression 6 +5. (8 + 2)² is 506 after solving with BODMAS rule.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have an epression:
= 6 +5. (8 + 2)²
We can solve the above expression by BODMAS:
= 6 + 5(10)²
= 6 + 5(100)
= 6 + 500
= 506
Thus, the value of the expression 6 +5. (8 + 2)² is 506 after solving with BODMAS rule.

Substitute t = 3 and t = 6 to determine if the two expressions are equivalent.
3 (2 t + 5) 6 t + 15
Which statements are true? Select the three correct answers.
A. The value of both expressions when t = 3 is 33.
B. The value of both expressions when t = 3 is 23.
C. The value of both expressions when t = 6 is 41.
D. The value of both expressions when t = 6 is 51.
E. The two expressions are equivalent.
F. The two expressions are not equivalent.
Answer:
A.The value of both expressions when t=3 is 33.
D.The value of both expressions when t=6 is 51.
E.The two expressions are equivalent.
Step-by-step explanation:
We are given two expressions.
3(2t + 5)
6t + 15
Now let's find the value of these two expressions when t =3 and t = 6
When t =3, the value of the expressions:
3(2*3 + 5) = 3(6 + 5) = 3(11) = 33
6*3 + 15 = 18 + 15 = 33
So the value of both the expressions is 33 when t = 33.
When t = 6, the value of the expressions:
3(2*6 + 5) = 3(12 + 5) = 3(17) = 51
6*6 + 15 = 36 + 15 = 51
The value of both the expressions is 51 when t = 51.
So the following statements are true:
A.The value of both expressions when t=3 is 33.
D.The value of both expressions when t=6 is 51.
E.The two expressions are equivalent.

Solve the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropriate.
Answer:
Following are the responses to the given question:
Step-by-step explanation:
[tex]\angle C= 180 - ( 26 + 51 )\\\\C = 103^{\circ}[/tex]
applying the law of sines to find the unknown sides:
[tex]\to \frac{a}{\sin A} = \frac{c}{\sin C}\\\\\to \frac{a}{\sin 26} = \frac{28}{\sin 103}\\\\a=\frac{28 \times \sin 26 }{\sin 103}\\\\a=\frac{28 \times 0.438371147 }{0.974370065}\\\\a=\frac{12.2743921 }{0.974370065}\\\\a=12.597259\\\\a=12.59\\\\a = 12.6 \ m\\\\[/tex]
[tex]\to \frac{b}{\sin 51} = \frac{28}{\sin 103}\\\\\to b=\frac{28 \times \sin 51 }{\sin 103}\\\\b=\frac{28 \times 0.777145961 }{0.974370065}\\\\b=\frac{21.7600869 }{0.974370065}\\\\b=22.3324681\\\\b=22.3\\\\b = 22.3 \ m\\\\[/tex]
so,
[tex]\angle C = 103^{\circ}\\\\\to AC = 22.3\ m\\\\\\to BC = 12.6 \ m[/tex]

I believe this is the answer!
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive. Hope this helps!
A 32-foot ladder is leaning against a building and forms a 29.37° angle with the ground. How far away from the building is the base of the ladder? Round your answer to the nearest hundredth.
Answer:
27.89feet
Step-by-step explanation:
Given the following
Length of the ladder = 32foot = hypotenuse
Angle of elevation = 29.37°
Required
Distance of the building from the base of the ladder (adjacent)
Using the SOH CAH TOA identity
Cos theta = adj/hyp
Cos 29.37° = d/32
d = 32cos29.37°
d = 32(0.8715)
d = 27.89 feet
Hence the required distance is 27.89feet
Answer:
27.89 feet

Rachel's car has a 12 gallon gas tank and
she uses about 0.5 gallons per day driving to
school. Write an equation describing the
number of gallons of gas, g, Rachel has in
her car and the number of days, d, she has
driven to school.
please help meeee
Answer:
g=dx
Or, if you'r wanting the solved equation..
12 = 0.5 x 24
Step-by-step explanation:
If she has 12 gallons in her tank and you look at what it's asking us to do, "..number of gallons of gas, g" pairs up with the 12 gallons while the 0.5 gallons used per day pairs with "...the number of days, d, she has driven to school."

10) What changes when a figure is
transformed by a reflection, rotation,
or a translation?
A) its area
C) its position
B) its size
D) its perimeter
Answer:
size because when a figure is squeezed, it shrinks and changes the size
Answer:
Its Position
Step-by-step explanation:
Reflection-when the shape is reflected over an axis
Rotation-when the shape is rotated around a singular point
Translation-when the shape is moved up/down or left/right
None of these change any part of the shape it just moves the shape around. :)

7. A boy on ice skates has a momentum of 200 kg m/s to the left at a velocity of 20
m/s. How fast is the boy going?
Answer: 10 m/s
Step-by-step explanation:
Given
Momentum of boy [tex]P=200\ kg.m/s[/tex]
Mass of boy is [tex]m=20\ kg[/tex]
Momentum is the product of mass and velocity
[tex]P=mv[/tex]
Substitute value
[tex]\Rightarrow 200=20\times v\\\Rightarrow v=10\ m/s[/tex]
Thus, the boy is moving with a velocity of 10 m/s
