How?<br> In the world do you do this it’s very confusing
OleMash [197]

So this triangle is considered a "special triangle". The 30-60-90 triangle rule states that if the short leg is n, then the hypotenuse is 2n and the long leg is n√3.

In this case, since the short leg is 7, x = 14 and y = 7√3. The correct answer that has this is B.

The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of 0°C at the freezing
Serjik [45]

Answer:

c) -1.75°

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.

Mean of 0, standard deviation of 1:

This means that \mu = 0, \sigma = 1

Find the reading that separates the bottom 4% from the others.

This is the 4th percentile, which is X when Z has a p-value of 0.04, so X when Z = -1.75.

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

-1.75 = \frac{X - 0}{1}

X = -1.75*1

X = -1.75

The correct answer is given by option c.

If 10 + 5x is 12 more 8, what is the value of 3x?
vredina [299]

Answer:

3x=6

Step-by-step explanation:

10 + 5x =8+12

10 +5x = 20

Subtract 10 from each side

10-10+5x=20-10

5x= 10

Divide by 5

5x/5 = 10/5

x = 2

We want 3x

3(2) = 6

3x=6
