What is the value of x in the equation 2.5 (6x - 4) = 10 + 4 (1.5 + 0.5x)

Answer:

x = 2

Step-by-step explanation:

Given

2.5(6x-4) = 10 + 4 (1.5+0.5x)

First of all we will have to solve the parenthesis

(2.5)(6x)-(2.5)(4) = 10 + (4)(1.5)+(4)(0.5x)

15x-10 = 10+6+2x

We have to isolate x so that we can find its value

15x-10 = 16+2x

15x = 16+2x+10

15x-2x = 26

13x = 26

13x/13 = 26/13

x = 2 ..

Assume a random sample of size n is from a normal population. Assume a single sample t test is used to for hypothesis testing. T
valentinak56 [21]

Answer:

True

Step-by-step explanation:

Type I and Type II are not independent of each other - as one increases, the other decreases.

However, increases in N cause both to decrease, since sampling error is reduced.

A small sample size might lead to frequent Type II errors, i.e. it could be that your (alternative) hypotheses are right, but because your sample is so small, you fail to reject the null even though you should.

Answer:

Circumference of Circle B=19.625cm

Step-by-step explanation:

The circumference formula is: 2pie(r) = pie(d)

We have diameter of the first circle which is 6. Now, because the diameter of second circle is 25% greater than this,

Hence, we add 25% in 6:

6+25/100 =6+0.25=6.25 cm

Therefore, we have diameter of 6.25 for circle B.

Now, we need to find the circumference of the Circle A.

circumference= pie(d) = pie(6)= 3.14times6= 18.84

Now use the proportional reasoning to find Circumference of Circle B:

circumference of Circle A/diameter Circle A = circumference of Circle B/diameter Circle B

18.84/6=circumference of Circle B/6.25

Cross multiply and divide:

(18.84times6.25)/6 = Circumference of Circle B

Solve:

Circumference of Circle B=19.625cm

Hope this helps!

Four notebooks 4.40. how many notebooks can you buy for 6.60.
denis23 [38]
We know we have $4.40 for 4. Divide 4.40 by 4, you get 1.10. So it's $1.10 per notebook. Therefore, divide 6.60 by 1.10. You get 6, so you can get six notebooks with $6.60.
Hope this helps!
