Answer:

1.875 or 1\frac{7}{8} cups of pretzel

Step-by-step explanation:

The number of cups needed is equivalent to the probability of pretzel in the mix times the number of cups in the mix.

-The probability of pretzel is :

P(pretzel)=\frac{0.2}{0.25+0.25+1.5}\\\\=0.125

We multiply this probability by the number of cups of the mix:

=P(pretzel)\times (mix \ cups)\\\\=0.125\times 15\\\\=1.875 \ or \ 1\frac{7}{8}

Hence, 1.875 or 1/7/8 cups of pretzel is needed.

ira [324]

Answer:

The maximum value of the confidence interval for this set of survey results is 51.73%.

Step-by-step explanation:

A confidence interval has two bounds, a lower bound and an upper bound.

These bounds depend on the sample proportion and on the margin of error.

The lower bound is the sample proportion subtracted by the margin of error.

The upper bound is the margin of error added to the sample proportion.

In this question:

Sample proportion: 46.1%

Margin of error: 5.63%.

Maximum value is the upper bound:

46.1+5.63 = 51.73

The maximum value of the confidence interval for this set of survey results is 51.73%.

The diameter of a circle is 10 cm what is the angle measure of an arc Pi centimeters long
vredina [299]
We know that

[length of a circumference]=2*pi*r
diameter=10 cm
r=10/2-----> 5 cm
[length of a circumference]=2*pi*5-----> 10*pi cm

if 360° (full circle) has a length of -----------> 10*pi cm
 X°---------------------------> pi cm
X=pi*360/10*pi------> 36°

the answer is 36°
