4 0

Answer:

Step-by-step explanation:

4 and 8 are corresponding angles as they form at parallel lines cut by a transversal.

4 and 3 are supplementary angles (they both add up to 180°).

4 and 1 are vertically opposite angles and are equal to each other.

From the above explanations, only 4 and 8 are corresponding angles.

I hope this helps! I would really appreciate it if you would please mark me brainliest! Have a blessed day!

The distance between City A and City B is 500 miles. A length of 1.8 feet represents this distance on a certain wall map. City C

Ratling [72]

Answer: 800 miles

Step-by-step explanation:

Let the actual distance between City C and City D be represented by x.

The information given in the question can be formed into an equation as:

1.8 feet / 2.88 feet = 500 miles / x

Cross multiply

1.8 × x = 500 × 2.88

1.8x = 1440

x = 1440/1.8

x = 800

Therefore, the actual distance between City C and City D is 800 miles.

The mean number of daily surgeries at a local hospital is 6.2. Assume that surgeries are random, independent events. (a) The cou

Scilla [17]

Answer:

a) correct option is

Poisson distribution is 6.2 and standard deviation is 2.49

b) probability for only 2 or less than 2 surgeries in a given day is 0.0536

Step-by-step explanation:

Given data:

mean number is given as 6.2

correct option is

Poisson distribution is 6.2 and standard deviation is 2.49

we know that variance is given as $\sigma^2 = mean = 6.2$

hence, standard deviation is given as $\sqrt{6.2} = 2.48998$

thus standard deviation is 2.49

correct option is

Poisson distribution is 6.2 and standard deviation is 2.49

b) probability for only 2 or less than 2 surgeries in a given day is

$P(X \leq 2) = P(X =0) + P(X =1) + P(X =2)$

$= \frac{e^{-6.2} 6.2^0}{0!} +\frac{e^{-6.2} 6.2^1}{1!} +\frac{e^{-6.2} 6.2^2}{2!}$

= 0.002029 + 0.012582+ 0.039006

= 0.053617

= 0.0536

The opposite sides of a parallelogram have measures (2x+10) cin and (x+15)

xz_007 [3.2K]

Answer:

The measure of the sides is 20 cm.

Step-by-step explanation:

Opposite side of a parallelogram:

Opposite sides of a parallelogram are congruent, that is, they have the same measure.

Measures (2x+10) cm and (x+15) cm:

This means that:

$2x + 10 = x + 15$

$2x - x = 15 - 10$

$x = 5$

2x + 10 = 2*5 + 10 = 10 + 10 = 20

The measure of the sides is 20 cm.

What is 3 1/3 -1 1/2 as a fraction?

eduard

Answer:

11/6

Step-by-step explanation:

Step 1: Convert to Improper fractions

3 1/3 = 3*3/3 + 1/3 = 9/3 + 1/3 = 10/3

1 1/2 = 1*2/2 + 1/2 = 2/2 + 1/2 = 3/2

Step 2: Make common denominators

10/3 * 2/2 = 20/6

3/2 * 3/3 = 9/6

Step 3: Subtract

20/6 - 9/6

11/6

Answer: 11/6
