Answer:
1.2 x 10^-1
Step-by-step explanation:
So you are going to move the decimal to the right once, since it is where the first number is. Since you only moved the decimal once it is 10^-1. It is negative because you moved the the right. If you had moved the decimal to the left it would be positive.

g Keith sampled 10 private universities in Colorado and recorded the tuition cost. Keith wants to test the hypothesis that the tuition of these 10 universities is more expensive than the national average tuition, which is $29,056 with a population standard deviation of $3,339. z equals fraction numerator x with bar on top minus mu over denominator begin display style fraction numerator sigma over denominator square root of n end fraction end style end fraction If the sample mean is $31,650, what is the z-score
Answer:
69
Step-by-step explanation:
Answer:
Z score=2.46.
Step-by-step explanation:
The Z score for sample mean $31,650 can be computed by using following formula
[tex]Z=\frac{xbar-Population mean}{\frac{sigma}{\sqrt{n} } }[/tex]
Here, sample mean=xbar=31650
population standard deviation=sigma=3339
population mean=29056
and sample size=n=10.
[tex]Z=\frac{31650-29056}{\frac{3339}{\sqrt{10} } }[/tex]
[tex]Z=\frac{2594}{1055.885}[/tex]
Z=2.4567
Z=2.46 (rounded to two decimal places).
Hence the resultant z-score is 2.46.

Answer:
y = 4/3
Step-by-step explanation:
the expression can be written as,
(x^8)^1/3 divided by (x^4)^ 1/3
so by using the rules of powers we can deduce y = 4/3
The rules are,
1. (x^y)^z = X^y*z
2. x^y * x^z = x^ y+z
3. x^y / x^z = x^ y-z
Hence,
8/3 -4/3 = 4/3

help!! BRAINLIEST!The outside temperature at midnight today in Polina’s hometown was 18 degrees Fahrenheit. The temperature increases by 1.2 degrees Fahrenheit each hour over the next 15 hours. Polina’s school does not send students outside for recess if the outside temperature is 32 degrees Fahrenheit or lower. Recess at her school always starts on the half hour or hour. Which statement is true about recess at Polina’s school?
Only students who have recess at 11:00 a.m. or later may go outside.
Only students who have recess at 11:30 a.m. or later may go outside.
Only students who have recess at 12:00 p.m. or later may go outside.
Only students who have recess at 12:30 p.m. or later may go outside.
Answer:
Only students who have a recess at 12:00 pm or later may go outside
Step-by-step explanation:
it is 18 degrees at midnight and the temp. increases 1.2 every hour.
so 1.2 times 12 hours equal 14.4
add 14.4 to 18 drgrees equal 32.4

In which table does y vary directly with x
Answer:
No. C
Step-by-step explanation:
please mark me brainleast
Table C shows the proportional relationship between x and y that y varies directly with x option (C) is correct.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
We have:
y vary directly with x
y ∝ x
y = kx
k is the constant.
k = y/x
Checking table A:
k = -2/1 = -4/2 ≠ -16/3
Checking table B:
k = -5/1 ≠ 18/2 = 41/3
Checking table C:
k = 26/1 = 52/2 = 78/3 = 26
Thus, table C shows the proportional relationship between x and y that y varies directly with x option (C) is correct.

In a triangle the first angle is greater than the second angle by 18 degree and less than the third angle by 10 grade. Express all the angles in grade.
Answer:
The 3 angles are 62 2/3, 44 2/.3 and 72 2/3 degrees.
Step-by-step explanation:
let x be the first angle then the the second angle is x - 18 and the third angle = x + 10
The 3 angles add up to 180 so:
x + x - 18 + x + 10 = 180
3x = 180 + 18 - 10 = 188
x = 188/3 = 62 2/3 degrees.
x - 18 = 44 2/3
x + 10 = 72 2/3.

Find the derivative of the function.
g(x)=∫5x4xu2−1u2+1 du.
Answer:
[tex]g'(x) = \dfrac{5 *(25x^2-1)}{(25x^2+1)}- \dfrac{4 * (16x^2-1)}{(16x^2+1)}[/tex]
Step-by-step explanation:
Given that:
[tex]g(x) = \int^{5x}_{4x} \dfrac{u^2-1}{u^2+1} \ \ du[/tex]
Then: the derivative of the function is as follows:
[tex]g'(x) = \dfrac{(5x)^2-1}{(5x)^2+1} \ \ \dfrac{d}{dx}(5x) -\dfrac{(4x)^2-1}{(4x)^2+1} \ \ \dfrac{d}{dx}(4x)[/tex]
[tex]g'(x) = \dfrac{5 *(25x^2-1)}{(25x^2+1)}- \dfrac{4 * (16x^2-1)}{(16x^2+1)}[/tex]

plz hellppppp (6h + 8) - (3h + 2) = 15
Answer:
h = 3
Step-by-step explanation:
Step 1: Write out equation
(6h + 8) - (3h + 2) = 15
Step 2: Distribute negative
6h + 8 - 3h - 2 = 15
Step 3: Combine like terms
3h + 6 = 15
Step 4: Subtract 6 on both sides
3h = 9
Step 5: Divide both sides by 3
h = 3
Step 6: Check Step
(6(3) + 8) - (3(3) + 2) = 15
(18 + 8) - (9 + 2) = 15
26 - 11 = 15
15 = 15
(6h + 8) - (3h + 2) = 15
Let's distribute the - to 3h + 2
6h + 8 - 3h - 2 = 15
Combine like terms
3h + 6 = 15
Subtract 6 from both sides
3h = 9
Divide both sides by 3
h = 3

1. Joanne's waitressing job gave her a raise of $2 per hour. The first day on her new
wage, she worked half of a full a workday and made $36 (not including tips).
Answer:
What exactly is the question?
On the first day on Joanne's new wage, she worked for 18 hours.
Given that, Joanne's waitressing job gave her a raise of $2 per hour.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The first day on her new wage, she worked half of a full a workday and made $36.
Number of hours she worked = Total money she made/Money paid per hour
= 36/2
= 18 hours
Therefore, on the first day on Joanne's new wage, she worked for 18 hours.
