Answer:

x=7.5

Step-by-step explanation:

To solve this, cross multiply

3/4=x/10

4*x=3*10

4x=30

Divide by 4 on both sides

x=7.5

Hope this helps! :)

Answer:

x=7.5

Step-by-step explanation:

3/4 is 75% so therefore x/10 has to be the same

75% of 10 is 7.5

So therefore x=7.5

What are the greatest common factor for 45 and 60

viva [34]

To find the Greatest Common Factor of 45 and 60, we do the following:

Find the Factors of 45 & 60.
45: 1, 3, 5, 9, 15, 45
60: 1, 2, 3, 4, 5, 6,10, 12, 15, 20, 30, 60

As you can see, 15 is the greatest common factor.

Which point is on the graph of f(x) = 2*5^x

vodomira [7]

Answer:

Option B (1,10)

Step-by-step explanation:

we have

$f(x)=2(5^x)$

we know that

If a ordered pair is on the graph of f(x) then the ordered pair must satisfy the function f(x)

Verify each case

case A) (0,0)

For x=0

$f(x)=2(5^0)\\f(x)=2(1)=2$

Compare the value of f(x) with the y-coordinate of the ordered pair

$2\neq 0$

therefore

The ordered pair is not on the graph of f(x)

case B) (1,10)

For x=1

$f(x)=2(5^1)\\f(x)=2(5)=10$

Compare the value of f(x) with the y-coordinate of the ordered pair

$10=10$

therefore

The ordered pair is on the graph of f(x)

case C) (0,10)

For x=0

$f(x)=2(5^0)\\f(x)=2(1)=2$

Compare the value of f(x) with the y-coordinate of the ordered pair

$2\neq 10$

therefore

The ordered pair is not on the graph of f(x)

case D) (10,1)

For x=10

$f(x)=2(5^{10})\\f(x)=2(9,765,625)=19,531,250$

Compare the value of f(x) with the y-coordinate of the ordered pair

$19,531,250\neq 1$

therefore

The ordered pair is not on the graph of f(x)

Lady_Fox [76]

Answer: 669

Step-by-step explanation:

Given, In a Gallup poll of randomly selected adults, 66% said that they worry about identity theft.

i.e. The proportion of adults said that they worry about identity theft. (p) = 0.66

Sample size : n= 1013

Then , Mean for the sampling distribution of sample proportion = np

= (1013) × (0.66)

= 668.58 ≈ 669 [Round to the nearest whole number]

Hence, the mean of those who do not worry about identify theft is closest to 669 .
