Which rays form the sides of IHG
blagie [28]

Answer:

A and C

Step-by-step explanation:

When talking about a ray, the end of the arrow must start at the letter representing the endpoint and the head must be near where the arrow passes through.

In this case, the endpoint is H of both rays, so the end of the arrow has the letter H under it, which leaves only A and C, but let's go further. The head has to be above the nearest point it passes through, and in this case, the left ray passes through I, which makes one of the rays. So the left ray is written as HI with the arrow facing right. The second one, following the guidelines above, has to be HG, with the arrow facing right. Both of these are seen in choices A and C, meaning those are your answers.

Hoped this helps and vote Brainliest, Thx :)

A line passes through the point (0,−4) and has a slope of −3/7.
Sidana [21]
Well, point slope is y - y1 = m(x-x1) So A and D are out. And the negative would cancel each other out for a positive, answer being, B.

Nataly [62]

Answer:

0.002

Step-by-step explanation:

We need to estimate the standard error of the mean, so we can use it as a standard deviation of the sample of 50 males.

Standard error of the mean = standard deviation/√n

Standard error of the mean = 32/√50 = 4.52

Now we can use this Standard error of the mean to estimate z as follows:

Z = (x – mean)/standard deviation

Z = (190-177)/4.52

Z = 2.87

Using  a Z table we can find probability that mean is under 190

P (z<190)= 0.998

For the probability that the mean exceed 190 lbs we substract from 1

P(z>190) = 1 - 0.998 = 0.002

Lilly is a pizza driver. Lilly has to make 4 deliveries.
Veronika [31]

Answer:

23 min 30 sec

Step-by-step explanation:

First, you add 35 + 14 + 18 + 27 which is 94.
Next, you divide 94 by the number of deliveries there were. Which is 4.
94/4 = 23.5.
So your answer would be 23 minutes and 30 seconds.

I Hope This Helped :D
