The answer is a trapezoid
Answer:
1/4
Step-by-step explanation:
Answer:
x = 16
m<R = 34°
Step-by-step explanation:
▪︎Its an isoceles triangle, so the two opposite angles are equal. m<S = <T.
▪︎So, you write them equal to each other and solve the linear equation to find <em>x</em><em>.</em><em> </em>
▪︎Substitute the x value into any of the angles and multiply by 2, (as they are equal) to find the sum, which is 146°.
▪︎Sum of all angles in a triangle is 180°,so
146° + m< R =180°
▪︎than minus 146° from 180°.
▪︎And you will have your answer.
Answer:
Step-by-step explanation:
Given that in order to efficiently bid on a contract, a contractor wants to be 95% confident that his error is less than two hours in estimating the average time it takes to install tile flooring.
Std deviation =4.5 errors
95% confidence interval = Mean±1.96*std dev
Hence we have
Sample size should be 20.
Answer:
You would get 80 cups to 60 seconds (1 minute)
Step-by-step explanation:
You need to change this to minute, 6 seconds can be multiplied by 10 to 60 seconds, which would be come 1 minute. Since you multiplied 6 seconds, you need to multiply 8 cups too. So 8 times 10 is 80, you get 80 cups in 1 minute.
