Answer:

one half the measure of their intercepted arcs.

m arc CDE= 2 ⋅ m∠CFE and arc CFE= 2. m∠CDE.

Step-by-step explanation:

Quadrilateral CDEF is inscribed in circle A, so m arc CDE + m arc CFE= 360°. ∠CFE and ∠CDE are inscribed angles, which means that their measures are 1/2 the measure of their intercepted arcs. So, m arc CDE= 2 ⋅ m∠CFE and arc CFE= 2. m∠CDE.

Answer:

113.1cm^2

Step-by-step explanation:

We know the area for a circle is pi * r^2, where r is the radius. We know the diameter, so all we need to do to find the radius is half the distance of the diameter, which would then be 6 cm. We plug in 6 as r, we get 36pi cm^2 as our exact answer. And a good approximation would be 113.1 cm^2.

Answer: 37.68

Step-by-step explanation:

First off our formulas are:

[tex]Area: A=\pi r^2\\Circumference: C=2\pi r[/tex]

Solve for r in the area formula.

[tex]A=\pi r^2\\r^2=\frac{A}{\pi} \\r=\sqrt[]{\frac{A}{\pi} }[/tex]

[tex]r=\sqrt[]{\frac{36\pi}{\pi} }[/tex]

[tex]r=\sqrt[]{36}[/tex]

r=6

Plug this into the circumference formula.

[tex]C=2\pi r\\C=2(3.14)(6)\\C=37.68[/tex]

3x + 5

Step-by-step explanation:

Add like terms together:

8x - 2 - 5x + 7

3x - 2 + 7

3x + 5

Answer:

smaller x: -4

larger x: 1

Step-by-step explanation:

We need to factor this. In order to do so, we need to find factor pairs of the coefficient of x^2 (which is 1 in this case) and of the constant (-4 in this case) such that they add up to 3.

Here, the factors of 1 are obviously just 1 and 1. The factors of -4 are (1, -4), (-1, 4), and (2, -2). Notice that 1 * 4 + 1 * (-1) = 3, so we know that our factor pair from 1 is (1, 1) and our factor pair from -4 is (-1, 4).

Then, we factor this quadratic into: (x - 1)(x + 4) = 0. Now, solve for x by setting each of these two factors equal to 0:

x - 1 = 0  ⇒  x = 1

AND

x + 4 = 0  ⇒  x = -4

So, the solutions are x = -4 and x = 1.

Hope this helps!

Answer:

smaller x= -4

larger x= 1

Step-by-step explanation:

x² + 3x - 4 = 0

x² + 4x - x - 4 = 0

x(x + 4) - (x + 4) = 0

(x - 1)(x + 4) = 0

x = -4, 1

There are a total of 11 numbers.

a) Mean = sum of the above / 11 = 268/11

= 24.4.

b) Median = the middle number = 24,

c) Mode The  numbers 24 and 39 occur twice so there are 2 modes.

Answer:

The answer is 2.0190

Step-by-step explanation:

From the given question,

We recall that,

p = 141/241 = 0.5850

so, p = 0.5

The Hypothesis is:

H₀ : P = 0.5, this means that  H0:50% of the games played will be won

vs

H₁ : P > 0.5, This indicates that, win is greater than 0.5 due to home field advantages.

n=241,x=141

Then,

SD(p)=√(p*q/n)=√(0.5*0.5/141)=0.0421

z = p - p/ SD (p) = 0.5850 - 0.5/0.0421 = 0.085/0.0421 =2.0190

therefore, there is strong evidence that there is home field advantages in professional football.

Following are the calculation to the hypothesis test:

[tex]\to \hat{p}= \frac{141}{241}=0.5850 \\\\\to p=0.5[/tex]

Hypothesis:

[tex]H_{0}:P=0.5[/tex] implies [tex]H_0:50\%[/tex] of a games would be won.

vs

[tex]H_{1}:P>0.5[/tex] because of home-field advantages, the victory exceeds  [tex]0.5[/tex] . [tex]\to n=241 \\\\\to x=141\\\\\to SD(p)=\sqrt{(\frac{p\times q}{n})}=\sqrt{(\frac{0.5\times 0.5}{241})}=\sqrt{(\frac{0.25}{241})}= \sqrt{0.001}=0.0322 \\\\\to z=\frac{\hat{p}-p}{SD(p))}=\frac{0.5850-0.5}{0.0322}=\frac{0.085}{0.0322}=1.624\\\\ \to P(Z>1.624)=0.0521879[/tex]

conclusion [tex]P-value =0.0521879<0.05[/tex], As a result, we reject the null hypothesis, i.e. there's really significant evidence that home-field advantage exists in pro football.

Answer:

10/25, 4/10, 20/50

Step-by-step explanation:

They all simplify to be 2/5.

The mean absolute deviation of the group of SAT scores is approximately 169.8.

