Answer:

332.5º

Step-by-step explanation:

To convert radians to degrees, you multiply the radians by 180/π.

133π/72 • 180/π

We can see that the π's will cancel out. Therefore, we have:

133/72 • 180

Multiply.

133/72 • 180 = 23940/72

Simplify.

665/2 = 332.5

Your answer is:

332.5º

Hope this helps!

Answer:

Step-by-step explanation:

Two consecutive numbers be 2x , (2x + 2)

(2x)(2x + 2) = 360

2x*2x + 2x *2 = 360

4x² + 4x = 360 {divide the equation by 4}

x² + x = 90

x² + x - 90 = 0

x² + 10x - 9x - 9*10 = 0

x(x + 10) - 9(x + 10) = 0

(x + 10)(x -9) = 0

x + 10 = 0

x = -10

2x = 2*(-10) = -20

2x + 2 = -20 + 2 = 18

(-20 , -18)

Answer:

4

Step-by-step explanation:

Simplify the given expression by doing each operation as per the order of operations. The order of operations is a systematic way of tackling an equation, that ensures that the result attained will be true when one solves the equation; remember, the order of operations states;

1. Parenthesis

2. Exponents

3. Multiplication/ Division

4. Addition/ Subtraction

Simplify the equation by combining terms as per the order of operations;

[ ( 4 + 8 ) * 3 ] / 9

= [ 12 * 3 ] / 9

= 36 / 9

= 4

Answer:

30 inches

Step-by-step explanation:

we can use the pythagorean theorem where the legs are 24 and 18 and the hypotenuse is the diagonal

24² + 18² = c²

576 + 324 = c²

900 = c²

c = [tex]\sqrt{900}[/tex] which equals 30

Given:

The piece-wise function is:

[tex]F(x)=\begin{cases}4&\text{ if }0\leq x<2\\3&\text{ if }2\leq x<4\\2&\text{ if }4\leq x<6\end{cases}[/tex]

To find:

The domain of the given function.

Solution:

Domain of the a function is the set of those values for which the function is defined. In other words, the set of input values is called domain.

The given function is defined for the intervals [tex]0\leq x<2,2\leq x<4,4\leq <6[/tex]. So, the domain of the given function is

[tex]Domain=\{x|0\leq x<2,2\leq x<4,4\leq <6\}[/tex]

Therefore, the correct option is B.

Answer:

[tex]5\sqrt{82}[/tex] units

[tex]\sqrt{84910}[/tex] units

Step-by-step explanation:

According to Pythagoras theorem, square of hypotenuse is equal to sum of squares of other two sides.

Consider the first figure:

Let [tex]x[/tex] denotes length of the third side.

[tex]23^2+39^2=x^2\\529+1521=x^2\\2050=x^2[/tex]

[tex]x=5\sqrt{82}[/tex] units

Consider the second figure:

Let [tex]y[/tex] denotes length of the third side.

[tex]87^2+96^2=y^2\\7569+9216=y^2\\84910=y^2\\[/tex]

[tex]y=\sqrt{84910}[/tex] units

Answer:

The 95% confidence interval for the true average strain is between 23.94% and 28.06%.

Step-by-step explanation:

We have the standard deviation of the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 13 - 1 = 12

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 12 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.18

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.18\frac{3.4}{\sqrt{13}} = 2.06[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 26 - 2.06 = 23.94

The upper end of the interval is the sample mean added to M. So it is 26 + 2.06 = 28.06

The 95% confidence interval for the true average strain is between 23.94% and 28.06%.

Complete options are;

A) Paired t-test for means

B) Paired Z-test for means

C) Z-test for proportion

D) t-test for means

E) Z-test for means

F) t-test for proportion

Answer:

B) Paired Z-test for means

Step-by-step explanation:

We are told that the distances travelled are normally distributed.

We are also trying to find out if the average distance travelled by the Titleist Pro V1 golf balls is farther than that of the Callaway Chrome Soft golf balls.

Also, the standard deviation of both cases are known.

Thus, this is where Paired Z-test for means is used.

According to the desired test, the correct option is:

a. paired t-test for means

At the null hypothesis, it is tested that ball 1 does not travel farther than ball 2, that is, the subtraction is of at most 0:

[tex]H_0: \mu_1 - \mu_2 \leq 0[/tex]

At the alternative hypothesis, it is tested if it travels farther, that is:

[tex]H_1: \mu_1 - \mu_2 > 0[/tex]

Considering the three bullet points above, the correct option is a.

Answer:

If I understand the definitions correctly,

"surface area" would be the total of all the areas of an object, while "lateral" surface area would exclude the base

so the surface area of a square pyramid

= area of the square base + 4(area of the triangle)

That's my "formua".

In both #1 and #2 you then give dimensions H, W, and L without defining them. If the base is square, how come we have different (W)idths and (L)engths

in #3 Diameter = 8, thus radius = 4

height = 7

Thus slant height of cone = √(4^2 + 7^2) = √65

surface area = πr(r+√(h^2+r^2)

= 4π(4 + √65) = appr 151.58

or surface area = πr^2 + πrs, where s is the slant height

= π(16) + π(4√65) = 151.58

I got the same answer using 2 established methods, none of the answers given match that.
