Answer:

The muscular work completed by four men will be 2400 ft. lbs.

Step-by-step explanation:

See the diagram of the ramp.

Four men carry 20 boxes each up a ramp as shown.

So, 4 men carry total (4 × 20) = 80 boxes up the ramp and each box weighs 5 pounds.

Then, the 4 men carry total (80 × 5) = 400 lb weight up the ramp.

Now, the vertical height of the ramp from the ground level is 6 ft.

Hence, the muscular work completed by four men will be (400 × 6) = 2400 ft. lbs. (Answer)

Answer:

The requirements that are necessary for a normal probability distribution to be a standard normal probability distribution are <em>µ</em> = 0 and <em>σ</em> = 1.

Step-by-step explanation:

A normal-distribution is an accurate symmetric-distribution of experimental data-values.  

If we create a histogram on data-values that are normally distributed, the figure of columns form a symmetrical bell shape.  

If X \sim N (µ, σ²), then Z=\frac{X-\mu}{\sigma}, is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z \sim N (0, 1).

The distribution of these z-variates is known as the standard normal distribution.

Thus, the requirements that are necessary for a normal probability distribution to be a standard normal probability distribution are <em>µ</em> = 0 and <em>σ</em> = 1.

Find the sum of the following geometric sequences. d) 3 terms a= 16 r=3/4​
kodGreya [7K]

Answer:

S₃ = 37

Step-by-step explanation:

given a₁ = 16 and r = \frac{3}{4} , then

a₂ = a₁ × \frac{3}{4} = 16 × \frac{3}{4} = 12

a₃ = a₂ × \frac{3}{4} = 12 × \frac{3}{4} = 9

then

S₃ = a₁ + a₂ + a₃ = 16 + 12 + 9 = 37

Someone please help me with angle relationships in circles with algebra.
Mrac [35]
If angle TSV=6x+17 then arc it intercept (SV)would be double it

6x+17=1/2 (15x+13)
12x+34=15x+13
21=3x
x=7

Arc SV=15(7)+13
=118

And angle TSV=6(7)+17
=59

There are 360 degrees in a circle and the measure of the arc would be equal to the central point so the sum of all the arcs equals 360

Arc SV+ arc SUV=360
118+SUV=360
Arc SUV=242
