Survey: On free time 90 students like watching TV, 20 like watching TV but not reading, 80 like reading, 40 do not like watching TV. Question: Percent of total student like both watching televisan and reading
Answers
Answer:
50 %
Step-by-step explanation:
From the diagram attached,
Percentage of total students that like watching television = [(WnR)/μ]×100......... Equation 1
The number of students that like watching television and reading (WnR) = 70
The total number of students (μ) = 40+20+70+10
The total number of students (μ) = 140
Substitute these values into equation 1
Percentage of total students that like watching television = (70/140)×100
Percentage of total students that like watching television = 1/2(100)
Percentage of total students that like watching television = 50 %

What is the value of x?
Answers
Answer:
x = 39
Step-by-step explanation:
The angle between a tangent and the radius of a circle at the point of contact is 90° , then
x = 180 - (90 + 51) = 180 - 141 ← angle sum of triangle
x = 180 - 141 = 39
x + 51 = 90
x = 90 - 51
x = 39°

Answers
Answer: 700 customers
Step-by-step explanation:
In a random sample of 200, 140 people ordered French fries.
Find out the percentage of people who ordered French fries:
= 140 / 200
= 70%
If the restaurant usually has 1,000 customers a day, based on the rate of people who ordered French fries out of 200 people - 70% - the number of people who will probably order French fries are:
= 70% * 1,000

triangle ABC has side lengths 8 inches, 17 inches, and 15 inches. Sofia uses the following steps to conclude that triangle ABC is not a right triangle.
[tex]a^{2} +b^{2} =c^{2} \\8^{2} +17^{2} =15^{2} \\64+289=225\\353\neq 225[/tex]
What mistake did Sofia make?
A Sofia made a calculation error.
B Sofia used the length of one of the legs as c when she should have used the length of the longest side as c.
C Sofia does not know if triangle ABC is a right triangle, so she cannot use the Pythagorean Theorem or its converse.
D Sofia’s conclusion is incorrect. When the sides of a triangle do not satisfy a2+b2=c2, you cannot conclude that the triangle is a right triangle.

We sell ice cream at a retail store, which we operate 50 weeks per year. Whenever we order from our supplier we incur a $250 ordering charge. Customer demand is 200 pounds per week and it costs us $35 per pound per year to hold the ice cream in proper storage. a) What is the EOQ?
Answers
Answer:
the EOQ is 378 units
Step-by-step explanation:
The computation of the economic order quantity(EOQ) is shown below:
EOQ is
[tex]= \sqrt{\frac{2\times A\times O}{C} } \\\\= \sqrt{\frac{2\times 200 \times 50\times \$250}{\$35} }[/tex]
= 378 units
Here A represent the annual demand
O represent the ordering cost
And, C represent the carrying cost
hence, the EOQ is 378 units

8x - 4 + 7x + 4 = 180 , that is
15x = 180 ( divide both sides by 15 )
x = 12

∠ C = 7x + 4 = 7(12) + 4 = 84 + 4 = 88°
