of 14 cm and a diagonal
length of 50 cm. Find the
length of this rectangle in
centimeters.
Answer:
700
Step-by-step explanation:
The following P-Q data points (shown in Table 1) are obtained from the manufacturer's
static pressure curve for a single fan unit at 750 rpm and a density of 1.2 kg/m3. The speed is
to be increased to 850 rpm, the density changes to 1.16 kg/m3 and two fans are to be
operated in parallel.

because making my answer as brainlist you would not lose anything।।।।।।।।।।five people were asked about the time in a week they spend in doing social work in their community they said 7,10,13,20,15 hours respectively.
which methametical concept is used in this question??
what value is depicted in this question??
Answer:
Mean time and 13
Step-by-step explanation:
Given that
here is a five people and they spend the work in 7,10,13,20,15 hours respectively
Therefore here the concept i.e. used is average time or the meantime
And, this can be determined below:
= Sum of observations ÷ number of observations
= (7 + 10 + 13 + 20 + 15) ÷ 5
= 13

Then, briefly explain what the whole number 2, the denominator 3, and the numerator 1 mean in this problem. Part B The expression 1 ÷ 1 4 is given. Give a real-life application to explain this expression and then simplify it. plz help
There are 2 1/3 apples for each person.
The whole number 2 is the number of whole apples each person gets. The numerator 1 is the number of pieces of the remaining apple each person gets; the denominator 3 is the number of pieces the remaining apple is cut into.'
You and three friends buy a pizza with 8 slices to share. Each friend gets 2 slices each because 1 divided by 1/4 is 25% and 25% of that pizza is 2 slices

Jaclyn plays a game of chance. Each play is independent. Each time that she plays, the probability that she wins is .3. She plays 16 times. What is the probability that she will win exactly 2 times
Answer:
8
Step-by-step explanation:
The probability that Jaclyn wins exactly 2 times is 0.073
What is binomial probability?Binomial probability is the probability of exactly x successes on n repeated trials in an experiment with two possible outcomes. If the probability of success on an individual trial is p, then the binomial probability is ⁿCₓ⋅pˣ⋅(1−p)ⁿ⁻ˣ. Here ⁿCₓ indicates the number of different combinations of x objects selected from a set of n objects.
Given here:
She plays 16 times and the probability of her winning is 0.3
Thus applying the formula we get
= ¹⁶C₂× 0.3²× 0.7¹⁴
= 120×0.09×0.7¹⁴
=0.073
Hence, The probability that Jaclyn wins exactly 2 times is 0.073

Answer:
16 and 18
Step-by-step explanation:
1=5 80/5=16
1=9 2x9=18
Answer:
16 centimeters and 18 feet
Step-by-step explanation:
The scale for the fist one is 1 centimeter and that gives you 5 meters. So set up a proportion to see what 80 meters would get you. 1cm/5m=Xcm/80m. You would divide 80 by 5 to find the amount of centimeters which would be 16.
For the next one it is similar. Set up the proportion 1in/9ft=2in/Xft. You would end up with x=9times2 which would give you 18 ft.
how do you do this??

Sorry to disappoint, but none of these answers are correct. All three limits are equal to 7.
Compute the one-sided limits:
[tex]\displaystyle\lim_{x\to2^-}h(x)=\lim_{x\to2}(x^2-x+5)=2^2-2+5=7[/tex]
[tex]\displaystyle\lim_{x\to2^+}h(x)=\lim_{x\to2}(x^3-1)=2^3-1=7[/tex]
Both the one-sided limits agree, so the two-sided limit has the same value,
[tex]\displaystyle\lim_{x\to2}h(x)=7[/tex]

Seven students volunteered for a comparison of study guides for an advanced course in mathematics. They were randomly assigned, four to study guide A and three to study guide B. All were instructed to study independently. Following a two-day study period, all students were given an examination about the material covered by the guides, with the following results:Study Guide A scores: 68; 77; 82; 85Study Guide B scores: 53; 64; 71Perform a randomization test by listing all possible ways that these students could have been randomized to two groups. There are 35 ways. For each outcome, calculate the difference between sample averages. Finally, calculate the two-sided p-value for the observed outcome
Answer:
Step-by-step explanation:
From the given question; we can use the R software to program the combination function that generates all the combinations.
options(digits =2(
scores<- c(68,77,82,85,53,64,71)
groupA <- combn(scores,4)
groupB <- apply(groupA,2, function(x) scores[! (scores %in% x) ] )
colnames(groupA) <- colnames(groupB) <- paste("G", 1:35, sep"")
