Box A contained 40 paperclips. Box B contained 23 paperclips. After Sally took an equal number of paperclips from each box, Box A then contained twice as many paperclips as Box B. How many paperclips did Sally take from each box?
Answer:
Step-by-step explanation:
Number of clips in box A = 40
Number of clips in box B = 23
If Sally took out 6 clips from each box
Remaining clips in box A = 40 - 6 = 34 which is twice of 17
Remaining clips in box B = 23 - 6 = 17
Answer:
Sally took 6 paperclips from each box
Step-by-step explanation:
Paper clips in Box A = 40
Paper clips in Box B = 23
Let the equal number paperclips removed from each box = x
Number of clips in box A after taking 'x' clips = 40 -x
Number of clips in box B after taking 'x' clips = 23 -x
40 - x = 2*(23 -x)
40 - x = 2*23 - 2*x
40 -x = 46 - 2x {Add 2x to both sides}
40 - x + 2x = 46 {Combine like terms}
40 + x = 46 {Subtract 40 form both sides }
x = 46 - 40
x = 6
Sally took 6 paperclips from each box
Now assume a 95% confidence level. Without performing any calculations, complete the sentence below. The margin of error for a 95% confidence level will be
Answer: greater than 0.3
Step-by-step explanation:
On edge
The margin of error for a 95% confidence level will be greater than 0.3.
What is a confidence interval?A random population parameter is likely to be included in a confidence interval, which is a range of values that is limited by the statistic's mean. The confidence level is the percentage of probability, or certainty, that, after repeated random sample draws, the confidence interval would include the true population parameter.
Given:
A confidence level is 95%.
The formula to calculate the margin of error:
The margin of error = Z x S/√n.
Where S is the standard deviation and n is the sample size.
The corresponding z-score of the confidence level is 95%.
So, the margin of error will be always greater than 0.3.
Therefore, the margin of error will be always greater than 0.3.

PLEASE HELP ME!! A: Given that the triangles are similar, find the length of side KL
In ΔQRS, s = 2.3 inches, ∠S=51° and ∠Q=44°. Find the area of ΔQRS, to the nearest 10th of an square inch.
Answer:
Area of ΔQRS = 2.3 square inches
Step-by-step explanation:
From the given information,
<S + <Q + <R = [tex]180^{o}[/tex]
51 + 44 + <R = [tex]180^{o}[/tex]
95 + <R = [tex]180^{o}[/tex]
<R = [tex]180^{o}[/tex] - 95
= [tex]85^{o}[/tex]
<R = [tex]85^{o}[/tex]
Applying the Sine rule, we have;
[tex]\frac{q}{SinQ}[/tex] = [tex]\frac{r}{SinR}[/tex] = [tex]\frac{s}{SinS}[/tex]
Using [tex]\frac{r}{SinR}[/tex] = [tex]\frac{s}{SinS}[/tex]
[tex]\frac{r}{Sin 85}[/tex] = [tex]\frac{2.3}{Sin51}[/tex]
r = [tex]\frac{2.3*Sin85}{sin51}[/tex]
= 2.9483
r = 2.9 inches
Also, [tex]\frac{q}{SinQ}[/tex] = [tex]\frac{s}{SinS}[/tex]
[tex]\frac{q}{Sin44}[/tex] = [tex]\frac{2.3}{Sin51}[/tex]
q = [tex]\frac{2.3*Sin44}{Sin51}[/tex]
= 2.0559
q = 2.0 inches
From Herons formula,
Area of a triangle = [tex]\sqrt{s(s-q)(s-r)(s-s)}[/tex]
s = [tex]\frac{2.3 + 2.0 + 2.9}{2}[/tex]
= 3.6
Area of ΔQRS = [tex]\sqrt{3.6(3.6-2.0(3.6-2.9)(3.6-2.3)}[/tex]
= 2.2895
Area of ΔQRS = 2.3 square inches

The following triangles are similar. Solve for x:
Answer:
5
Step-by-step explanation:
Common factor: 4. Divide 20 by 4 to get 5
Answer: X=5
Step-by-step explanation:
Since the triangles are similar shape-wise, then that means that the sides are going to be similar numerically.
12/4 got us 3, which is the side of that smaller triangle. Since we divided 12 by 4, then we need to divide 20 by 4 to get the unknown side. 20/4 is 5, therefore x is 5.
A high school booster club is selling raffle tickets for three different prizes. The tickets are $1 for the small prize, $2 for the medium prize, and $5 for the large prize. Shiloh spent $35 on 15 tickets. Together, the number of $2 and $5 tickets she bought is 1 more than the number of $1 tickets she bought. If x represents the number of $1 tickets, y represents the number of $2 tickets, and z represents the number of $5 tickets Shiloh bought, which system of equations represents this situation?
Answer:
x+y+z=15
x+2y+5z=15
-x+y+z=1
Step-by-step explanation:
Answer:
The answer is
x + y + z = 15
x + 2y + 5z = 35

A survey is being conducted to decide on how much time people spend watching sports on television. Tell whether the given sample is biased or unbiased. Explain your answers. (NOT A MULTIPLE CHOICE)
1. Every fifth person who enters Little Casesars Arena for a Red Wings game
2. Every tenth name in the phone.
Sampling bias occurs when some members of a population are systematically more likely to be selected in a sample than others. From this definition,
For sample 1, Every fifth person who enters Little Casesars Arena for a Red Wings game. This is not biased because no person is more likely to be selected than another
For sample 2, Every tenth name in the phone. This is also not biased
because no person is more likely to be selected than another

Hello There!
Remember this is the triangle angle rule:
The angles of a triangle MUST have a sum of 180
That being said we can find the missing angle by subtracting the given angles ( 87 and 32 in this case) from 180
so missing angle = 180 - 87 - 32
180 - 87 = 93
93 - 32 = 61
so we can conclude that the answer is c
