Answer:

the circumference is 31.4

Step-by-step explanation:

The computation of the circumference is shown below:

As we know that

Circumference is

= 2πr

= 2π (10 ÷ 2)

= 2× 3.14 × 5

= 31.4

Hence, the circumference is 31.4

Step-by-step explanation:

m<2=49° (vertically opposite angles are equal)

m3=112° (vertically opposite angles are equal)

m1= 112°+ m1 =180 (the sum of interior angles measure 180°)

hence, m1 = 180 - 112°

m1= 68°

Answer:

A

Step-by-step explanation:

The true statement is

A 99% confidence interval for will include the value 1.

The range of values that we observe in our sample and for which we anticipate finding the value that accurately reflects the population is referred to as a confidence interval.

Given:

[tex]H_0: \mu = 1\\H_\alpha : \mu \neq 1[/tex]

P= 0.022

If the P- value is smaller than significance level, then the null hypothesis is rejected.

P< 0.05 - 5% Reject [tex]H_0[/tex]

P> 0.01 = 1% Fail to Reject [tex]H_0[/tex]

A 95% Confidence interval correspond with a significance test at the 5%

significance level.

A 99% Confidence interval correspond with a significance test at the 1%

significance level.

If the Significance test was Significant then the interval does not contain the value mentioned in the Hypothesis.

95% CI does not contains 1.

99% CI contains 1.

Answer:

sin2θ = [tex]\frac{1320}{3721}[/tex]

Step-by-step explanation:

Given

sinθ = [tex]\frac{11}{61}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]

This is a right triangle with legs 11 and x ( adjacent ) and hypotenuse 61

Using Pythagoras' identity in the right triangle to find x

x² + 11² = 61²

x² + 121 = 3721 ( subtract 121 from both sides )

x² = 3600 ( take the square root of both sides )

x = [tex]\sqrt{3600}[/tex] = 60

Then cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{60}{61}[/tex]

Using the identity

sin2θ = 2sinθcosθ , then

sin2θ = 2 × [tex]\frac{11}{61}[/tex] × [tex]\frac{60}{61}[/tex] = [tex]\frac{1320}{3721}[/tex]

Step-by-step explanation:

The cost of each brownie is $1.25

Let the cost of each brownies be x

If she buys 12 brownies and each brownie costs the same amount, the cost of 12 brownies will be 12x

To find the value of x;

39.99 = 24.99 + 12x

12x =  15

x = 15/12

x = $1.25

Hence the cost of each brownie is $1.25

Answer:

The total distance Remy will swim is approximately 236 meters

Step-by-step explanation:

From the given diagram, of triangle ΔCAB, we have that the path Remy is to swim are;

1) Length of segment C to A

2) Length of segment A to B

3) Length of segment B to C

The length of the perpendicular at point D on segment AB to C = 60 meters

Therefore, DC = 60 m

By trigonometric ratios, we have;

[tex]tan (\theta) = \dfrac{Opposite \ leg \ length}{Adjacent \ leg \ length}[/tex]

[tex]cos(\theta) = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]

We are given the values of the trigonometric ratios of the following angles;

tan(27°) = 0.51

tan(43°) = 0.93

cos(27°) = 0.89

cos(43°) = 0.73

∴ tan(43°) = AD/DC = 0.93

Where the lengths of AC, AD, DB, DC and BC

AD = DC × tan(43°)

∴ AD = 60 × 0.93 ≈ 55.8

Similarly, we have;

tan(27°) = DB/DC

∴ DB = DC × tan(27°)

DB = 60 × 0.51 ≈ 30.6

From [tex]cos(\theta) = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex], we have;

cos(43°) = DC/AC

AC = DC/(cos(43°))

∴ AC = 60/0.73 ≈ 82.2

Similarly, we have;

cos(27°) = DC/BC

BC = DC/(cos(27°))

∴ BC = 60/0.89 ≈ 67.4

The total distance Remy will swim = AC + AD + DB + BC

∴ The total distance Remy will swim = 82.2 + 55.8 + 30.6 + 67.4 = 236

The total distance Remy will swim = 236 meters

Answer:

The last option

Step-by-step explanation:

You can find the slope by using this equation : y2-y1/x2-x1. We can choose any two y coordinates and any two x coordinates to find this. For instance, you can write this as -3-(-2.25)/0-(-1). Now, we can solve.

-3-(-2.25)/0-(-1)

-3+2.25/0+1

-0.75/1

-0.75

-0.75 in fraction form is -3/4.

I'm not quite sure how to calculate the y-intercept, but we know the slope, and that's all we need for this problem (the slope number is next to the x). This makes our answer the last option. Hope this helps!
