Answer:
csc theta = 25/7
Step-by-step explanation:
I believe you meant the Greek character theta, not 0. Note that sin 0 = 0, which is definitely not equal to 7/25.
Rewriting the given info, we obtain:
sin theta = 7/25 find csc theta
The csc function is the reciprocal of the sin function. Therefore,
if sin theta = 7/25, then csc theta = 25/7

Find the slope and y-intercept from the following graph of a linear equation.
Answer:
A
Step-by-step explanation:
The equation of line is y= -4x -23
What is slope- intercept form?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.
The slope of the line is the ratio of the rise to the run, or the rise divided by the run, therefore the change in y coordinate with regard to the change in x coordinate may be expressed as follows. In the coordinate plane, it describes the slope of the line.
Given:
We can take the coordinates from the given graph as (0, 3) and (2, -5)
Now, the slope = (-5 - 3)/ (2 - 0)
slope= -8/ 2
slope= -4
Now, using the point- slope form
(y - [tex]y_1[/tex]) = m(x - [tex]x_1[/tex])
(y- (-3))= -4( x- (-5))
y+3 = -4(x+5)
y+ 3= -4x - 20
y= -4x -23
Hence, the equation of line is y= -4x -23.

Which ordered pair is a solution to the system of inequalities?
y > 3x
y <2 +5
The ordered pair which is the solution of the given inequalities is (A) (1,5).
What are inequalities?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made. A difference between two values indicates whether one is smaller, larger, or simply not equal to the other. If a and b are equal, then an is greater than b.So, to find the correct values we need to use the hit-and-trial method:
Then, taking (1, 5):
y > 3x5 > 3(1)5 > 3 (Satisfied)Similarly,
5 ≤ x + 55 ≤ 1 + 55 ≤ 6 (Satisfied)So, option (A) (1, 5) is correct.
Therefore, the ordered pair which is the solution of the given inequalities is (A) (1, 5).

A poll agency reports that 45% of teenagers aged 12-17 own smartphones. A random sample of 152 teenagers is drawn. Round your answers to four decimal places as needed. Part 1 out of 6 Find the mean The mean il ESSENEN IN
Answer:
Mean = 0.45
Standard deviation = 0.04035
Step-by-step explanation:
This is actually a very simple problem.
The question gives us the report that 45% of the teenagers in the age bracket own smartphones.
P = mean = 45%
Therefore the mean is 0.45.
I will go ahead to help you calculate the standard deviation.
√p(1-p)/n
n = 152
P = 0.45
√0.45(1-0.45)/152
= √0.45(0.55)/152
= √0.2475/152

Coach Matta ran 3 laps in 180 seconds. Which of the following is an equivalent rate of running?
2 laps in 130 seconds
5 laps in 215 seconds
1 lap in 60 seconds
6 laps in 130 seconds
Answer:
1 lap in 60 seconds
Step-by-step explanation:
This is the answer because:
1) Think of it as ratios or fractions
Ratio: 3:180
2) Next, we have to find something equivalent. Since 3 can only be multiplied by one or itself, we have to dived 3 by 3.
3) 3 divided by 3 is 1
2) 180 divided by 3 is 60
4) This equals to 1:60
Therefore, the answer is 1 lap in 60 seconds

In triangle RST, m∠T is 5° more than m∠R, and m∠S is 10° less than m∠T. What is the measure of each angle?
Answer:
R=60
S=55
T=65
Step-by-step explanation:
[tex]\boldsymbol{m\angle R, m\angle S, m\angle T}[/tex] are equal to [tex]\boldsymbol{60^{\circ},55^{\circ},65^{\circ}}[/tex] respectively.
According to angle sum property of a triangle, sum of all angles of a triangle is equal to [tex]\boldsymbol{180^{\circ}}[/tex]
Let [tex]m\angle R=x[/tex]
As [tex]m\angle T[/tex] is [tex]5^{\circ}[/tex] more than [tex]m\angle R[/tex],
[tex]m\angle T=5^{\circ}+m\angle R[/tex]
[tex]\boldsymbol{m\angle R=m\angle T-5^{\circ}}[/tex]
Also,
[tex]m\angle S[/tex] is [tex]10^{\circ}[/tex] less than [tex]m\angle T[/tex],
[tex]\boldsymbol{m\angle S=m\angle T-10^{\circ}}[/tex]
So,
[tex]\boldsymbol{m\angle R+m\angle S+m\angle T=180^{\circ}}[/tex]
[tex]m\angle T-5^{\circ}+m\angle T-10^{\circ}+m\angle T=180^{\circ}[/tex]
[tex]3m\angle T-5^{\circ}-10^{\circ}=180^{\circ}[/tex]
[tex]m\angle T=\frac{195^{\circ}}{3}[/tex]
[tex]\boldsymbol{=65^{\circ}}[/tex]
[tex]m\angle R=65^{\circ}-5^{\circ}[/tex]
[tex]\boldsymbol{=60^{\circ}}[/tex]
[tex]m\angle S=65^{\circ}-10^{\circ}[/tex]
[tex]\boldsymbol{=55^{\circ}}[/tex]