To find the mean absolute deviation (MAD) of the group of SAT scores, we follow these steps:

1. Calculate the mean (average) of the scores.

2. Find the absolute deviation of each score from the mean.

3. Calculate the mean of these absolute deviations.

Let's proceed with the calculations:

1. Calculate the mean:

[tex]\[ \text{Mean} = \frac{1510 + 1480 + 2100 + 1800 + 1300 + 1250 + 1400 + 1430 + 1390 + 1520}{10} \][/tex]

[tex]\[ \text{Mean} = \frac{14,580}{10} \][/tex]

[tex]\[ \text{Mean} = 1458 \][/tex]

2. Find the absolute deviation of each score from the mean:

[tex]\[ \text{Absolute deviations: } |1510 - 1458| = 52, |1480 - 1458| = 22, |2100 - 1458| = 642, |1800 - 1458| = 342, \][/tex]

[tex]\[ |1300 - 1458| = 158, |1250 - 1458| = 208, |1400 - 1458| = 58, |1430 - 1458| = 28, |1390 - 1458| = 68, |1520 - 1458| = 62 \][/tex]

3. Calculate the mean of these absolute deviations:

[tex]\[ \text{MAD} = \frac{52 + 22 + 642 + 342 + 158 + 208 + 58 + 28 + 68 + 62}{10} \][/tex]

[tex]\[ \text{MAD} = \frac{1698}{10} \][/tex]

[tex]\[ \text{MAD} = 169.8 \][/tex]

Therefore, the mean absolute deviation of the group of SAT scores is 169.8 (rounded to the nearest tenth).

The mean absolute deviation of the group of SAT scores is 162 (rounded to the nearest tenth).

To find the mean absolute deviation (MAD) of a set of data, you first need to calculate the mean (average) of the data, then find the absolute difference between each data point and the mean, and finally, calculate the average of these absolute differences.

Calculate the mean of the given SAT scores: (1510 + 1480 + 2100 + 1800 + 1300 + 1250 + 1400 + 1430 + 1390 + 1520) / 10 = 14660/10

= 1466

Calculate the absolute deviation of each score from the mean: |1510 - 1466|, |1480 - 1466|, and so on.

This gives - 44+14+634+334+166+216+66+36+76+54

= 1620

Calculating MAD -

= 1620/10

= 162

The mean absolute deviation of the group of SAT scores is 162 (rounded to the nearest tenth).

Answer:

420 feet

Step-by-step explanation:

GIVEN: The High Roller wheel in Las Vegas has a diameter of [tex]520[/tex] feet and its base is [tex]30[/tex] feet off the ground. You board a gondola on the wheel and rotate [tex]240[/tex] degrees counterclockwise before the wheel temporarily stops.

TO FIND: How high above the ground are you when the wheel stops?

SOLUTION:

Consider the figure attached.

As wheel rotate counter clockwise [tex]240^{\circ}[/tex], its current position is [tex]120^{\circ}[/tex] clock wise.

Total height [tex]=260+30+h\rightarrow290+h[/tex]

Calculating value of [tex]h[/tex]

[tex]\sin 30^{\circ}=\frac{h}{260}\impliesh=260\sin30^{\circ}[/tex]

[tex]\implies h=260\times\frac{1}{2}=130feet[/tex]

Total height [tex]=290+130[/tex] feet

                    [tex]=420\text{ feet}[/tex]

Hence total height is 420 feet

Answer:

The area of the circular ripple after t second is

A =25π t²

where A is in cm².

Step-by-step explanation:

Given that,

Circular ripple that travels outward at a speed of 5 cm per second.

It means that, the radius of the circular ripple increases at a seed 5 cm/ s.

Therefore the radius of the circular ripple after t seconds is

r(t)= 5t

where r(t) is in cm.

We know ,

The area of a circular object is = π r²

The area of the circular ripple after t second is

A= π(5t)²

 =25πt²

where A is in cm².

The area, A. of the circle in terms of the number of seconds, t, that have passed since the ball hits the lake is A(t)= 25t²π

The formula for calculating the area of the circular ripple as a function of time is expressed as:

A(t) = πr(t)²

Given that the ripple travels outward at a speed of 5 cm per second, hence;

r(t) = 5tcm/s

Substitute the radius into the formula to have:

A(t) = π(5t)²

A(t)= 25t²π

Hence the area, A. of the circle in terms of the number of seconds, t, that have passed since the ball hits the lake is A(t)= 25t²π

Answer: A which is x=-3

Step-by-step explanation:

You put 2x to the left hand side which makes it a negative. Then you move the 5 to the other side since 2x has a variable and 5 doesn't. You need to put one side of the equation with a variable and one not. Then 5 becomes -5 because you move it over. So it will be 6x-2x= - 7- 5.Then subtract 6x and 2x which is 4x. -7 subtract -5 equals -12. Divide -12 and 4 which makes it -x=3.
