Answer:

y = 45

Step-by-step explanation:

Given that the x- coordinate of the point on the line is x = 4

To find the corresponding y- coordinate, substitute x = 4 into the equation.

y = 12x - 3 = (12 × 4) - 3 = 48 - 3 = 45

Thus the point is (4, 45 )

a circle has a circumstance of 20. it has an arc on length 4. what is the central angle of the arc in degrees?

erastovalidia [21]

Answer:

∠72°.

Step-by-step explanation:

If a circle has a circumference of 20 and an arc with a length of 4, we can simply set up a ratio to determine the angle of the arc in degrees:

$\frac{4}{20} = \frac{x}{360}$

Cross multiply:

$1440 = 20x\\$

Divide both sides by '20':

x = 72°.

Therefore, the measure of the central angle of the arc is ∠72°.

Pls help With this question thank you

Lapatulllka [165]

Answer:

$CD=4 \text{ cm }$

Step-by-step explanation:

We have a similarity of triangles. Once the side BC and ED are parallel,

$\frac{BC}{AC} =\frac{ED}{AD}$

$\frac{10}{AC} =\frac{5}{4}$

Once $AC=AD+CD \Rightarrow AC=4+CD$

$\frac{10}{4+CD} =\frac{5}{4}$

$5CD+20=40$

$5CD=20$

$CD=4 \text{ cm }$

Fitness experts advise people who want to lose weight to drink protein shakes after workout sessions, because it helps build mus

Artemon [7]

Answer:

Part A

The probability of the treatment groups mean being greater than the control group mean by 8points or more = (26+8+2)/1000 = 0.036

Part B

Yes, the result is statistically significant because the probability of the difference being 8point or more is less than 5% significant level

Part C

The answers is 0.036 means that there is a very little chance of obtaining difference of 8points or more by random chance. So, if the difference between treatment group mean and control group mean is at least 8 , then the result is significant which means protein shaken is actually helpful in speeding up the weight-10 process
