Answer:

We need to evaluate this: [(-16)+4] / [(-2)+5]

First, we do the brackets:

[(-16)+4]
[(-2)+5]

[(-16)+4] = -16 + 4 = -12

[(-2) + 5] = -2 + 5 = 3

Now, we only need to divide, as we have calculated both brackets:

-12/3 = -4

(Remember that when dividing a negative number by a positive one, we always obtain a negative)

So the result is -4

Our focus here will be on the figures inside () to start on with; considering these figures are - & + accordingly:-

( (-16) + 4 ) ÷ ( (-2) + 5 )
= (-16 + 4) ÷ (-2 + 5)
= (-12) ÷ (+3)
= -4

So, the answer is (-4)

the standard normal curve shown below models the population distribution of a random variable. What proportion of the values in

LiRa [457]

Answer:

0.3175 or 31.75%

Explanation:

Please, find attached the diagram with the standard normal curve for this problem.

The two z-scores indiated are z = - 1.25 and z = 0.80

The proportion of the values in the population that does note lie between the two z-scores indicated on the diagram is equal to the the areas below the curve to the left of z < -1.25 and to the right z > 0.80

The areas to the left or to the right of the z-scores are found in the tables of standard normal cummulative probabilities.

There are tables that show the cummulative probability to the left of the z-scores and tables that show the cummulative probability to the right of the z-scores.

Using a table for the cummulative probatility to the right of the z-score = 0.80 you find:

P(Z > 0.80) = 0.2119

Using the symmetry property of the standard normal distribution, P(Z<-1.25) = P(Z>1.25).

Thus, using the same table: P(Z>1.25) = 0.1056

Hence, P(Z<-1.25) + P(Z>0.8) = 0.1056 + 0.2119 = 0.3175.

Therefore, 0.3175 or 31.75% of the values in the population does not lie between the two z-scores indicated on the diagram.

Which inequality is true? 2/5<7/12 2/3<1/8 1/4>7/10 3/10>5/8

mr_godi [17]

Answer:

2/5<7/12 is true

Step-by-step explanation:

2/5 multiply the numerator and denominator by 12 you get 24/60

7/12 multiply the numerator and denominator by 5 you get 35/60

24/60 IS less than 35/60

Two sides of an acute triangle measure 5 inches and 8 inches. The length of the longest side is unknown.

nordsb [41]

The greatest whole possible whole number length of the unknown side is 9 inches

Solution:

Two sides of an acute triangle measure 5 inches and 8 inches

The length of the longest side is unknown

We have to find the length of unknown side

The longest side of any triangle is a hypotenuse

For a acute triangle we know:

If c is the longest side of a acute triangle, a and b are other two sides of a acute triangle then the condition that relates these three sides are given as:

$c^2$
