Answer:
1/4*1/3=1/2
Step-by-step explanation:
Answer:
angle 2 is 43 as the opposite side of the angle is always equal angle 1 and 3 are:
step 1
43+43=86
step 2
360-86=274
step 3
274÷4=68.5
we subtracted 86 with 360 because 360 is the sum of all the angles we then divided the answer by 2 as we were suppose to find two angles angle 1 and 3 are opposite angles so they both will be same
hope this information helps u :)
Answer:
-3
Step-by-step explanation:
<em>r</em> = 12
<em>s</em> = -4
<em>t</em> = -6
<u>Equation</u>
<em>rs</em> ÷ 16
12(-4) ÷ 16
-48 ÷ 16

Answer:
Her usual speed is 5 miles an hour.
Step-by-step explanation:
Since it takes one hour for her to run ten miles that means she is running at 10 miles an hour. So if you divide that by 2 it would be five.

Answer:
W= 5.744
Step-by-step explanation:
given that a grocery store produce manager is told by a wholesaler that the apples in a large shipment have a mean weight of 6 ounces and a standard deviation of 1.4 ounces
Sample size n= 49
Margin of error = 0.10 (10% risk )
Let us assume X no of apples having mean weight of 6 oz is N(6,1.4)
Then sample mean will be normal with (6, 1.4/7) = (6,0.2)
(Because sample mean follows normal with std error as std dev /sqrt of sample size)
Now required probability <0.10
i.e.
Since x bar is normal we find z score for

From std normal distribution table we find that z = 1.28
Corresponding X score =
