=x3*x5
=(x*x*x)*(x*x*x*x*x)
=x*x*x*x*x*x*x*x
=x8

Step-by-step explanation:
[tex]x^{3} = x*x*x\\x^{5} = x*x*x*x*x\\x^{3} x^{5} = x*x*x*x*x*x*x*x = x^{8}[/tex] ≠ [tex]x^{15}[/tex]

The scores on a test are normally distributed with a mean of 130 and a standard deviation of 26. What is the score that is 25 standard deviations below the mean?
Answers
Answer: The z-score for an ACT score of 26 is 0.17.
Step-by-step explanation:
Z-score:
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In a particular year, the mean score on the ACT test was 25 and the standard deviation was 5.9.
This means that
Find the z-score for an ACT score of 26.
This is Z when X = 26. So
The z-score for an ACT score of 26 is 0.17.
The z-score for an ACT score of 26 is 0.17.
What is z-score?
When assessed in terms of standard deviation units, a raw score's location in relation to its distance from the mean is indicated by a z-score. If a value is above the mean, the z-score is positive; if it is below the mean, it is negative.
In a set with mean and standard deviation , the z-score of a measure X is given by: z-score=(x-μ)/σ
How do you find z-score?
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In a particular year, the mean score on the ACT test was 25 and the standard deviation was 5.9.
This means that
We need to find z-score for an ACT score of 26.
This is Z when X = 26. So
The z-score for an ACT score of 26 is 0.17

This recipe makes 6 portions of fajitas.
Carly has 900 g of chicken, 1200 g of peppers, 150 g of onion, 60 g of spice mix and 30 tortillas.
How much more of each ingredient will she need to make 18 portions by following this recipe?
Recipe: Serves 6
500 g chicken
600 g peppers
90 g onion
25 g spice mix
12 tortillas
Answers
Answer:
She needs:
600 g chicken
600 g peppers
120 g onion
15 g spice mix
6 tortillas
Step-by-step explanation:
hope this helps and is right. p.s. i really need brainliest :)
Well, first we multiply every ingredient in the recipe amount by 3, because 6 x 3 = 18. Then we’ll subtract what we have from what we need.
500 x 3 = 1500g of chicken
600 x 3 = 1800g of peppers
90 x 3 = 270g of onion
25 x 3 = 75g of spice mix
12 x 3 = 36 tortillas
Chicken: needs 1500, has 900
1500 - 900 = 600g more chicken needed
Peppers: needs 1800, has 1200
1800 - 1200 = 600g more peppers needed
Onion: needs 270, has 150
270 - 150 = 80 g more onion needed
Spice mix: needs 75, has 60
75 - 60 = 15g more spice mix needed
Tortillas: needs 36, has 30
36 - 30 = 6 more tortillas needed

What are the next two terms in the sequence 1, 8, 27, 64..., written as coordinate pairs (n,
an)?
A) (5, 75), (6,86)
B) (5, 81), (6,100)
C)(5, 125), (6, 216)
D) (125, 5), (216, 6)
Answers
Answer:
C)(5, 125), (6, 216)
Step-by-step explanation:
Well firstly, there's no actual way to know. There could be anything there, as for any n pairs (x, y) with distinct x-s, there exists a (n-1 or less)-degree polynomial that models them perfectly, and infinitely many polynomials of degree n (or more).
If we input those terms to a polynomial interpolator, we'll get an answer every time.
With this one, it will be the right answer though!
But to be serious, let's find out what the numbers are. We can notice they're all cubic numbers.
There's 1, which is 1^3, then theres 2^3, then it's 3^3, then 4^3.
It's reasonable to expect that we are expected to assume (x, x^3) is the rule.
We can see that the answer C (5, 5^3), (6, 6^3) fits this narrative.

MATH QUESTION PLEASE HELPPP ASAP, DUE IN AN HOUR
Answers
Answer:
Perimeter = [tex](30-\frac{3}{2}x)[/tex]
Step-by-step explanation:
Width of the rectangle has been given as [tex](5-\frac{1}{4}x)[/tex].
Convert the statement into the algebraic expression,
"Length of the rectangle is twice the width"
Length = 2(Width)
= [tex]2(5-\frac{1}{4}x)[/tex]
= [tex]10-\frac{1}{2}x[/tex]
Since perimeter of a rectangle is given by the expression,
Perimeter = 2(Length + Width)
By substituting the values of length and width in the expression,
Perimeter = [tex]2[(5-\frac{1}{4}x)+(10-\frac{1}{2}x)][/tex]
= [tex]2(15-\frac{3}{4}x)[/tex]
= [tex](30-\frac{3}{2}x)[/tex]
Therefore, expression representing perimeter is [tex](30-\frac{3}{2}x)[/tex].

$99. 100%
$X. 130%
X=99•130/100
X=12870/100
X=128.70$
4 b) If X is increased price
99•(130:100)=X
99•1.3=X
Equality:
99•(130:100)=99•1.3
99•1.3=99•1.3

a) AB=8X
Reduction of 40%
40%=4/10=2/5
AB’ =8X•2/5
AB’=16X/5
b) AC=6X
AC’ =6X•2/5
AC’=12X/5
c) CB? Can’t see the vector
CB= 2X+10
CB’ = 2X+10•2/5
CB’ = 2(2X+10)/5
CB’ = 4X+20/5
d) P of reduced triangle
P’ = AB’ + AC’ + CB’
P’ = 16X/5+12X/5+4X+20/5 all sides have same denominator of 5 therefore we can add them up,
P’ = 16X+12X+4X+20 all over 5
P’ = 32X+20/5=4(8X+5)/5
Good luck.
