48/3= 16 (cups)
16+16= 32 (twice as many plates)
So it would be 16

$8+292=300$

8 out of 300 were defective.

$\frac{8}{300}=\frac{x}{3000} \\ \\ 8*3000=300*x \\ \\ 24000=300x \\ \\ 80=x$

80 pairs were defective

A ferry will safely accommodate 68 tons of passenger cars. Assume that the mean weight of a passenger car is 1.8 tons with stand

nika2105 [10]

Answer:

$P (Z$

Step-by-step explanation:

We want the probability that the 35 cars are loaded onto the ferry. Therefore:

Since

μ=1.8 and σ=0.5 we have:

P(X<35 )=P ( X−μ<35−1.8 )=P((X−μ)/σ<(35−1.8)/0.5)

Since

(x−μ)/σ=Z and

$(35-1.8)/0.5=66.4$

we have:

$P (X$

Use the standard normal table to conclude that:

$P (Z$

The coordinates of parallelogram PVWZ are P(0, 0), V(-p, q), and W(-p - r, q). Find the coordinates of Z without using any new v

Drupady [299]

For the answer to the question above asking to f<span>ind the coordinates of Z without using any new variables.
</span>

Vector WZ equals vector VP, which is (p, -q)
So Z is (-p - r + p, q - q) which is (-r, 0)
I hope my answer helped you.

The minimum distance from Earth to the Sun is 91.4 million miles. The maximum distance is 94.5 million miles write a absolute va

d1i1m1o1n [39]

Solution :

The minimum distance from Earth to the Sun is 91.4 million miles

The maximum distance is 94.5 million miles

$d_{min} = 91.4, d_{max} = 94.5$

$d=\frac{d_{min} + d_{max}}{2}$

$d=\frac{91.4 + 94.5}{2}$

d=92.95

$d_{sol}=\frac{d_{max} - d_{min}}{2}$

$d_{sol}=\frac{94.5 - 91.4}{2}$

$d_{sol} =1.55$

Absolute Value Equation:

|x - d| = $d_{sol}$

|x - 92.95| = 1.55

Brock is training for a Crossfit competition. He began the training completing pull-ups and box jumps origanally, his training p

siniylev [52]

If the adjusted ratio was 2:7, then

2x is the number of pull-ups

and

7x is the number of box jumps.

You can state that since he completed 63 box jumps at the end of his training, then

7x=63,

x=9

and

2x=18.

The total number of exercises performed is 2x+9x=18+63=81.

As at start the ratio was 5:4, then

5y was the number of pull-ups

and

4y was the number of box jumps.

Therefore, 5y+4y=81,

9y=81,

y=9

and 5y=45, 4y=36.

Answer: Initially: 45 pull-ups and 36 box jumps. At the end: 18 pull-ups and 63 box jumps.
