On one day in January, the temperature in Milwaukee, Wisconsin fell 12°F from the high temperature to a low temperature of -8°F. If t represents the high temperature, what is the value of t?
Answer:
t = 4
Step-by-step explanation:
you have -8 and twelve you equation is x -12 = -8 so we just have to flip the equation around to make it x = 12 -8 which is easy . You just have to make sure you don't get mixed up while flipping the signs.
The value of t is 4.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
The temperature in January = 12 °F
And the low temperature is = -8 °F
The equation of temperature t can be given as

A simple random sample of 25 items from a normally distributed population resulted in a sample mean of 28 and a standard deviation of 7.5. Construct a 95% confidence interval for the population mean.
Answer:
CI = 28 ± 3.09
Step-by-step explanation:
The sample size, n = 25
The sample mean, m = 28
Standard deviation, s = 7.5
Confidence interval is given as:
CI = Sample mean ± margin of error
We want to find 95% confidence level:
First, let us find the margin of error:
Margin of error = Critical value * standard error
To find the critical value, we need some parameters:
Standard error = [tex]s / \sqrt{n}[/tex]
=> [tex]SE = 7.5 / \sqrt{25}= 7.5 = 5 = 1.5[/tex]
The alpha value, ∝ = 1 - (confidence level / 100) = 1 - 95/100 = 1 - 0.95 = 0.05
Critical probability, p, is given as:
p = 1 - ∝/2 = 1 - 0.05/2 = 1 - 0.025 = 0.975
Now we need the degree of freedom:
df = n - 1 = 25 - 1 = 24
Therefore, the critical value is 2.06 (you can use an online t value calculator).
=> Margin of error = 2.06 * 1.5 = 3.09
Therefore, the confidence interval for the population mean is:
CI = 28 ± 3.09

Can someone PLEASE explain in simple terms which trigonometric ratio to use, like tangent, cosine, or sine, and WHY?
Answer:
Use law of Cosines or Tangent
Step-by-step explanation:
This is a SAS triangle, where you have have an angle adjacent to two side lengths. But given that it is a right triangle, you can find the hypotenuse by just using the tangent formula. You can find the quantity of any angle by applying tan= opposite side/adjacent side length.
However, lets say you want to find the opposite side, side XZ, you can use the law of cosine which basically states:
c=a^2+b^2﹣2abcos(angle number). But since it is a right triangle, just use the hypotenuse theorem which states: C^2 = A^2 + B^2
The answer for XZ would thus be: squareroot of 136 or 2(34)^1/2.

Answer:
Cheapest price is £25.38
Step-by-step explanation:
To determine the cheapest price that Sue can get the 10 rolls of wallpaper, calculate the cost of getting 10 rolls at each given price offer
=>Cost of getting 10 rolls at £9.21 per roll:
10 × £9.21 = £92.1
=>Cost of getting 10 rolls at £25.38 per pack of 3 rolls
£25.38 = 3 rolls
x = 10 rolls
x = (25.38*10)/3 = 253.8/3
10 rolls would cost x = £84.6
=>Cost of getting 10 rolls at £42.85 per pack of 5 rolls:
£42.85 = 5 rolls
x = 10 rolls
x = (10*42.85)/5 = 428.5/5
x = £85.7
From our calculation, getting 10 rolls at the price offer of £25.38 per pack of 3 rolls is the cheapest.
Therefore, the cheapest price is £25.38

Answer: (originally answered by DeanR so credit to him)
x=6
Step-by-step explanation:
x3579x = 100000 x + 35790 + x
100000 = 2380 × 42 + 40
35790 = 852×42 + 6
Working mod 42,
100000 x + 35790 + x = 40 x + 6 + x = 41x + 6 = 6-x (mod 42)
So basically we need 6-x to be a multiple of 42, so between 0 and 9 that's x=6.
So our number is
635796 = 15138 × 42
Answer:
x=6
Step-by-step explanation:
All of the factors of 42 under are only 7 and 6. Substitute one of them for x. 7 is wrong so 6 is the answer.
A cone with radius 2 units is shown below. Its volume is 29 cubic units.
h
Find the height of the cone.
Use 3.14 form and round your ina answer to the nearest hundredth.
Answer:
[tex]h=6.93units[/tex]
Step-by-step explanation:
1. Use the formula of volume of a cone
Volume of a cone=[tex]\frac{1}{3}\pi r^{2} h[/tex]
2. Collecting the information from a question.
In the question, we know that radius=2 units, Volume of a cone=29 cubic units, height of a cone=?
In this question, we can also know that the question requires us to find the height of a cone.
3. Put the value of variables into the formula.
We can put all the information that are provided by a question into the formula of volume of a cone to find the answer.
[tex]\frac{1}{3} *3.14 * 2^{2} h=29 units^{3}[/tex]
pi replaces with 3.14, radius replaces with 2 units, Volume of a cone replaces with 29 units3 and we don't know what is the value of h.
Now, let's simplify and calculate the value of h.
We can simplify the formula like this,
[tex]\frac{314}{75}h =29 units^{3}[/tex]
[tex]\frac{314}{75}[/tex] is the result of [tex]\frac{1}{3}* 3.14*2^{2}[/tex]
Move [tex]\frac{314}{75}[/tex] to other side.
[tex]h=\frac{29units^{3} }{\frac{314}{75} }[/tex]
[tex]h= 6.92675 units[/tex]
But wait, this is not final answer yet, the question requires the answer to the nearest hundredth. So, we need to convert the answer to the nearest hundredth.
[tex]h= 6.92675 units[/tex]
[tex]h=6.93units[/tex]
So, the final answer is 6.93 units.

Graph the relation shown in the table. Is the relation a function? Why or why not? {(-1, 9), (0, -1), (-1, 4), (4, 9)}
Answer:
Not a function
Step-by-step explanation:
For an equation to be a function, there should be only one y-coordinate per x-coordinate. Since this relation has both (-1,9) and (-1,4), this is not a function.
Answer:not a function
Step-by-step explanation:
because when you put the points on the coordinate plane your shape will come out as a v shaped object. In mathematics, a function is a binary relation over two sets that associates to every element of the first set exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers

Estimate the number of white cars you would expect to see if 4000 cars passed by?
Answer:
444
Step-by-step explanation:
13 + 34 + 25 + 10 + 8 = 90
10/90 * 4000 = 444
Answer: You will expect 444 white cars passed by.
Step-by-step explanation:
The are 5 different colors so we need to find the probability of white cars.
There are 10 white cars But we need to find the total number of cars in all.
13+34+25+10+8 = 90
so the probability of a white car passing by is 25/90 = which reduces to 10/90
Now multiply 1/9 by 4000.
1/9 * 4000 = 444
