Answer:
10
Step-by-step explanation:
80%=8markers which were black
so 100%will be equal to what
so equate 80%=8
100%=?

=10 am not sure but I think it's like that
What is this expression in simplified form?
3✓3 • 6✓6 (Square root)
Answer:
54√2
Step-by-step explanation:
3√3 . 6√6 = (3 . 6)√(3 . 6)
= 18√18
= 18√9 . √2
= 18 . 3√2 = 54√2.
The length of a rectangle is three more than its width. If the perimeter is 46 feet, what are the dimensions of the rectangle?
O 10 by 7
0 43 by 3
O 12 by 11
O 13 by 10
Answer:
13 BY 10
Step-by-step explanation:
let width be z
length be z+3
perimeter=46
2(l+b)=46
z+z+3=23
2z=20
z=10
z+3=l=13
If probability is greater than the level of significance then,
we should accept or reject null hypothesis?
Answer:
One of the most basic concepts in statistics is hypothesis testing. Not just in Data Science, Hypothesis testing is important in every field. Want to know how??? Let us take an example. You must have heard about lifebuoy?? Suppose
lifebuoy claims that, it kills 99.9% of germs. So how can they say so? There has to be a testing technique to prove this claim right?? So hypothesis testing uses to prove a claim or any assumptions.
Hopefully, this helps! :D

Tres compañías aportan capitales para hacer una investigación la estrella aporta 509000 724 flechabús la mitad de lo que aporta la estrella más 23184 y la terminal 104208 menos que lo que aporta flechabús cuánto aportan en total cada uno de los tres juntos
Answer:
En total, se invirtieron $960,000 por parte de las tres empresas.
Step-by-step explanation:
Para resolver cuánto dinero aportaron en total las tres empresas, es necesario determinar la cantidad de dinero que cada una de ellas aportó en forma particular. Así:
La Estrella: 509,000
Flechabus: (509,000 / 2) + 23,184
254,500 + 23,184
277,684
La Terminal: ((509,000 / 2) + 23,184) - 104,208
277,684 - 104,208
173,476
Ahora bien, para determinar el total invertido se requiere sumar dichos montos: 509,000 + 277,684 + 173,476 = 960,160
Así, en total, se invirtieron $960,000 por parte de las tres empresas.

Find the probability that an individual distance is greater than 218.00 cm. b. Find the probability that the mean for 15 randomly selected distances is greater than 204.00 c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
Answer:
a) 0.073044
b) 0.75033
c) The normal distribution can be used in part (b), even though the sample size does not exceed 30 because initial population size is been distributed normally , therefore, the mean of the samples will be normally distributed regardless of their size(meaning whether the sample size is less than or equal to or exceeds 30, the sample means the mean of the samples will be normally distributed regardless of their size).
Step-by-step explanation:
The overhead reach distances of adult females are normally distributed with a mean of 205.5 and a standard deviation of 8.6 .
a. Find the probability that an individual distance is greater than 218.00 cm.
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 218
μ is the population mean = 205.5
σ is the population standard deviation = 8.6
For x > 218
z = 218 - 205.5/8.6
z = 1.45349
Probability value from Z-Table:
P(x<218) = 0.92696
P(x>218) = 1 - P(x<218) = 0.073044
b. Find the probability that the mean for 15 randomly selected distances is greater than 204.00
When = random number of samples is given, we solve using this z score formula
z = (x-μ)/σ/√n
where
x is the raw score = 204
μ is the population mean = 205.5
σ is the population standard deviation = 8.6
n = 15
For x > 204
Hence
z = 204 - 205.5/8.6/√15
z = -0.67552
Probability value from Z-Table:
P(x<204) = 0.24967
P(x>204) = 1 - P(x<204) = 0.75033
c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
The normal distribution can be used in part (b), even though the sample size does not exceed 30 because initial population size is been distributed normally , therefore, the mean of the samples will be normally distributed regardless of their size(meaning whether the sample size is less than or equal to or exceeds 30, the sample means the mean of the samples will be normally distributed regardless of their size).
The equation below describes a linear function. y=−2(x+1)+4 The range of the function is {−4,−2,4} . What is the domain of the function
9514 1404 393
Answer:
{-1, 2, 3}
Step-by-step explanation:
We need to find the values of x that correspond to these y-values.
{-4, -2, 4} = -2(x +1) +4 . . . substitute the range values for y
{2, 1, -2} = x +1 -2 . . . . . . .divide by -2
{2, 1, -2} = x -1 . . . . . . . . . simplify
{3, 2, -1} = x . . . . . . . . . . . add 1
The domain of the function is {-1, 2, 3}.

answer correctly pleasee
Answer:
Slope= 4
Step-by-step explanation:
When you start at (0, 0) and then go to (1, 4), then you have to use the slope.
So, to figure out the slope, you have to do rise over run, rise/run.
So, as shown in the graph, the rise is 4 because the rise is the y so to get from 0 to 4, you have to add 4.
And the run, which would be the x side is 1 because to get from 0 to 1. You add 1.
This shows us that the slope is 4/1 which could be simplified to just 4.

How do you write intervals of increase and decrease?
Answer:
add one per interval
Step-by-step explanation:
an example would be:
+1
+2
+3
or:
+4
+8
+12
Answer:
As part of exploring how functions change, we can identify intervals over which the function is changing in specific ways. We say that a function is increasing on an interval if the function values increase as the input values increase within that interval. Similarly, a function is decreasing on an interval if the function values decrease as the input values increase over that interval. The average rate of change of an increasing function is positive, and the average rate of change of a decreasing function is negative.
The image below shows examples of increasing and decreasing intervals on a function.
What is the definition of "constant of proportionality"? Define or show an expression to prove your answer
Answer:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate.

Answer:
I don't know how to answer question 1, but the answer from question 2 is x=5
Step-by-step explanation:
The triangle shown is an isosceles triangle because it has two congruent sides. The base angles of isosceles triangles are congruent so ∠y=∠x. since the ∠x is 52 the ∠y is also 52. We subtract the measure of angles x and y in order to find the measure of the third angle. 180-(52+52) or 180-104 is 76. this means that 14x=6=76. All we have to do to get the answer now is solve. 76-6 is 70 and 70 divided by 14 is 5. x=5.
Find value of x. I will report if u put gibberish
Answer:
