The answer is A or the first on you might say, hopes this helps ya!
If 3/8 of the recipe is going to be made, then u will need 3/8 of the sugar as well
3/8 of 3 1/4 cups would be needed
3/8 * 3 1/4 =
3/8 * 13/4 =
39 / 32 =
1 7/32 cups of sugar <=
Answer:
Step-by-step explanation:
Using this table, the critical value for the 90% confidence level is 1.645 (note: look in the row that starts with infinity and look for the value above 90%)
So z = 1.645
Given Information:
n = 40
s = 32
A hospital emergency room has collected a sample of n = 40 to estimate the mean number of visits per day. It has found the standard deviation is 32. Using a 90 percent confidence level, what is its margin of error?
-------------
sample mean:: x-bar = 40
ME = 1.645(32/sqrt(40)) = 8.32
Answer:
58° , 122° , 29°
Step-by-step explanation:
The triangle on the left has 2 congruent sides thus is isosceles.
Then the 2 base angles are congruent, so
∠ 1 = = = 58°
∠ 2 and 58° are adjacent angles and supplementary, that is
∠ 2 + 58° = 180° ( subtract 58° from both sides )
∠ 2 = 122°
The triangle on the right has 2 congruent sides and is isosceles
Then the 2 base angles are congruent, so
∠ 3 = = = 29°
Answer:
If you first start with 10% of 0.99 which is 0.099 then do 1% of 0.99 which will= 0.0099 then times the 0.0099 to get 5% which is 0.0495 then you do 0.099+0.0495 which equals 0.1485 then minus 0.1485 from 0.99 which is 0.8415
