Answer:

30 students

100 ÷ 20 = 50

60 ÷ 2 = 30 students

30 of the 50 students are 12 years old.

Step-by-step explanation:

60% of 50

60 : 100

X : 50

60/100 × 50

3/5 × 50 = 30

Answer:

60 ÷ 2 = the number of students who are 12 years old.

60 ÷ 2 = 30 students

30 of the 50 students are 12 years old.

Step-by-step explanation:

Change the percent to a decimal

.60 *50 =30

We can rewrite the decimal as a fraction

60/100 *50

We can change the order

60 * 50/100

60 *1/2

Multiplying by 1/2 is the same as dividing by 2

60 ÷ 2 = the number of students who are 12 years old.

60 ÷ 2 = 30 students

30 of the 50 students are 12 years old.

0 A maker of a certain brand of low-fat cereal bars claims that the average saturated fat content is 0.5 gram. In a random sampl

balandron [24]

Answer:

The first step is to determine the average

$x= \frac{0,6+0,7+ 0,7+0,3+0,4+ 0,5+ 0,4 +0,2}{8}\\\ x= 0,475$

The exercise says it’s a normal distribution: (n=8)

$s^{2}= \frac{1}{n-1} ((0,6.x)^2+2(0,7-x)^2+(0.3-x)^2+2(0.4-x)^2+(0.5-x)^2+(0.2-x)^2)\\\ \frac{1}{7}*0,235 = 0,0336 \\\\ s= 0183$

According to the exercise, the mean is equal to 0,5 then the value of t of the distribution can be obtained

$t= \frac{x-u}{\frac{s}{\sqrt{n} }}\\\ t= \frac{0,475 - 0,5}{0,183}\\\ t= -0,3860$

The variable t has 7 grade to liberty, we calculate the p-value as:

$2* P(t < - 0,3860)= \\\ 2* 0,3554 = 0,7108$

This value is very high, therefore the hypothesis is not rejected

A jeweler is making a triangular pendant. He has two sides of length 23 mm and 31 mm. What are the

denis-greek [22]

Answer:

38.60mm

Step-by-step explanation:

Step one:

Given data

We are given that the dimension of the triangles are length 23 mm and 31 mm

Let us assume that the triangle is a right angle triangle

Step two:

Applying the Pythagoras theorem we can find the third as

$z^2= x^2+y^2\\\\z^2= 31^2+23^2\\\\z^2= 961+529\\\\z^2= 1490\\\\$

square both sides

z= √ 1490

z= 38.60mm

Hence a possible dimension of the third side is 38.60mm
