Find the volume of the rectangular prism (Please help fast!)

Mathematics

Answer:

Vol = 294 cubic ft

Step-by-step explanation:

Vol = l × w × h

But l × w is the area of the base. So another formula for volume is:

Volume =

Base area × height

V = Bh

This also works for any prism(any shaped base), cubes, and cylinders.

Here, V = 42×7

V = 294 ft^3

Answer:

6

Step-by-step explanation:

so this is (base times hight)

(bH)

42=7x

you didvide 7 from both sides

42 divided by 7 is 6

so basically its 6

because that would be your base thats what you are missing

then its just baseically (BH) (7 times 6)= 42

if this is wrong im so sorry I just learned this good luck

X + 20 = 5

Subtract 20 from both sides:

X = -15

A set of average city temperatures in May are normally distributed with a mean of 20.66 ^\circ \text{C}20.66
Angelina_Jolie [31]

Answer:

0.9962

Step-by-step explanation:

The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

z=\frac{x-\mu}{\sigma}\\ \\\mu=mean,\sigma=standard\ deviation, x=raw\ score

μ = 20.66°C, σ = 2°C

For x < Singapore temperature, i.e. x < 26

z=\frac{x-\mu}{\sigma} =\frac{26-20.66}{2}=2.67

From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962
