What is the value of x in the figure below? Show your work(3 Points). Correct Answer (2 Points)
Answer:
Step-by-step explanation:
BP ^2 = AP*PC
AP = 5
PC = 8
BP^2 = 5 * 8
BP^2 = 40
Don't bother taking it down any further. We are going to need it as it is.
BP^2 + PC^2 = x^2
BP^ = 40
PC^2 = 8^2 = 64
40 + 64 = x^2
104 = x^2
sqrt(x^2) = sqrt(104)
x = 2 sqrt(26) or
x = 10.198

Consider a sample of 52 football games where 32 of them were won by the home team use a 0.01 significance level to test the claim that the probability that the home team wins is greater than one half
According to the information given, it is found that:
The hypothesis tested are:C. [tex]H_0: p = 0.5[/tex], [tex]H_1: p > 0.5[/tex]
The test statistic is z = 1.66.The p-value of the test is of 0.0485.The conclusion is:Fail to reject [tex]H_0[/tex], as there is not sufficient evidence to conclude that the probability that the home team wins is greater than one half.
At the null hypothesis, it is tested if home teams win half their games, that is, if the proportion is of 0.5, hence:
[tex]H_0: p = 0.5[/tex]
At the alternative hypothesis, it is tested if home teams win more than half their games, that is, if the proportion is of more than 0.5, hence:
[tex]H_1: p > 0.5[/tex]
The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion. p is the proportion tested at the null hypothesis. n is the sample size.For this problem, the parameters are:
[tex]p = 0.5, n = 52, \overline{p} = \frac{32}{52} = 0.6154[/tex]
Hence, the value of the test statistic is:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.6154 - 0.5}{\sqrt{\frac{0.5(0.5)}{52}}}[/tex]
[tex]z = 1.66[/tex]
The test statistic is z = 1.66.
The p-value is the probability of finding a sample proportion above 0.6154, which is 1 subtracted by the p-value of z = 1.66.
Looking at the z-table, z = 1.66 has a p-value of 0.9515.1 - 0.9515 = 0.0485.
The p-value of the test is of 0.0485.
Since the p-value is greater than 0.01, the conclusion is:
Fail to reject [tex]H_0[/tex], as there is not sufficient evidence to conclude that the probability that the home team wins is greater than one half.

Find m Help me solve it please!!!!!!!!!!!!!
Answer:
56°
Step-by-step explanation:
1. the rule is: m(DCE)+m(DEC)+m(CDE)=180;
2. m(DCE)=180-(7x-2)=182-7x;
m(DEC)=180-(4x+33)=147-4x;
m(CDE)=180-(9x-31)=211-9x;
3. after the substitution all the angles (item 2) into the rule (item 1):
182-7x+147-4x+211-9x=180;
20x=360;
x=18;
4. if x=18, then filally, m(DCE)=182-7*18=56°.

Hong's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Hong $5.80 per pound, and type B coffee costs $4.20 per pound. This month's blend used four times as many pounds of type B coffee as type A, for a total cost of $700.60 . How many pounds of type A coffee were used?
Answer:
31 Pounds
Step-by-step explanation:
Let x = the number of lbs of Type A coffee.
We know that this month's blend used 4 times as many pounds of type B coffee as type A coffee.
Total lbs of coffee = x + 4x
The total cost then is:
($ cost for Type A)(x) + ($ cost for Type B)(3x) = $700.60
$5.80x + $4.20(4x) = $700.60
$5.80x + $16.8x = $700.60
$22.6x = $700.60
x = 31 lbs
Therefore they where 31 pounds of type A coffee used.
Imagine that you have a bag with 2 red blocks, 3 blue blocks, 4 green blocks, and 1 yellow block inside.
You plan to make one draw from the bag.
A Find the probability of getting a green block or a blue block. p(blue or green)=??? (Do not Simplify any Fraction)
you plan on making two draws from the bag (replacing the first)
B Find the probability of getting a green block then a blue block. (order matters) p(green then blue) = ???
C Which is more likely to happen? A or B? Write the letter down.
Answer:
it’s B
Step-by-step explanation:
Answer:
Information given
3 blue
2 red
4 green
1 yellow
Total= 10
For (1) for the probability of a green OR blue blocks you jsut gotta add up green and blue. 4+3=7 And 10 blocks in total so 7/10 chance
For (b) you find the probability of a green which is 4/10 and then a blue which is 3/10. So assumingg you draw twice you have 4/10*3/10 which is 12/100 chance of getting that order.
Well of course b is most likely to happen because its the most Chances.
7/10 > 12/100
