7 : 5 = 7x : 5x

7x + 5x = 12x

12x = 48 ⇒ x = 48:12 = 4

7x = 7 · 4 = 28
5x = 5 · 4 = 20

Answer: 28 : 20

Write the ratio as a fraction, a decimal, and a percent.<br> 51:75
irina [24]
51:75

This is the same as 51/75.

Simplify by dividing 3 to the numerator and denominator:

17/25

Divide this to get a decimal:

17 / 25 = 0.68

Now multiply by 100 to get a percent:

0.68 * 100 = 68%

If f(x)=x^2-3x,find f(-18). Show work
scoundrel [369]
Answer: 378

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

Work Shown:

f(x) = x^2 - 3x
f(x) = ( x )^2 - 3*( x )
f(-18) = ( -18 )^2 - 3*( -18 ) ... replace every x with -18; now use PEMDAS
f(-18) = 324 - 3*( -18 )
f(-18) = 324 + 54
f(-18) = 378

Using the information regarding the proportion of work time linguists study a new language, choose the correct conclusion for th
Vlada [557]

Answer:

The  correct option is  B

Step-by-step explanation:

From the question we are told that

  The null hypothesis is  H_o : p = 0.10

   The alternative hypothesis is  H_a  :  p >  0.10

   The  p-value  is  p-value  =  0.09

   The  level of  significance is  \alpha = 0.025

   

From the given values p-value >  \alpha so we fail to reject the null hypothesis

So there is NOT sufficient evidence to conclude the proportion of work time linguists study a new language is more than 10%.
