FOR 15 POINTS I WILL GIVE BRAINLEST IF YOU ARE CORRECT! What is the solution to the system that is created by the equation y = 2

goblinko [34]

The solution point is (4,2).

Step-by-step explanation:

Equation of straight line passing through the points (0,0) and (4,2) is given by

⇒ 2y = x ............ (1)

And the other straight line is y = - x + 6 .............. (2)

Now, solving equations (1) and (2) we get, y = - 2y + 6

⇒ 3y = 6

⇒ y = 2

And from equation (1) we get, x = 2y = 4

Therefore, the solution point is (4,2). (Answer)

A population of values his normal distribution with men equal to 27.6 and standard deviation equal 39.4 do you intend to draw a

Alecsey [184]

Answer:

The mean of the distribution of sample means is 27.6

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 27.6

Standard Deviation, σ = 39.4

We are given that the population is a bell shaped distribution that is a normal distribution.

Sample size, n = 173.

We have to find the mean of the distribution of sample means.

Central Limit theorem:

It states that the distribution of the sample means approximate the normal distribution as the sample size increases.
The mean of all samples from the same population will be approximately equal to the mean of the population.

Thus, we can write:

$\mu_{\bar{x}} = \mu = 27.6$

Thus, the mean of the distribution of sample means is 27.6

Suppose a hot air balloon begins descending at a rate of 30ft/min from an elevation of 1250ft. Write an equation to model the ho

galina1969 [7]

Base elevation is 1250 ft
rate is 30 per minute 30m
so, h = 1250 - 30m
as an inclusion, 30 ft per minute is also like 0.5 per second like 1250 - 0.5s
1250/30 means it would be about 42 minutes once it touches the ground.
