The histogram shows the ages of people in a community chorus. How many people in the chorus are 50 or older? Enter your answer in the box.
Answer:
13
Step-by-step explanation:
The computation of the number of people in the chorus are 50 or older is as follows
According to the attached figure
In the age of 50 - 60 , there is 8 people
In the age of 60 - 70 , there is 4 people
In the age of 70 -80, there is 1 people
So, if we do the total that comes
= 8 people + 4 people + 1 people
= 13 people
Hence, the no of people would be 13

Of the last 14 contestants on a game show, 7 qualified for the bonus round. Considering this data, how many of the next 10 contestants would you expect to qualify for the bonus round?
a. 7/10
b. 3/7
c. 1/2
d. 1/3
Answer:
c. 1/2
Step-by-step explanation:
7 out of 14 contestants did last time, which is 1/2 of the contestants. You would assume that the same proportion would qualify when there are 10 contestants, so you would assume that 1/2 of 10 would also qualify for the bonus round.

Step-by-step explanation:
where k is the constant of variation. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10. ... Thus, the equation describing this inverse variation is xy = 10 or y = .

What are the factors of the expression x^2+x-20?
Answer:
(x-4)(x+5)
Step-by-step explanation:
Find 2 numbers knowing sum (1) and product (-20). To find them, factor pairs of (-20) --> (-2,10) (-4,5). This sum is 1=b. Then, these 2 numbers are: - 4 and 5. Y=(x-4) (x+5). Hope this helped :)

Helppp law of sines and law of cosines
Answer:
[tex]\displaystyle ST ≈ 15,9\\ RT ≈ 30,8 \\ m∠S = 111°[/tex]
Step-by-step explanation:
First off, find [tex]\displaystyle m∠S:[/tex]
[tex]\displaystyle 180° = 58° + 31° + m∠S → 180° = 89° + m∠S \\ 111° = m∠S[/tex]
Now that the third angle has been defined, we can move move forward with solving for a second edge, using the Law of Sines, but before proceeding, here are some things you should know about this triangle:
Edge s [RT] → [tex]\displaystyle m∠S[/tex]Edge t [RS] → [tex]\displaystyle m∠T[/tex]Edge r [ST] → [tex]\displaystyle m∠R[/tex]Now that we have the information, we can proceed with the process:
[tex]\displaystyle \frac{t}{sin∠T} = \frac{s}{sin∠S} = \frac{r}{sin∠R} \\ \\ \frac{28}{sin\:58°} = \frac{s}{sin\:111°} → \frac{28sin\:111°}{sin\:58°} → 30,82402055... = s \\ 30,8 ≈ s[/tex]
_______________________________________________
Now that RT has been defined, we can now proceed to solving the third edge, using the Law of Cosines:
[tex]\displaystyle s^2 + r^2 - 2sr\: cos∠T = t^2 \\ t^2 + r^2 - 2tr\: cos∠S = s^2 \\ t^2 + s^2 - 2ts\: cos∠R = r^2 \\ \\ 28^2 + 30,8^2 - 2[28][30]\: cos\:31° = r^2 → 784 + 948,64 - 1680\: cos\:31° = r^2 → \sqrt{254,1978397...} = \sqrt{r^2} → 15,94358303... = r \\ 15,9 ≈ r[/tex]
Your triangle is now complete!
I am joyous to assist you at any time.
Answer:
Step-by-step explanation:
In this case, you would use law of sines due due you being given two angles and one side.
LAW OF ANGLES IN TRIANGLES: 180 - a - b = c
So in this case: 180 - 31 - 58 = m<S = 91
LAW OF SINE: sin A / a = sin B / b = sin C / c
So in this case: sin 31 / ST = sin 58 / 28
28 sin 31 / sin 58 = ST = 17.0
sin 58 / 28 = sin 91 / x
28 sin 91 / sin 58 = RT = 33.0
It is said that happy and healthy workers are efficient and productive. A company that manufactures exercising machines wanted to know the percentage of large companies that provide on-site health club facilities. A sample of 240 such companies showed that 99 of them provide such facilities on site.
Construct a 98% confidence interval for the percentage of all such companies that provide such facilities on site. What is the margin of error for this estimate?
Answer:
Confidence interval is 0.7 ≤ p ≤ 0.8
The margin of error is 7.1 %
Step-by-step explanation:
We have to calculate a 98% confidence interval for the proportion.
The sample proportion is p=0.75.
The standard error of the proportion is:
Here we have, the proportion or point estimate given by
= 150/200 = 0.75
Sample size, n = 200
The formula for confidence interval, CI, given a proportion, is;
At 98% z = ±2.326348
Plugging in the values of, , z and n we get;
CI = 0.6787704 ≤ p ≤ 0.8212296
To one decimal place, we have
CI = 0.7 ≤ p ≤ 0.8

A square has a side length of 6. A rectangle has a length of 5x + 12 in a width of 5x. Find the sum of the areas of square and rectangle. Expand this polynomial and then factor the trinomial form.
A. (5x+12)(5x)
B.(25x+90)(x - 6/5)
C.(5x+12)(5x)+36
D.(5x+6)(5x+6)
Answer:
D) (5x + 6)(5x + 6)
Step-by-step explanation:
area of square = 6 x 6 = 36
area of rectangle = 5x(5x + 12) = 25x² + 60x
total together = 25x² + 60x + 36
factored:
(5x + 6)(5x + 6)

0 is the multiplicative inverse of 0?
Answer:
false
Step-by-step explanation:
I say false because the multiplicative inverse of 0 is undefined and the multiplicative inverse tells us that when you multiply a number by its inverse the product will be1 think the multiplicative inverse of 0 is undefined.
