Which improper fraction is represented by the shaded
area?

Answers

Answer:

C: 5/4

Step-by-step explanation:

What is an improper fraction? An improper fraction is when the numerator (top number) is greater than the denominator (bottom number).

How is it 5/4? In the diagram, there are 4 separations, or 4 equal parts in each box. This means the denominator will be 4.

There are 5 "fourths" or five sections in these four-part boxes. So, the answer is 5/4.

suppose f(×) = 2^×, sketch a graph of f(×) and f^-1(×)​

Answers

Let f(x) = y

y = 2^x

x = 2^y

Solve for y.

ln x = ln(2^y)

ln x = y ln 2

ln x/ln 2 = y

Replace y with f^(-1) x.

f^(-1) x = ln x/ln 2

We now know f(x) and f^(-1) x.

Answer:

<3 is 79 degrees and they are corresponding angles

Answer: The answer to the first question is measure 3 is 79 degrees. For the second one the angles are known as corresponding angles.

Step-by-step explanation:

Corresponding angels are two angles that are the same degree measure and are on the same side.

The measures of the angles in triangle UVW are shown in the diagram below:
A. 21
B. 39
C. 45
D. 126

Answers

Answer:

D. 126

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

30 + 24 + 3x - 9 = 180 add like terms

45 + 3x = 180 subtract 45 from both sides

3x = 135 divide both sides by 3

x = 45 and to find angle UVW replace x with 45

3*45 - 9 = 126

if each quadrilateral below is a square, find the missing measures.

please help :(

Answers

vu=15 su=square root 450 TV= square root 450 SW= squareroot 450/2

We want to find the missing measures for the given square.

VU = 15TV = 21.2SU = 21.2SW = 10.6

Working with squares.

We know that squares have the same length in all of their 4 sides, with that in mind we can see that:

TS = TU = UV = SV = 15

Then we can already complete:

VU = 15

Now we need the two diagonals, SU and TV.

The diagonal for a square of side length s is:

diagonal = (√2)s

Then the diagonals for our square are:

TV = SU = (√2)*15 = 21.2

And SW is half of the diagonal, so we have:

SW = 21.2/2 = 10.6

A box contains 16 chocolates, of which
3 are known to contain nuts.
Two chocolates are selected at random.
a. Find the probability that
a exactly one chocolate contains
nuts

b at least one chocolate contains
nuts.

Answers

Answer:

3/16??? and 1/16???

Step-by-step explanation:

im so sorry this might be wrong

The probability that a exactly one chocolate contains nuts is 3/16 and probability that at least one chocolate contains nuts is 0.339.

How to calculate probability ?

Probability is calculated by dividing the number of possible outcomes by the total number of possible outcomes. Probability and odds are two distinct concepts. Odds are calculated by dividing the probability of something happening by the probability of it not happening.

When you calculate probability, you are estimating the likelihood of something occurring and representing it with a precise number.

The probability that a exactly one chocolate contains nuts

No of total chocolates = 16 chocolates

No of chocolates contain nuts = 3

The probability that a exactly one chocolate contains nuts = 3/16

Probability that  at least one chocolate contains nuts is

P(at least one contains nut) = 1 – P(given contains no nuts )^n

P(at least one contains nut) = 1 – (0.8125)^2

P(at least one contains nut) = 0.339

Probability that  at least one chocolate contains nuts = 0.339

Determine the number of different ways to draw two cards of the same rank when
drawing two cards from a 60-card deck (assume that there are 4 cards in each rank).

Answers

Answer:

Step-by-step explanation:

The number of different ways to draw two cards of the same rank will be 1/195.

What is probability?

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

A 60-card deck (assume that there are 4 cards in each rank).

Then the total number of events is given as,

Total event = ⁶⁰C₂

Total event = 60! / [(60 - 2)! x 2!]

Total event = (60 x 59) / 2

Total event = 1,170

The number of the favorable event will be given as,

Favorable event = ⁴C₂

Favorable event = 4! / [(4 - 2)! x 2!]

Favorable event = (4 x 3) / 2

Favorable event = 6

Then the probability is given as,

P = 6 / 1,170

P = 1/195
