Answer:

D. 79%

Step-by-step explanation:

Took the the on USA Test prep

If a point is randomly selected from the rectangular area of the graph, the probability that it will be in the blue region is 79%.

The ratio of the number of favorable outcomes to the total number of outcomes of an event is known as probability.

It is given that, the length=20, the width=10, and the radius of half circle=10.

Calculate the area of the rectangle.

Knows the area of the rectangle is the product of length and width.

So,

[tex]\Rightarrow \text{Area of rectangle}=\text{10}\times \text{20} \\ \Rightarrow \text{Area of rectangle}=200 \\[/tex]

Calculate the area of the half-circle.

Knows the area of the half-circle[tex]=\frac{\pi r^{2} }{2}[/tex].

So,

[tex]& \Rightarrow \text{Area of half circle}=\frac{3.14\times 10\times 10}{2} \\ & \Rightarrow \text{Area of half circle}=\frac{314}{2} \\ & \Rightarrow \text{Area of half circle}=157 \\[/tex]

Calculate the probability that it will be in the blue region.

Knows the formula for the probability, [tex]\text{Probability}\left( \text{Event} \right)=\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}[/tex]

So,

[tex]& \Rightarrow \text{Probability}=\frac{\text{157}}{200} \\ & \Rightarrow \text{Probability}=0.78539 \\ & \therefore \text{Probability }\%=79\% \\[/tex]

Thus, the correct answer is an option (D). i.e., 79%.

Answer:

The region of acceptance gets bigger and the null hypothesis is mostly accepted as it lies in the acceptance region.

Step-by-step explanation:

As the level of significance is decreased the area for the favorable outcomes is increased. The value of ∝= 0.1 has a narrower area of favorable outcomes then the values of ∝= 0.05 or 0.01 because the value 0.1 ( 1%) is closer to the middle value or at the extreme values of the distribution as the case may be for 2 tailed or 1 tailed test.

Significance level        Two tailed Test          One tailed test

0.1                                   ± 1.645                               ±1.28

0.05                                 ±1.96                                ± 1.645

0.01                                ± 2.58                                 ±  2.33

So if the middle point is taken as zero we see that the spread of the area of the favorable values increases as the value of ∝ significance level decreases.

The region of acceptance gets bigger and the null hypothesis is mostly accepted as it lies in the acceptance region.

Answer:

24°c

Step-by-step explanation:

Cuando se dice que la temperatura esta "mayor" significaria que esta aumentando y entorno subiendo a ser mas caliente. Siendo este el caso, si la temperatura a las 3:00 estaba a 12c bajo cero entonces a las 7:00 estaria a 24c. Esto es por que un aumento de tres vecesseria un aumento de 36 grados (12*3). 12c grados bajo cero seria un numero negativo y si sumamos estos numeros nos daria 24c grados.

-12 + 36 = 24

x=42

Step-by-step explanation:

2(x-8)=68

Distribute the 2

2x-16=68

Use the addition property of equality (add 16 to both sides)

2x=68+16

2x=84

Use the division property of equality (divide both sides by 2)

x=84/2

x=42

Answer:

Sample A Estimate: 330

Sample B Estimate: 420

Sample C Estimate: 360

Median: 360

Range: 90

Step-by-step explanation:

For the sample estimate, multiply 600 by 11/20, 7/10, and 3/5 in order.

600 * 11/20

6600/20

330 people for Estimate A.

600 * 7/10

420/10

420 people for Estimate B.

600 * 3/5

1800/5

360 people for Estimate C.

330, 360, 420

360 is the median of these estimates.

420 - 330 = 90

90 is the range of these estimates.

The sum of the 48 terms will be $2,496. Then the correct option is A.

Let a₁ be the first term, n the number of the terms, and l be the last term of the sequence.

Then the sum of all the terms will be given as,

S = [n (a₁ + l )] / 2

Let a₁ be the first term and d is the common difference between the terms. Then the nth term will be given as

[tex]\rm a_n = a_1 + (n - 1)d[/tex]

Beginning with Rodney’s first month of high school, his father deposits $5 into Rodney’s savings account.

