Quadrilateral ABCD is inscribed in a circle. Angle B measures 74 degrees,and angle D measures (x-15) degrees.What does x equal?
A-106
B-105
C-91
D-121
pls help asap
Answers
Answer:
121degrees
Step-by-step explanation:
For a quadilateral inscribed in a circle, the sum of its opposite angles is 180degrees. Hence;
<B + <D = 180
x -15 + 74 = 180
x + 59 = 180
x = 180 - 59
x = 121 dgrees
Hence the value of x is 121degrees

If you multiply 200 with 13 you get 2600.
To find the remainder subtract 2612 with 2600 which leaves 12.

Find the first three terms of the series represented by the formula 3(- 2)(n - 1).
Answers
Answer:
0, - 6, - 12
Step-by-step explanation:
To find the first 3 terms, substitute n = 1, 2, 3 into the formula
a₁ = 3(- 2)(1 - 1) = 3 × - 2 × 0 = 0
a₂ = 3(- 2)(2 - 1) = 3 × - 2 × 1 = - 6
a₃ = 3(- 2)(3 - 1) = 3 × - 2 × 2 = - 12
First 3 terms are 0, - 6, - 12

Consider the following hypothesis test: H0: μ1 - μ2 = 0 Ha: μ1 - μ2 ≠ 0 There are two independent samples taken from the two populations: Sample 1 Sample 2 n1 = 81 n2 = 64 Sample average = 110 Sample average = 108 Population standard deviation = 7.2 Population standard deviation = 6.3 What is the value of the test statistic.
Answers
Answer:
The value of the test statistic is [tex]z = 1.78[/tex]
Step-by-step explanation:
Before finding the test statistic, we need to understand the central limit theorem and subtraction of normal variables.
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Subtraction between normal variables:
When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.
Sample 1:
[tex]\mu_1 = 110, s_1 = \frac{7.2}{\sqrt{81}} = 0.8[/tex]
Sample 2:
[tex]\mu_2 = 108, s_2 = \frac{6.3}{\sqrt{64}} = 0.7875[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{s}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, and s is the standard error.
0 is tested at the null hypothesis:
This means that [tex]\mu = 0[/tex]
Distribution of the difference:
[tex]X = \mu_1 - \mu_2 = 110 - 108 = 2[/tex]
[tex]s = \sqrt{s_1^2+s_2^2} = \sqrt{0.8^2+0.7875^2} = 1.1226[/tex]
What is the value of the test statistic?
[tex]z = \frac{X - \mu}{s}[/tex]
[tex]z = \frac{2 - 0}{1.1226}[/tex]
[tex]z = 1.78[/tex]
The value of the test statistic is [tex]z = 1.78[/tex]

The top three oil producers in the United States in a certain year were the Gulf of Mexico, Texas, and Alaska. The three regions were responsible for 64% of the United States oil production. The Gulf of Mexico and Texas combined for 47% of oil production. Texas produced 3% more than Alaska. What percent of United States oil production came from these regions?
Answers
Answer:
27% of United States oil production came from Gulf of Mexico.
20% of United States oil production came from Texas.
17% of United States oil production came from Alaska.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
Gulf of Mexico produced x%.
Texas produced y%.
Alaska produced z%.
The three regions were responsible for 64% of the United States oil production.
This means that:
[tex]x + y + z = 64[/tex]
The Gulf of Mexico and Texas combined for 47% of oil production.
This means that [tex]x + y = 47[/tex].
We use this to find z.
[tex]47 + z = 64[/tex]
[tex]z = 64 - 47 = 17[/tex]
17% of United States oil production came from Alaska.
Texas produced 3% more than Alaska.
Then:
[tex]y = z + 3 = 17 + 3 = 20[/tex]
20% of United States oil production came from Texas.
Gulf of Mexico
[tex]x + y = 47[/tex]
[tex]x = 47 - y = 47 - 20 = 27[/tex]
27% of United States oil production came from Gulf of Mexico.

Parker just started a running plan where he runs 7 miles the first week and then
increases the number of miles he runs by 10% each week. If he keeps up this plan for
15 weeks, how many total miles would Parker have run, to the nearest whole
number?
Answers
Answer:
Parker would have run 29 miles in the 15th week.
Step-by-step explanation:
Since Parker just started a running plan where he runs 7 miles the first week and then increases the number of miles he runs by 10% each week, to determine, if he keeps up this plan for 15 weeks, how many total miles would Parker have run, to the nearest whole number, the following calculation should be performed:
7 x 1.1 ^ 15 = X
7 x 4.1772 = X
29.24 = X
Therefore, Parker would have run 29 miles in the 15th week.
