Goryan [66]4 years ago

Answer:

Z for males = 2.57

Z for females = 2.06

male value is more extreme

Step-by-step explanation:

Z score represents how many standard deviation you are from the mean.

The formula is:

Z = (Value - Mean)/(ST. DEV.)

For newborn males:

Z = (1500-3292.4)/697.5 = 2.57

For newborn females:

Z = (1500-3000.6)/727.9 = 2.06

Z score for newborn males is bigger, therefore 1500 is more extreme relative to the group

Two-fifths of one less than a number is less than three-fifths of one more than that number. What numbers are in the solution se
Soloha48 [4]
Let us say, the number is "a"

one less than "a" is ... well a - 1
2/5 of that will be... well, 2/5 * ( a - 1)

one more than "a" is... well a + 1
3/5 of that is.. hmmm 3/5 * (a + 1)

now, we're told that, the first expression is "less than" the second one, thus

\bf \cfrac{2}{5}(a-1)\ \textless \ \cfrac{3}{5}(a+1)

solve for "a", or make it "x" if you wish, same thing anyway

What is X= to and what does Y= to?
Jet001 [13]

Step-by-step explanation:

Straight line = 180 °

5x + 78 = 180

5x = 180 - 78

5x = 102

x = 20.4

and y = 78 ° because y is an opposite angle of 78 °

Degger [83]
Answer:
43 miles per hour

Step-by-step explanation:

We know that in Cherokee County, the speed tickets amounts are calculated on the basis of $17 for each mile above the speed limit.
Since Kirk was fined $221, we can easily calculate the excess speed he was caught at by dividing $221 by $17/mile, which gives us 13 miles.

Since he was caught in a zone where the posted speed limit was 30, and that he exceeded it by 13 miles per hour... we know he was going at 43 miles per hour.

I hope this helps you :)
