I can’t solve it plz help me!!!

Answer:

= 21

Step-by-step explanation:

Answer:

sinB = 21/75

tanB = 21/22

Step-by-step explanation:

sinΦ = Height / Hypotenuse

tanΦ = Height / Base

Answer:

sin B = 7/25, tan B = 7/24

Step-by-step explanation:

sin = opposite / hypotenuse, tan = opposite / adjacent

Maybe I missed something but all I did was recreate your triangle and solve the trig ratios.

Answer:

hello your question lacks some information attached below is the complete question

answer : NO

Step-by-step explanation:

Determine the probability of not selecting an obese subject in 3 trials

= P ( not obese in 3 randomly selected ) = ( 1 - 0.111 )^3

= 0.703

The probability > 0.05

hence it is insignificant therefore the answer is NO

Answer:

D. Absolute value

Step-by-step explanation:

There are absolute value bars around x, so the function is absolute value.

Hope this helps...have a great day ^^

Answer:

<STP=105°

Step-by-step explanation:

two interior angles equal one opposite exterior angle therefore

7x+6+7x+1=15x

group like terms

6+1=15x-7-7

7=15x-14x

7=x

for 15x

15 will multiply 7 and that is 105

Answer:

Step-by-step explanation:

sin(0) = 0/2

sin(30) = 1/2

sin(45) = [tex]\sqrt{2}[/tex]/2

sin(60) = [tex]\sqrt{3}[/tex]/2

sin(90) = [tex]\sqrt{4}[/tex]/2

cos(90) = 0/2

cos(60) = 1/2

cos(45) = [tex]\sqrt{2}[/tex]/2

cos(30) = [tex]\sqrt{3}[/tex]/2

cos(0) = [tex]\sqrt{4}[/tex]/2

notice that sin and cos repeat,   but in reverse

the answer for your questions is in there.  

Answer:

Yes it is.

Step-by-step explanation:

There are two ways to do this.

1: Find a common denominator, such as _/24. First, you do how many times does 6 go into 24? Well, 4, so then do 4x4 = 16/24 then do the same thing for 8. 8x3=24, so 2x3=6/24. So 16/24 is greater than 6/24.

2: 4/6 = 0.667 and 2/8 = 0.25. So yes, 0.667 is greater.

*Hope this Helps*

Put simply, yes.

To prove, find like denominators, then compare numerators.

Factors of 6: 6, 12, 18, 24, 30, 36

Factors of 8: 8, 16, 24, 32, 40, 48

The LCF is 24.

[tex]\frac{4}{6}*4=\frac{16}{24}[/tex]

[tex]\frac{2}{8}*3=\frac{6}{24}[/tex]

Now compare numerators.

16 > 6

So yes, 4/6 is greater than 2/8.

Hope this helps. Have a nice day.

then take the combined wait and divide the total amount of snacks by it

48/30 = 1.6

Answer:

About 207 inches

Step-by-step explanation:

The circumference of a circle is given by the formula ...

 C = πd . . . . . where d represents the diameter

The circumference of the tire is the distance the truck will move when the tire makes one revolution. That distance is ...

 C ≈ 3.1416×(66 in) ≈ 207.35

The truck will travel about 207 inches for each revolution of the tire.

Answer:

The 96% confidence interval for the proportion of people who say they jog regularly is between 0.1222 and 0.1578. This means that we are 96% sure that the true population proportion of people who jog is between 0.1222 and 0.1578.

With a 99% confidence level, the interval would be wider.

The smallest number of people we could contact to still have a margin of error of 3% at a 96% confidence level is 566.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

A polling organization contacts 1600 people and of these 14% say that they jog regularly.

This means that [tex]n = 1600, \pi = 0.14[/tex]

Construct and interpret a 96% confidence interval for the proportion of people who say they jog regularly.

96% confidence level

So [tex]\alpha = 0.04[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.04}{2} = 0.98[/tex], so [tex]Z = 2.056[/tex].

Margin of error:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M = 2.056\sqrt{\frac{0.14*0.86}{1600}}[/tex]

[tex]M = 0.0178[/tex]

Lower bound:

Sample proportion subtracted by the margin of error. So

[tex]\pi - M = 0.14 - 0.0178 = 0.1222[/tex]

Upper bound:

Margin of error added to the sample proportion. So

[tex]\pi + M = 0.14 + 0.0178 = 0.1578[/tex]

The 96% confidence interval for the proportion of people who say they jog regularly is between 0.1222 and 0.1578. This means that we are 96% sure that the true population proportion of people who jog is between 0.1222 and 0.1578.

Explain what changes if you instead use a 99% confidence level.

With a 99% confidence level, the value of Z would be higher(2.575), which means that the interval would be wider.

What is the smallest number of people we could contact to still have a margin of error of 3% at a 96% confidence level.

This is n for which [tex]M = 0.03[/tex]

So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 2.056\sqrt{\frac{0.14*0.86}{n}}[/tex]

[tex]0.03\sqrt{n} = 2.056\sqrt{0.14*0.86}[/tex]

[tex]\sqrt{n} = \frac{2.056\sqrt{0.14*0.86}}{0.03}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.056\sqrt{0.14*0.86}}{0.03})^2[/tex]

[tex]n = 565.5[/tex]

Rounding up:

The smallest number of people we could contact to still have a margin of error of 3% at a 96% confidence level is 566.

Step-by-step explanation:

225 x 4 /100  = 9

Answer:

Yes is just like using the slope intercept form

Step-by-step explanation:

Answer:

So if 14% are over 65, and 320 residents are over 65, then we can say that 14% of the town is 320. Then, we can divide by 14 to find 1%, which is 22.857142857 Now we can multiply this by 100 to get 2285.7142857.

Answer: 30 feet

Explanation:

The soccer player kicked the ball 30 feet

10 yards = 30 feet

Answer:

30 ft

Step-by-step explanation:

because their are 3 ft in a yard so

10x3=30 ft

Answer:

x = 10

Step-by-step explanation:

3x - 5 = 2x + 5

3x - 5 + 5 = 2x + 5 + 5

3x = 2x + 10

3x - 2x = 2x - 2x + 10

1x = 10

x = 10

Answer:

I think A

Step-by-step explanation:

3x5=15-5=10

2×5+5=15

So x = 10
