Answer:
x=50
Step-by-step explanation:
It is a line so it should be 180 degrease. You already have two of the angles and to find the third (x) you just need to subtract them from 180. 180-105=75, and 75-25 is 50, so x is 50.
Answer: x=50 degree
Step-by-step explanation: angle in a straight line is equal to 180 degrees.
Given;
25 degrees &
105 degrees.
180– (105+25)
180– 130
= 50degrees

Identify the terminal point for a 30° angle in a unit circle.
The terminal point of the unit circle (cos θ, sine θ) for 30° is ( √3/2 , 1/2 ).
What is the terminal point?"The terminal point is the ray that has been rotated around the origin to form an angle with the stationary ray which is the initial side of the angle. They are sine and cosine values of the most common acute-angle measures".
For the given question,
Angle = 30°
The terminal point on the unit circle has the cosine as x -coordinate and the sine as y - coordinate are mostly acute-angle measures.
Here, θ = 30°
The x-coordinate is cos 30° = [tex]\frac{\sqrt{3} }{2}[/tex]
The y-coordinate is sin 30° = [tex]\frac{1}{2}[/tex]
Hence we can conclude that the terminal point for 30° is ( √3/2 , 1/2).

Step-by-step explanation:
is -3.8 bigger less than or equal to -4 1 / 2
Answer:
bigger
Step-by-step explanation:
Answer:
Bigger
Step-by-step explanation:
-3.8 is bigger because negative numbers closer to 0 are actually bigger than negative numbers farther away.
If [tex]-4\frac{1}{2}[/tex] is broken down into simpler form it becomes -9/2 which reduces to -4.5 in decimal form. -4.5 is farther away from 0 on a number line thus it is smaller. Thus -3.8 > -4.5

The residuals are normally distributed. b. The model over predicts the value of the dependent variable for small values and large values of the independent variable. c. The model fails to capture the relationship between the variables accurately, and there may exist nonlinear relationship. d. The residuals have a constant variance.
Answer: Hello the scatter plot related to your question is missing attached below is the scatter plot
answer : The model fails to capture the relationship between the variables accurately, and there may exist nonlinear relationship ( C )
Step-by-step explanation:

Kent is 5 years younger than Robert. The sum of their ages is 39. What are their ages?
Answer:
Kent is 34 and Robert is 44 I'm not sure tho hope it helps
Answer:
Robert is 17 years old
Kent is 13 years old
Step-by-step explanation:
Alright, let's say that Robert is X years old, and Kent is X - 5 Years old, since he is 5 years younger. Since their ages together add up 39 years old, set these values next to one another.
x + x + 5 = 39
Add Like Terms
2x + 5 = 39
Cancel out the 5
2x = 34
Divide by 2
x = 17
With this, x is 17. This means that Robert is 17 years old since his age was x. With Kent he is 13 years old since 17 - 5 = 13.

Fay read an article that said 26% of Americans can speak more than one language. She was curious if this
figure was higher in her city, so she tested H, : p=0.26 vs. H : p > 0.26, where p represents the
proportion of people in her city that can speak more than one language.
She found that 40 of 120 people sampled could speak more than one language. The test statistic for these
results was 2 1.83.
Assuming that the necessary conditions are met, what is the approximate P-value for Fay's test?
You may round to three decimal places.
P-value
Answer:
0.0336
Step-by-step explanation:
the hint says so
According to the result of the test statistic, the approximate p-value for Fay's test is of 0.034.
How to find the p-value of a test?
It depends on the test statistic z, as follows.
For a left-tailed test, it is the area under the normal curve to the left of z, which is the p-value of z.For a right-tailed test, it is the area under the normal curve to the right of z, which is 1 subtracted by the p-value of z.For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is 2 multiplied by 1 subtracted by the p-value of z.In this problem, we are testing if the proportion is greater than a value, hence it is a right-tailed test.
The test statistic is z = 1.83, which has a p-value of 0.966.
1 - 0.966 = 0.034.
Hence, the approximate p-value for Fay's test is of 0.034.

In a lab experiment, 2400 bacteria are placed in a petri dish. The conditions are such
that the number of bacteria is able to double every 19 hours. How long would it be, to
the nearest tenth of an hour, until there are 3300 bacteria present?
Answer:
It takes 8.7 hours for there to be 3300 bacteria present.
Step-by-step explanation:
Exponential equation for population growth:
The exponential equation for population growth is given by:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(0) is the initial population and r is the growth rate.
2400 bacteria are placed in a petri dish.
This means that [tex]P(0) = 2400[/tex]
So
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]P(t) = 2400(1+r)^t[/tex]
The conditions are such that the number of bacteria is able to double every 19 hours.
This means that [tex]P(19) = 2P(0)[/tex]. We use this to find 1 + r.
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]2P(0) = P(0)(1+r)^{19}[/tex]
[tex](1+r)^{19} = 2[/tex]
[tex]\sqrt[19]{(1+r)^{19}} = \sqrt[19]{2}[/tex]
[tex]1 + r = 2^{\frac{1}{19}}[/tex]
[tex]1 + r = 1.03715504445[/tex]
So
[tex]P(t) = 2400(1+r)^t[/tex]
[tex]P(t) = 2400(1.03715504445)^t[/tex]
How long would it be, to the nearest tenth of an hour, until there are 3300 bacteria present?
This is t for which [tex]P(t) = 3300[/tex]. So
[tex]P(t) = 2400(1.03715504445)^t[/tex]
[tex]2400(1.03715504445)^t = 3300[/tex]
[tex](1.03715504445)^t = \frac{3300}{2400}[/tex]
[tex]\log{(1.03715504445)^t} = \log{\frac{33}{24}}[/tex]
[tex]t\log{1.03715504445} = \log{\frac{33}{24}}[/tex]
[tex]t = \frac{\log{\frac{33}{24}}}{\log{1.03715504445}}[/tex]
[tex]t = 8.7[/tex]
It takes 8.7 hours for there to be 3300 bacteria present.

2592 cubic units. What is the height of the cone?
Answer:
use formula,
volume=1/3hπ[tex]r^{2}[/tex]
2592=1/3*h*3.14*(18)^2
2592=1/9.42h*324
2592=1/3050.08h
