76 minutes for 38 songs = ? minutes for 21 songs
Answer:
42 minutes for 21 songs
Step-by-step explanation:
My way to go about solving these is weird, so sorry in advance
76 minutes / 38 songs = 2 minutes per song,
so for 21 songs its 21x2 or 42
42 minutes for 21 songs

Hi Is 4/8 equal 8/10
<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer:
No
0.5 ≠ 0.8
<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer:
No, it is not.
Step-by-step explanation:
The reason is that if you simplified 4/8, you will get 1/2. When you simplified 8/10, you will get 4/5. 1/2 and 4/5 aren't the same number or equivalent to each other so the answer will be no.

Lana finished the race in 13.2 seconds . If 84 other girls ran in the event, approximately how many runners did she beat?
Complete question :
The 100m dah times in the girl's track meet were normally distributed with a mean of 13 seconds and a standard deviation of 0.3 seconds.
Lana finished the race in 13.2 seconds . If 84 other girls ran in the event, approximately how many runners did she beat?
Answer:
21 runners
Step-by-step explanation:
Mean, μ = 13 seconds
Standard deviation, σ = 0.3
Lana's race time = 13.2
We find the proportion of runners who had race time above 13.2 ;
Proportion of who had race tune above 13.2
P(x > 13.2)
Obtain the Zscore
Zscore = (x - μ) / σ
Z = (13.2 - 13) / 0.3
Zscore = 0.2 / 0.3 = 0.6667
P(Z > 0.6667) = 0.25239 (Z probability calculator)
This is about 0.25239 * 100 = 25.24% = 25% (nearest percent)
Hence, Number of runners Lana beat = 25% of total runners ;
0.25 * 84 = 21
Hence, Lana beat about 21 runners

Answer:
Question 1: x = 3, y = 2
Question 2: x = 0.5
Step-by-step explanation:
Question 1 explanation: In a parallelogram, both the horizontal and the vertical sides are equal, this means that [tex]2y + 3 = y + 5[/tex] ⇒ [tex]y = 2[/tex]. Since you've already figured out the value of y, you can input the value to side QR to help find x. [tex]4x-3=4*2+1[/tex] ⇒ [tex]4x-3=9[/tex] ⇒ [tex]4x=12[/tex] ⇒ [tex]x=3[/tex]. So x equals 3 and y equals 2.
Question 2 explanation: Since side AE is equivalent to side EC, that means quadrilateral ABCD is a parallelogram. In a parallelogram, the diagonal lengths from the corners of the shape to the center are equal, which means [tex]10x = 2x + 4[/tex] ⇒ [tex]8x=4[/tex] ⇒ [tex]x = 0.5[/tex].
If y equals -3 then 4 + y / 4 y =
Answer:
[tex] y = - 3 \\ \frac{4 + y}{4y} = \frac{4 + ( - 3)}{4( - 3)} = \frac{4 - 3}{ - 12} = \frac{ - 1}{12} [/tex]

For a certain population of sea urchins, 16% are longer than 8 inches. A random sample of 75 sea urchins will be selected. What is the standard deviation of the sampling distribution of the sample proportion of sea urchins longer than 8 inches for samples of size 75?
Answer:
0.042
Step-by-step explanation:
Given :
p = 16% = 0.16
q = 1 - p = 1 - 0.16 = 0.84
Sample size, n = 75
The standard deviation of sampling distribution :
√(pq)/n
√(0.16 * 0.84) / 75
√0.1344 / 75
√0.001792
Standard deviation of sampling distribution = 0.0423320

I don't understand. but I think the screenshot will be useful
Answer:
a) 7, 10, 13, 16, ..., 34
Step-by-step explanation:
I'll only solve part a and you'll be able to do part b.
You're given:
3n+4
to find the first four terms, just plug in n = 1, 2, 3, 4 into n.
for n=1: 3(1)+4 = 7
for n=2: 3(2)+4 = 10
for n=3: 3(3)+4 = 13
for n=4: 3(4)+4 = 16
as you might guess, to find the 10th term, you plug in n=10.
for n=10: 3(10)+4 = 34

Find the maximum value of
P = 4x + 5y
subject to the following constraints:
x + 3y = 13
3x + 2y < 25
X>0
y>0
P = [?]
Answer:
38 is the maximum value
Step-by-step explanation:
First we should graph each inequality. Then we can find the points on the intersecting region and take those points and plug them into the equation P = 4x + 5y. Then we can find the maximum value from there. The maximum value is tied to the point (7, 2), with P = 38. :)

2.
What is the median?
3.
What is the range?
4.
What is the mean absolute deviation?
Answer:
The mean is 70, that's all I know. Sorry!
Step-by-step explanation:
Here's how you find the mean:
1. Add together ALL NUMBERS. (which equals 560 in this case.)
2. DIVIDE by the amount of numbers there are. (So 560 ÷ 8 = 70)
3. There's your answer! The mean of these numbers is 70.

John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer. John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit. Caleb decided to go to Club4Fitness, which just charges $8 per visit. After how many visits have John and Caleb spent the same amount of money, and how much money did they spend?
Answer:
10 visits
Step-by-step explanation:
John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer.
Let the number of visits be represented as: x
For John
John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit.
The equation = $30 + $5 × x
= 30 + 5x
For Caleb
Caleb decided to go to Club4Fitness, which just charges $8 per visit.
The Equation = $8 × x
= 8x
We equate both equations to each other
30 + 5x = 8x
Collect like terms
30 = 8x - 5x
30 = 3x
x = 30/3
x = 10
Therefore, John and Caleb would spent the same amount of money after 10 visits.

Martin has a combination of 33 quarters and dimes worth a total of $6. Which system of linear equations can be used to find the number of quarters, q, and the number of dimes, d, Martin has?
q + d = 6 25q + 10d = 33
q + d = 6 0.25q + 0.1d = 33
q + d = 33 25q + 10d = 6
q + d = 33 0.25q + 0.1d = 6
Answer:
q + d = 33 0.25q + 0.1d = 6 Option D
Step-by-step explanation:
The system of linear equation that can be used to find the number of quarters, q, and the number of dimes, d, Martin has is as follows:
q + d = 33
0.25q + 0.1d = 6
Martin has a combination of 33 quarters and dimes worth a total of $6.
Therefore,
q = number of quarters
d = number of dimes
The linear equation can be represented below:0.1 dollars = 1 dime
0.25 dollars = 1 quarters
Therefore,
0.25q + 0.1d = 6
The quarters and dimes total 33. Therefore,
q + d = 33Therefore, the combined equation will be as follows:
q + d = 33
0.25q + 0.1d = 6
