∠C and ∠D are vertical angles with m∠C=−3x+58 and m∠D=x−2 .<br><br><br><br> What is m∠D ?

11111nata11111 [884]

Vertical angles are equal

-3x + 58 = x - 2
-3x - x = -2 - 58
-4x = - 60
x = -60/-4
x = 15

m < D = x - 2....15 - 2 = 13 <====
m < C = -3x + 58....-3(15) + 58 = 13

In a certain college, 33% of the physics majors belong to ethnic minorities. Of 8 students are selected at random from the physi

Answer: 0.0187

Step-by-step explanation:

The binomial distribution formula for probability :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of getting success in x trials , n is the total number of trials and p is the probability of getting success in each trial.

Given : The probability that the physics majors belong to ethnic minorities =0.33

Number of students selected : n= 8

Now, the probability that more than 5 belong to an ethnic minority :-

$P(x>5)=P(6)+P(7)+P(8)\\\\=^8C_6(0.33)^6(0.67)^{2}+^8C_7(0.33)^7(0.67)^{1}+^8C_8(0.33)^8(0.67)^{0}\\\\=(\dfrac{8!}{6!2!})(0.33)^6(0.67)^{2}+(8)(0.33)^7(0.67)^{1}+(0.33)^8(0.67)^{0}\\\\=0.0186577086013\approx0.0187$

Hence, the probability that more than 5 belong to an ethnic minority = 0.0187

How many dimensions does a point in space have

Andreas93 [3]

Hello, hope you are having a wonderful day.

A point has 0 dimensions. It has no length, width, or depth.

So any point in space has 0 dimensions.

Now, a line has 1 dimension.

Rectangles, squares and other shapes have 2 dimensions.

Cylinders, cubes, cones and other figures have 3 dimensions.

Hope it helps. Please mark Brainliest; I really need it.

~An emotional teen who helps others with joy

Good luck.
