Total length of stick = 42 inches.

Let the shorter piece be x inches.

Thus, the longer piece is 2x.

2x + x = 42

3x = 42

x = 14

Therefore, the length of the two pieces are 14 inches and 28 inches.

What is the magnitude (size) of 6.8?
lidiya [134]

Answer:

C. 6.8, because |6.8|= 6.8

Step-by-step explanation:

The magnitude of a directed number is a property that turns the number to a positive of its value. Thus, the magnitude of a negative number equals its positive value. Examples:

Find the magnitude of the following numbers:

i. -20

ii. 10

iii. -5

iv. 2

The magnitudes of the numbers can be expressed as:

i. |-20| = 20

ii. |10| = 10

iii. |-5| = 5

iv. |2| = 2

Therefore, the magnitude of 6.8 = 6.8, because |6.8|= 6.8.

Find the common differece of the sequence: 2,9,16,23
riadik2000 [5.3K]
So if 2 is the first term then if n=1 then n+1=sequence so far but

second term is 9 so if n=2 then the 2nd term=9
you must use trial and error to find
so it is
7n-5 so if n=1 then
7(1)-5=7-5=2

if n=2 then
7(2)-5=14-5=9
sucess

the equation is 7n-5

A local charity believes they receive more money from people in the Chevy Chase area than from people in the Alexandria area of
kaheart [24]

Answer: The critical value of the test is 2.807.

Step-by-step explanation:

Since we have given that

n = 24

So, the degree of freedom v = n-1 = 24 - 1=23

Since, n>30, so we will use 't-test'.

Here, α = 0.01

so, According to t-table, we get that

t_{\alpha ,v}=t_{0.01,23}=2.807

If we take α, then we are taking about two tail test.

If we take \dfrac{\alpha }{2} then we are talking about one tail test.

But in both the cases, the result will be same.

Hence, the critical value of the test is 2.807.
