Mathematics
1 answer:
mina [271]4 years ago
8 0

Answer:

Yes

Step-by-step explanation:

If you take a  look at a number line, the absolute value is the distance any number on the number line is farther away from 0. Distance is always positive, so our absolute value is always 0.

Compute z-score. Given ~ n(12,2.5),find z score when x =17
Anestetic [448]

Answer:

The desired z-score is 2.

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.

n(12,2.5)

This means that \mu = 12, \sigma = 2.5

z score when x =17

This is Z when X = 17. So

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

Z = \frac{17 - 12}{2.5}

Z = 2

The desired z-score is 2.

Anna11 [10]

Answer:

x= -2 —> y= 4

x = -1 —> y = 1

x = 0 —> y = – 4

x = 1 —> y = – 11

x = 2 —> y = – 20

fatima wants to find the value of sin theta, given cot theta equals 4/7. which identity would be best for fatima to use?
choli [55]
We know that
1+cot ²∅=csc² ∅
cot ∅=4/7
so
1+(4/7)²=csc² ∅
csc² ∅=1+(16/49)
csc² ∅=(65/49)
csc ∅=(√65)/7

remember that
csc ∅=1/sin ∅
sin ∅=1/csc ∅------> sin ∅=7/√65-----> sin ∅=(7√65)/65

the answer is
the best identity to find sin ∅ is
1+cot ²∅=csc² ∅
