the first part isn't 90, it's 180.
the whole circle is 360, half of 360 is 180
an acute angle is any angle less than 90 degrees.

Step-by-step explanation:
It takes 147.87 milliliter to make ice cube
<em><u>Solution:</u></em>
Given that ice cube is made of 5 fluid ounces of water
To find: milliliters of water to make to the ice cube
So we have to convert 5 ounce to milliliter
<em><u>Use the following conversion factor</u></em>
1 ounce = 29.5735 milliliter
Therefore,
5 ounce = 5 x 29.5735 milliliter
5 ounce = 147.8675 milliliter
On rounding to nearest hundred ( 2 decimal places ) , we get
5 ounce = 147.87 milliliter
Thus it takes 147.87 milliliter to make ice cube
Answer:
The answer is false
Step-by-step explanation:
In a sample above 30 obs like this the confidence interval is defined as
X+- t* (s/sqrt(n)) where X is the mean t the tvalue for a given confidence level, n the size of sample and s standar deviation.
To find de appropiate value of t we must see the T table where rows are degrees of freedom and columns significance level
The significance is obtained:
significance = 1 - confidence level = 1 - 0.9 = 0.10
Degrees of freedom (df) for the inteval are
df = n - 1 = 18 - 1 = 17
So we must look for the value of a t with 17 values and significance of 0.10 which in t table is 1.740 not 1.746 ( thats the t for 16 df)
