Answer:
Yes
Step-by-step explanation:
1/8-10(3/4-3/8x)+5/8x
1/8-(30/4-30/8x)+5/8x
1/8-30/4+30/8x+5/8x
Lcm is 8
1-60+30x+5x/8
-59+35x/8
Factorise
-1/8(59-35x)
So when comparing the two,they are observed to be the same
Of usually means multiply
1/3 x 3/7
=3/21
It’s cut off, but the bottom side of the triangle is labelled ‘x’
hope this helps!
Step-by-step explanation:
The plumber's daily earnings have a mean of $145 per day with a standard deviation of
$16.50.
We want to find the probability that the plumber earns between $135 and
$175 on a given day, if the daily earnings follow a normal distribution.
That is we want to find P(135 <X<175).
Let us convert to z-scores using

This means that:

We simplify to get:

From the standard n normal distribution table,
P(z<1.82)=0.9656
P(z<-0.61)=0.2709
To find the area between the two z-scores, we subtract to obtain:
P(-0.61<z<1.82)=0.9656-0.2709=0.6947
This means that:

The correct choice is C.
1st : Find the volume of the rectangular block:
12 × 10 × 20 = 2400 cm^3.
2nd : Find the volume of a cylinder

Where r is radius & h is height.
so:

= 76.02654222 cm^3
Lastly, divide the volume of the rectangular block by the volume of the cylinder
2400 ÷ 76.026 = 31.5679226
You can't round it up so the answer is F) 31
