Find the area of the figure.

seraphim [82]

$\huge \bf༆ Answer ༄$

At first Divide the figure into two rectangles, I and Il

Area of figure l is ~

$\sf24 \times (40 - 30)$

$\sf24 \times 10$

$\sf240 \: \: ft {}^{2}$

Area of figure ll is ~

$\sf 18 \times 30$

$\sf540 \: ft{}^{2}$

Area of whole figure = Area ( l + ll )

that is equal to ~

$\sf240 + 540$

$\sf780 \: \: ft{}^{2}$

How do I Graph y= –73x+2 .

Romashka-Z-Leto [24]

Answer:

See attachment

Step-by-step explanation:

You can obtain any two points on the graph of $y=-73x+2$ and use it to draw its graph.

When x=0, $y=-73*0+2=2$

So you plot (0,2)

When x=1, $y=-73*1+2=-71$

You again plot (1,-71).

With a straight edge you can now draw a straight line through the two points.

Let z denote a random variable that has a standard normal distribution. Determine each of the probabilities below. (Round all an

Lorico [155]

Answer:

P(Z < 2.37) = 0.9911.

Step-by-step explanation:

We are given that Let z denote a random variable that has a standard normal distribution.

Let Z = a random variable

So, Z ~ Standard Normal(0, 1)

As we know that the standard normal distribution has a mean of 0 and variance equal to 1.

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1)

where, $\mu$ = mean = 0

$\sigma$ = standard deviation = 1

Now, the probability that z has a value less than 2.37 is given by = P(Z < 2.37)

P(Z < 2.37) = P(Z < $\frac{2.37-0}{1}$ ) = P(Z < 2.37) = 0.9911

The above probability is calculated by looking at the value of x = 2.37 in the z table which has an area of 0.9911.

The top of a table is a parallelogram with a base of 28 cm and a height of 20 cm. Patty wants to cover the table with tiles that

suter [353]

The area of the top of the table is 28 × 20 = 560 cm2. The area of Patty’s tiles is 8 cm2 each and the area of Jake’s tiles is 9 cm2 each. Patty will need 560 ÷ 8, or 70, tiles. Jake will need 560 ÷ 9, or about 63, tiles. So, Patty will use about 7 more tiles.
