This package of sliced cheese cost $2.97. How much would a package with 18 slices cost at the same price per slice

Remember that the radicand (the area under the root sign) must be positive or zero for a radical with an even index (like the square root or fourth root, for example). This is because two numbers squared or to the fourth power, etc. cannot be negative, so there are no real solutions when the radicand is negative. We must restrict the domain of the square-root function.

If the domain has already been restricted to $x \geq -11$ , we can work backwards to add 11 to both sides. We see that $x+11$ must be under the radicand, so the answer is A.

The mean of a certain set of measurements is 27 with a standard deviation of 14. The distribution of the

Talja [164]

Answer:

Exactly 16%.

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

The mean of a certain set of measurements is 27 with a standard deviation of 14.

This means that $\mu = 27, \sigma = 14$

The proportion of measurements that is less than 13 is

This is the p-value of Z when X = 13, so:

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

$Z = \frac{13 - 27}{14}$

$Z = -1$

$Z = -1$ has a p-value of 0.16, and thus, the probability is: Exactly 16%.

HELP!!!!!!! I WIL MAKE MARK YOU BRAINLIAST

Finger [1]

Answer:

M is 1.5

Step-by-step explanation:

Use M = 1/O

Replace 1 with a letter such as K

So you use M = K/O

Substitute values

0.5 = K/6

To get K times 0.5 by 6

You get 3

So K=3

Use the equation from the start to find M

M=3/2

M IS 1.5

The rays OM , ON , and OP in the figure, coincide at time t=0. At the same instant of time OM and OP rotate in the plane about p

dangina [55]

Note:

Note that the shape is a circle(s), as they all will rotate until they coincide. However, they are rotating towards each other

Step-by-step explanation:

One is rotating at 3°, while the other is rotating at 6°. We do not need to both with ON, for the question is not asking for that segment.

A circle has 360° To solve this, we must know that "the other" must complete a circle and overtake the other one.

So. First, solve for the circle (360°)

360/6 = 60

It takes one of the rays to rotate a full circle 60 seconds.

The other, at the same time, has rotated half way, as:

360/3 = 120

--------------------------------------------------------------------------------------------

Remember that one of the rays (the one that is faster), completes it's turn twice as fast. This means that you must solve for the mean:

(60 + 120)/2 = 180/2 = 90

90 seconds will be used until one overtakes the other
