Answer:
13.8
Step-by-step explanation:
Recall the trigonometric ratios
Sine = Opposite over Hypotenuse (SOH)
Cosine = Adjacent over Hypotenuse (CAH)
Tangent = Opposite over Adjacent (TOA)
Now lets look back at the question
We are given an angle and its adjacent side length (11) and we need to find the hypotenuse
The hypotenuse and adjacent sides corresponds with the trig function cosine so we will use cosine to solve for x
( remember that cosine = adjacent over hypotenuse )
step 1 multiply each side by x
now we have
step 2 divide each side by cos(37)
we're left with x = 13.77439
Our last step would be to round to the nearest tenth
We would get that the answer is 13.8

Step-by-step explanation:
Given : Sample size of cars : n= 150, sample size is greater than 30 , so we use z-test.
Number of cars tested do have faulty catalytic converters =42
Then the proportion of cars have faulty catalytic converters :
Critical value of z for 99% confidence level :
Formula for Margin of error :
Hence, the required margin of error =
Answer:
You didn't provide answer options. The correct answer option will be the one where the ratio of red paint to yellow paint is 3:8.
Step-by-step explanation:
To make orange, you need some amount of red and some amount of yellow. As long as you mix them in the same proportions, you will get the same orange colour, regardless of how much total paint you're using. It's the RATIO between colours that matter, not how much colour is used.
In this case we are told that to make orange you can use any of the following combinations:
10.5mL red / 28mL yellow
9mL red / 24mL yellow
7.5mL red / 20mL yellow
Just take any of these and convert into a fraction. The middle option is easiest because it uses whole numbers:
This means for every 3 units of red, you need 8 units of yellow. Whichever answer option has red and yellow in that ratio is the correct answer.
