it droped 40 degres
Step-by-step explanation:
Answer:
The temperature dropped 4 degrees per 1000 feet.
Step-by-step explanation:
90 - 50)/(10,000:1,000) = 40/10 = 4 degrees per 1000 ft
Two dice are rolled. What is the probability that the sum of the numbers rolled is either 4 or 9? Express your answer as a fraction in lowest terms or a decimal rounded to
the nearest millionth.
Answer:
1/4
Step-by-step explanation:
There are 36 possible combinations. Of those 36, the ones that add up to either 6 or 9 are:
1+5, 2+4, 3+3, 4+2, 5+1, 3+6, 4+5, 5+4, 6+3
There are 9 combinations that add up to either 6 or 9. So the probability is 9/36, or 1/4.

Find the value of x, y and z. Round to the
nearest whole number.
Hello!
We can say that:
x = 35y = 18z = 13Let's go!Calculate x, knowing that angles opposite the vertex have the same value: ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
4x - 21 = 2x + 74x - 2x = 7 + 212x = 28x = [tex]\dfrac{28}{2}[/tex] x = 14To know the value of y, just calculate when the angle 4x - 21 ° is worth, as we already have the value of x. Then just do another equation.
4.14 - 2156 - 21 35Now, we calculate:
6y + 37 + 35 = 1806y + 72 = 1806y = 180 - 726y = 108y = [tex]\dfrac{108}{6}[/tex] y = 18Now, we calculate z:
180 - 35 → (35 is the value of 4x - 21 angle, and the adjacent angle of 2x + 7 is same to 10z + 15)= 145Now, we calculate:10z + 15 = 14510z = 145 - 1510z = 130z = [tex]\dfrac{130}{10}[/tex] z = 13Is important stand out what the draw isn't in the correct scale.
Hope this helps!!!! Good studies! ☺

Which line is parallel to the line 8x + 2y = 12?
Help ASP please!!!
To be parallel must the slope of the lines equal to each other.
_________________________________
[tex]8x + 2y = 12[/tex]
[tex]2y = - 8x + 12[/tex]
[tex]y = - 4x + 6[/tex]
_________________________________
From left to right ;
1) The slope-intercept form is :
[tex]y = 4x + 4[/tex]
Which means the slope = 4
Look : 4 ≠ -4 thus this is not the answer.
+++++++++++++++++++++++++++++++++++++++
2) The slope-intercept form is :
[tex]y = - \frac{1}{4}x + \frac{3}{4} \\ [/tex]
Which means the slope = -¼
Look : -¼ ≠ -4 thus this is not the answer.
+++++++++++++++++++++++++++++++++++++++
3) The slope-intercept form is :
[tex]y = - 4x - 6[/tex]
Which means the slope = -4
Look : -4 = -4 thus this is the answer.
+++++++++++++++++++++++++++++++++++++++
4) The slope-intercept form is :
[tex]y = \frac{1}{4}x + \frac{11}{4}\\ [/tex]
Which means slope = ¼
Look : ¼ ≠ -4 thus this is not the answer.

Write an equation (any form) for the quadratic graphed below
Answer:
[tex]-\frac{1}{2} (x - 1)^2 + 1[/tex]
Explanation:
Since it is flipped and now extending to negative infinity, we make [tex]x^2[/tex] negative, so it is [tex]-x^2[/tex].
Lastly, there are a few shifts, it is shifted right once and up once.
To shift it right once, you would subtract a 1 from x directly: [tex]-(x - 1)^2[/tex]
To shift it up once, you would add 1 to the entire equation: [tex]-(x - 1)^2 + 1[/tex]
To account for the stretching, it would be: [tex]-\frac{1}{2} (x - 1)^2 + 1[/tex]

A set of 200 scores is normally distributed with a mean of 60 and . a standard deviation of 12. a, What are the z-scores corresponding to the. raw scores .of 76, 38; and 50
Answer:
Z scores for:
a) 76 = 1.33333
b) 38 = -1.83333
c) 50 = -0.83333
Step-by-step explanation:
Z score formula is:
z = (x-μ)/σ where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Mean = 60
Standard deviation = 12.
a) 76
z = (x-μ)/σ
z = 76 - 60/12
z score = 1.33333
b) 38
z = (x-μ)/σ
z = 38 - 60/12
z score = -1.83333
c) 50
z = (x-μ)/σ
z = 50 - 60/12
z score = -0.83333

Please ASAP What is the remainder when x3−2x2−51x−108 is divided by x−2?
Answer:
[tex]-210[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=x^3-2x^2-51x-108[/tex]
And we want to find the remainder when it is divided by [tex](x-2)[/tex].
We can use the Polynomial Remainder Theorem, where if we have a function [tex]f(x)[/tex] divided by a binomial [tex](x-a)[/tex], then our remainder will be [tex]f(a)[/tex].
Here, our divisor is [tex](x-2)[/tex], so our a is 2.
Therefore, our remainder will be [tex]f(2)[/tex]. Let's substitute this for x. This yields:
[tex]f(2)=(2)^3-2(2)^2-51(2)-108[/tex]
Evaluate. Do the exponents:
[tex]f(2)=8-2(4)-51(2)-108[/tex]
Multiply:
[tex]f(2)=8-8-102-108[/tex]
Subtract:
[tex]f(2)=-210[/tex]
So, our remainder is -210.
And we're done!
The coordinates of point T are (0, 5) . The midpoint of overline ST is (1, - 2) . Find the coordinates of point S
Plz hurry if u can!!!
The midpoint of a line segment is the point equidistant to the endpoints of the line. The coordinate of S is (2,-9)
Given that:
[tex]T(x_1,y_1) = (0,5)[/tex]
[tex]M = (1,-2)[/tex] --- the midpoint of ST
[tex]S = (x_2,y_2)[/tex]
To calculate the coordinates of S, we use the following midpoint formula:
[tex]M = 0.5 \times (x_1 + x_2,y_1+y_2)[/tex]
So, we have:
[tex](1,-2) = 0.5 \times (0 +x_2,5 + y_2)[/tex]
Divide both sides by 0.5
[tex](2,-4) = (0 +x_2,5 + y_2)[/tex]
[tex](2,-4) = (x_2,5 + y_2)[/tex]
Compare both sides
[tex]x_2 = 2[/tex]
[tex]5 + y_2 = -4[/tex]
Collect like terms
[tex]y_2 = -4-5[/tex]
[tex]y_2 = -9[/tex]
Hence, the coordinates of S is:
[tex]S = (2,-9)[/tex]
