The number of clocks that are not defective is an illustration of proportions

Of the 10000 clocks, 9250 are probably not defective

<h3>How to determine the number of clocks that are not defective?</h3>

From the complete question, we have the following parameter:

15 out of 200 clocks are defective

The above means that the number of clocks that are not defective is:

Not defective = 200 - 15

Not defective = 185

Express as percentage

Not defective = 185/200

Not defective = 92.5%

In 10,000 the number of clocks that are not defective would be:

Not defective = 92.5% * 10000

Not defective = 9250

Hence, 9250 of the 10000 clocks are probably not defective

A = 27 + 0.3 C

Answer:

The amount of potassium chloride that can dissolve in water increases by 0.3 grams for every 1 degree Celsius increase in temperature.

Explanation:

Given

$A = 27 + 0.3C$

Required

Interpret 0.3

We make use of the following illustration to answer this question.

Let C = 1

$A = 27 + 0.3*1 = 27 + 0.3 = 27.3$

Let C =2

$A = 27 + 0.3*2 = 27 + 0.6 = 27.6$

Let C = 3

$A = 27 + 0.3*3 = 27 + 0.9 = 27.9$

Notice that when the values of C increases by 1(i.e. from 1 to 2 and 2 to 3), the values of A increases by 0.3

i.e.

$27.9 - 27.6 = 27.6 - 27.3 = 0.3$

Hence, option D is true

Ans is C can anyone explain this?????

vladimir1956 [14]

In an isosceles triangle ! Two angles and two sides are equal. If angle b is greater than a then angle a= angle c (since b is not equal to a). This means that the adjacent sides of angle a and angle c will be equal. In this case the sides AB and BC are equal. Angle a= angle c. In this case AB is NOT equal to AC and AC is NOT equal to BC. #answerwithquality #BAL
