Answer: 17°F
Step-by-step explanation:
Let the the town high temperature .In degrees Fahrenheit ,for January be represented by x
Since the town had low temperature for January was -8 Fahrenheit and the difference between the town high temperature and low temperature for January was 25. Then, the high temperature will be:
x - (-8) = 25
x + 8 = 25
x = 25 - 8
x = 17°F

Answer:
The length (which is the bottom and top lines) are both 9 inches long.
Step-by-step explanation:
To find the perimeter with only one given measurement and the total perimeter, first you need to double the given value. In this case it is 6 so 6 x 2 = 12. After that you need to find the rest of the sides so you can do 30 - 12 = x, or 12 + x = 30. As a total the answer is 18. Finally you divide 18 by two because there is two sides and you get 9.

The Jefferson Valley Bank once had a separate customer waiting line at each teller window, but it now has a single waiting line that feeds the teller windows as vacancies occur. The standard deviation of customer waiting times with the old multiple-line configuration was 1.8 min. Listed below is a simple random sample of waiting times (minutes) with the single waiting line. Use a 0.05 significance level to test the claim that with a single waiting line, the waiting times have a standard deviation less than 1.8 min. What improvement occurred when banks changed from multiple waiting lines to a single waiting line?
Answer:
There will be sufficient evidence to conclude. A further explanation is provided below.
Step-by-step explanation:
The given values are:
[tex]\sigma=1.8[/tex]
[tex]\alpha=0.05[/tex]
[tex]n=10[/tex]
As we know,
[tex]\bar{x}=\frac{\Sigma x_i}{n}[/tex]
[tex]=\frac{71.5}{10}[/tex]
[tex]=7.15[/tex]
The standard deviation will be:
⇒ [tex]s=\sqrt{\frac{1}{n-1} \Sigma(x_i- \bar{x})^2 }[/tex]
On substituting the values, we get
⇒ [tex]=\sqrt{\frac{1}{10-1} [(6.5-7.15)^2+...(7.7-7.15)^2]}[/tex]
⇒ [tex]=\sqrt{\frac{1}{9} [(6.5-7.15)^2+...(7.7-7.15)^2]}[/tex]
⇒ [tex]=0.477[/tex]
According to the question,
Hypotheses:
[tex]H_o: \sigma=1.8[/tex]
[tex]H_a: \sigma<1.8[/tex]
The test statistic will be:
⇒ [tex]X^2=\frac{(n-1)s^2}{\sigma^2}[/tex]
⇒ [tex]=\frac{(10-1)\times 0.477^2}{1.8^2}[/tex]
⇒ [tex]=\frac{2.0477}{3.24}[/tex]
⇒ [tex]=0.632[/tex]
Thus the above is the correct response.

Solve for the nearest tenth
Solve for the missing side
Answer:
[tex]\Huge\boxed{x=11.8}[/tex]
Step-by-step explanation:
Hello There
cos = adjacent divided by hypotenuse
the adjacent side of the angle that has a measure of 49 is x and the hypotenuse is 18
so
[tex]cos49=\frac{x}{18}[/tex]
once again we want to isolate the variable using inverse operations
to get rid of the 18 we multiply each side by 18
[tex]\frac{x}{18} *=x\\cos49*18=18cos49[/tex]
we're left with
[tex]x=18cos49[/tex]
now we let the calculator do the rest of the work
we end up with
[tex]x=11.80906252[/tex]
our final step would be to round to the nearest tenth
so we can conclude that the x = 11.8

If a five on a dice is rolled 10 times within 50 rolls, how many times would you roll a five if you rolled the dice 300 times?
Answer:
60
Step-by-step explanation:
There are two ways to check that I know.
First way:
Double 50, 10 automatically doubles too.
50x2=100
10x2=20
Then we can multiply the 100 by to equal 300, the 20 also automatically multiplies to equal 60.
100x3=300
20x3=60
Second way:
10 is 20% of 50 we can find that bu multiplying 20% and 50, like this:
20%x50= 10
To find out the answer if the 5 was changed to a 300 we would have to multiply 20% of 300.
20%x300= 60
We've looked at two ways to solve this problem and both ways equal 60. So, therefore, the answer for this question is 60.

Answer:
x = 4
y = 3.5
Step-by-step explanation:
The parallelogram given has opposite sides that are equal in length. Therefore, the diagonals bisect each other into two equal parts respectively.
Thus:
2y = 7
Divide both sides by 2
y = 7/2
y = 3.5
Also,
x + 6 = 10
Subtract 6 from each side
x = 10 - 6
x = 4
A father left 280 acres of land to be divided among his sons Al and Bob in the ratio 4:3, respectively. How many acres should Al receive?
Answer:
160 acres
Step-by-step explanation:
Given data
Total Amount of land= 280 Acres
Ratio=4:3
Total part = 4+3= 7
Applying the part to all method
let AI receive x acres
Then
4/7= x/280
cross multiply
7x= 280*4
7x=1120
x= 1120/7
x= 160
Hence AI will receive 160 acres

4.9x+4.2=9.1, x=1
Explanation for last two:
[tex]-\frac{2}{7}t+5=17[/tex]
Step 1: Subtract 5 from both sides.
[tex]\frac{-2}{7} t+5-5=17-5[/tex]
[tex]\frac{-2}{7} t=12[/tex]
Step 2: Multiply both sides by 7/(-2).
[tex](\frac{7}{-2} )*( \frac{-2}{7}t )= (\frac{7}{-2} )*(12)[/tex]
t=−42
4.9x+4.2=9.1
Step 1: Subtract 4.2 from both sides.
4.9x+4.2−4.2=9.1−4.2
4.9x=4.9
Step 2: Divide both sides by 4.9.
[tex]\frac{4.9x}{4.9} \frac{4.9}{4.9}[/tex]

Keisha is playing a game using a wheel divided into eight equal sectors, as shown in the diagram. Each time the spinner lands on white, she will win a prize. If she spins this wheel twice, what is the probability she will win a prize on both spins? Please show all steps!
Answer:
[tex] \frac{4}{64} [/tex]
Step-by-step explanation:
The spinner is independent (the total won't be effected)
we know there is 2 whites with 8 coloured option.
[tex] \frac{2}{8} [/tex]
we want the probability of getting two whites.
[tex] \frac{2}{8} \times \frac{2}{8} = \frac{4}{64} [/tex]
there is 3 ways to work out probability, fraction, decimal and percentage (i'd personally say fraction is the most easiest)
The probability of Keisha to win a prize on both spins in a game of wheel which is divided in eight equal sectors is 1/16.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
Keisha is playing a game using a wheel divided into eight equal sectors, as shown in the diagram.
Each time the spinner lands on white, she will win a prize. If she spins this wheel twice,
Here, the white is appeared twice in the wheel and the total number of sector in wheel are 8. Thus the probability of first time to come white in the spin is,
[tex]P=\dfrac{2}{8}\\P=\dfrac{1}{4}[/tex]
The conditions are same for the second case. For this case, both result of both the spins of wheel are independent of each other.
Thus, by the chain rule, the probability both spin as white sector appear is,
[tex]P=\dfrac{1}{4}\times\dfrac{1}{4}\\P=\dfrac{1}{16}[/tex]
Thus, the probability of Keisha to win a prize on both spins in a game of wheel which is divided in eight equal sectors is 1/16.

Find the measure of angle x?
Answer:
x = 43 degrees
Step-by-step explanation:
First, you have to see that there is a right angle of 90 degrees. Since that is there, you know that there is 90 degrees in the bottom and right side as well. So all you do in this question is do 90 - 47 to get your answer of 43 degrees.
