Answer:

Yes,

2 and 5

Step-by-step explanation:

A function has an inverse if and only if it is one to one.

To tell if this equation is a function, and to tell if it is one to one, we must do the vertical line test, and the horizontal line test.

It passes the vertical line test and the horizontal line test.

Therefore it has an inverse.

To get the inverse of this equation, we have to know that inverses are reflections over Y = X. So if we plot that line, we can have an idea of where the inverse would be.

f^-1 (0) = 2

f^-1 (3) = 5

The easiest way to do this... is to know that the inverse equation just flips all the coordinates.

(0,1) -> (1,0)

So... if they give you the Y intercept the (0 and the 3) go look at where the line crosses X! I mean, why not? They gave you half the inverse coordinate point an

Shelia's measured glucose level one hour after a sugary drink varies according to the normal distribution with μ = 117 mg/dl and
TiliK225 [7]

Answer:

The level L such that there is probability only 0.01 that the mean glucose level of 6 test results falls above L is L = 127.1 mg/dl.

Step-by-step explanation:

To solve this problem, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central limit Theorem

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, a large sample size can be approximated to a normal distribution with mean \mu and standard deviation \frac{\sigma}{\sqrt{n}}

In this problem, we have that:

\mu = 117, \sigma = 10.6, n = 6, s = \frac{10.6}{\sqrt{6}} = 4.33

What is the level L such that there is probability only 0.01 that the mean glucose level of 6 test results falls above L ?

This is the value of X when Z has a pvalue of 1-0.01 = 0.99. So X when Z = 2.33.

Z = \frac{X - \mu}{\sigma}

By the Central Limit Theorem

Z = \frac{X - \mu}{s}

2.33 = \frac{X - 117}{4.33}

X - 117 = 2.33*4.33

X = 127.1

The level L such that there is probability only 0.01 that the mean glucose level of 6 test results falls above L is L = 127.1 mg/dl.

Which line is the graph of y= -2x+2? D B A C
abruzzese [7]
The answer is b because in y=mx+c, m is the gradient and c is the y-intercept. since the y-intercept is 2, we can safely discard d as an option. when a gradient is -2, it is a negative graph which means a and c is out. so, you’re left with b!

It takes 12 apples to make 2 cups of apple sauce. If 72 apples are used, what is the greatest number of cups of apple sauce that
Klio2033 [76]

Answer:

12

Step-by-step explanation:

If 12 apples makes 2 cups, we can assume that 6 apples make 1 cup.

Take the number of apples and divide it by 6 in order to find out the number of cups that can be made.