Each month after the first month, his father deposits $2 more than the previous month.

Then the first term is $5 and the common difference is $2.

The total amount deposited in Rodney’s account after four years can be represented using the expression.

Then the total number of the terms will be

n = 4 x 12

n = 48 months

Then the 48th term of the sequence will be

a₄₈ = 5 + (48 – 1) · 2

a₄₈ = 5 + 47 · 2

a₄₈ = 5 + 94

a₄₈ = 99

Then the sum of the 48 terms will be

S = 48 (5 + 99) / 2

S = 24 × 104

S = $2,496

Then the correct option is A.

3. The origin is the point where the X and Y axis meet; (0,0); by the 0

4. The points will be written as A, B, C. This is going from left to right. So the first box on the coordinate plane furthest to the left with be labeled with A. Then the second box furthest from the left; the middle box; will be labeled with B. Then the last box will be labeled C

5. (4,6)

6. (2,9)

7. (0,4)

8. When Allie identified the point, she mixed the X and Y coordinates. To identify a point you first want to find the point following the X axis. Then do the same with the Y axis. After doing this you should have 2 numbers, in which are 3 and 7. Now when writing the coordinates, the X axis ALWAYS comes first. So it should look like (7,3)

Step-by-step explanation:

area circle = πr²   or  π(d/2)²  but how to find the diameter?

The only angles I can see to calculate is in the small right triangle

The smaller angle on the right is ...

        sin Ф = opp/hyp = 6/10    Ф = 36.87°

This angle is the same as the small angle on the LARGE right triangle

So now I want to calculate the side (diameter) opposite the smaller angle

      sin Ф = opp/hyp = diameter/300 = sin 36.87°    

                  diameter = 300 sin 36.87°

                                  = 300 (6/10)

                                  = 180 ft

area circle = πr²   or  π(d/2)²

area circle =  π(180/2)²

area circle = 25446 ft²  which is close to answer A  25434 ft²

There is actual no need to find the sin Ф wasted step      

just use 6/10  small triangle     is similar to diameter/300   the large triangle

  opp / hyp small  6/10  = diameter/300    diameter = 180

  area circle =  π(180/2)²  = 25446

[tex] \boxed{x = 45°} [/tex]

Step-by-step explanation:

When two chords intersect at a point in a circle, they form arcs, along with angles at the intersection point.

To determine the angle of the arc, we must apply this geometric rule:

[tex] Angle \: formed \: by \: chords = \frac{1}{2}(sum \: of \: intersecting \: arcs) [/tex].

Since we are looking for one of the arcs, we can rearrange this formula to solve for the first arc.

[tex] Angle \: formed \: by \: chords = \frac{1}{2}(sum \: of \: intersecting \: arcs) [/tex] →

[tex] Angle \: formed \: by \: chords = \frac{1}{2}(\overset{\frown}{BA} + \overset{\frown}{CD}) [/tex] →

[tex] 2 × Angle \: formed \: by \: chords = \overset{\frown}{BA} + \overset{\frown}{CD} [/tex] →

[tex] 2 × Angle \: formed \: by \: chords \: – \: \overset{\frown}{CD} = \overset{\frown}{BA} [/tex]

[tex] \overset{\frown}{BA} = 2 × Angle \: formed \: by \: chords \: – \: \overset{\frown}{CD} [/tex]

[Given]

[tex] \overset{\frown}{BA} = x° [/tex]

[tex] \overset{\frown}{CD} = 99° [/tex]

[tex] Angle \: formed \: by \: chords \: = 72° [/tex]

→

[tex] \overset{\frown}{BA} = 2 × Angle \: formed \: by \: chords \: – \: \overset{\frown}{CD} [/tex]

→

[tex] x° = 2 × 72° \: – \: 99° [/tex]

[tex] x° = (2 × 72°) \: – \: 99° [/tex]

[tex] x° = 144° \: – \: 99° [/tex]

[tex] \boxed{x° = 45°} [/tex]
