Answer:
D = 90°
Step-by-step explanation:
the square on the angle means its a right angle and right angle is always 90°
Answer:
39 : 13 : 26 or 78 cookies total
Step-by-step explanation:
if following the rule, divide the normal amount of cookies by the total
(26 divided by 2 = 13)
then multiply that 13 with the other two numbers and thats your answer
#11 the top on in A connects with the bottom one in B, bottom one in A connects with Middle one in B, and middle one in A connects with the top one in B
Answer:
36°
Step-by-step explanation:
The computation of the measure of the angle is shown below:
As we know that
The trigonometric function in the right angle is
sinα = OS ÷ H
And,
cosα = AS ÷ H
Here
α represent the one of the angles
OS and AS represent the opposite sides
And, H represent the hypotenuse
So
sinx = 8.5 ÷ 14.5
x = arcsin = 8.5 ÷ 14.5
= 35.88
= 36 degrees
Answer:
(0.0706, 0.1294)
Step-by-step explanation:
Confidence interval of a proportion is:
CI = p ± CV × SE
where p is the proportion,
CV is the critical value (z score or t score),
and SE is the standard error.
The sample is large enough to estimate as normal. For 95% confidence level, CV = z = 1.96.
Standard error for a proportion is:
SE = √(pq/n)
SE = √(0.1 × 0.9 / 400)
SE = 0.015
The confidence interval is:
CI = 0.1 ± (1.96)(0.015)
CI = (0.0706, 0.1294)
Round as needed.
