Answer:

m<Y = 68°

Step-by-step explanation:

A tangent drawn to a circle makes a 90° angle with the radius that intersects it at the point of tangency. That means that m<X = 90°.

The sum of the measures of the angles of a triangle is 180°.

m<X + m<Y + m<Z = 180

90 + m<Y + 22 = 180

m<Y + 112 = 180

m<Y = 180 - 112

m<Y = 68

Order 0.709, 0.710, 0.79, and 0.079 from smallest to largest.

TEA [102]

0.079, 0.709, 0.710, 0.79

You will have to look at the placement of each digit.

In this case, after the decimal point:
tenths is the largest (the number directly to the right of the decimal point)
hundredths is next (the number directly to the right of the tenths place)
thousands is the smallest (in this case, next to the hundreds place)

hope this helps

第 5 个问题 a multiple choice exam has 10 questions. each question has 3 possible answers, of which one is correct. a student knows

tatuchka [14]

The chances that the student was merely guessing is 1/3.

Bayes Theorem determines the conditional probability of an event A given that event B has already occurred.

denoted by

$P(A/B)=\frac{P(A)*P(B/A)}{P(B)}$

let A be the event that the student knows the answer .

B be the event that the student does not knows the answer .

and

E be the event he gets answer correct .

According to the given question

$P(A)=\frac{4}{10} \\\\ P(B)=1-\frac{4}{10} =\frac{6}{10}$

Probability that the answer is correct ,given that he knows the answer is

$P(E/A)=1$

Probability that the answer is correct ,given that he guesses it is

$P(E/B)=\frac{1}{3}$ [as the MCQ has 3 options and only one is correct]

We need to find the probability that he guesses the answer given that it is correct.

Required probability $P(B/E)=\frac{P(B)*P(E/B)}{P(A)*P(E/A)+P(B)*P(E/B)}$

Substituting the values we get

$P(B/E)=\frac{\frac{6}{10} *\frac{1}{3} }{\frac{4}{10} *1+\frac{6}{10} *\frac{1}{3} }$

$=\frac{6}{30}*\frac{30}{18} \\ \\ =\frac{6}{18} \\ \\ =\frac{1}{3}$

Therefore , the chances that the student was merely guessing is 1/3.

FIND THE MISSING DIMENSION! NEED ASAP! TINY SQUARE IS A =3025 in ²

Nata [24]

Answer:

Step-by-step explanation:

Rule: never completely trust a diagram that comes with a geometry question. This is a case in point. The "tiny" square is actually much larger than the "larger" square.

If you are trying to find the length of the sides of the squares, the formula is

Area = side^2

3025 = side^2

Take the square root of both sides.

sqrt(3025) = sqrt(side^2)

To find the square root of 3025, do the following

Press √

type in 3025

type in =

You should get 55.

======================

The second square is done the same way

√

90.75

And you should get 9.526
