The value of 3 in 46.132 is how many times the value of the 3 in 8.553 A 10 B 1 C 1/10

kifflom [539]

Answer:

The value of 3 in 46.132 is 10 times the value of 3 in 8.553.

Step-by-step explanation:

The value of 3 in 46.132 is in hundredth's place.

The value of 3 in 8.553 is in thousandths place.

We can write as :

For 46.132, its value is $\dfrac{3}{100}$ and for 8.553 its value is $\dfrac{3}{1000}$ .

Taking,

$\dfrac{\dfrac{3}{100}}{\dfrac{3}{1000}}=10$

So, the value of 3 in 46.132 is 10 times the value of 3 in 8.553. Hence, the correct answer is A.

A research organization reported that 41 percent of adults who were asked to describe their day responded that they were having

Neporo4naja [7]

Answer:

B) No, because the p-value is greater than any reasonable significance level

Step-by-step explanation:

H-null: p = 0.41

H-alt: p =/= 0.41

1 proportion Z test

On a calculator: stat + tests + 5

p: .41

x: 245

n: 600

prop: =/= p

This gives a p-value = .934

(standard significance level is .05, so this p-value is much larger)

Which function describes the arithmetic sequence shown?

Shkiper50 [21]

Answer: C.) f(x) = -2x + 5

If you start from x=1, you will see the patter follows -2x + 5

-2(1) +5 = -2+5 = 3
-2(2)+ 5 = -4 + 5 = 1
-2(3) + 5= -6 +5 = -1
And so on...

Line m is drawn so that it is perpendicular to two distinct planes, Q and R. What must be true about planes Q and R?

UNO [17]

B. are parallel.

Line m is drawn so that it is perpendicular to two distinct planes, Q and R. Therefore, planes Q and R are parallel.

Since it doesn't state that two planes intersect with each other, it is safe to assume that only line m is their connection. The planes are parallel with each other.
