Answer:

1.) 20,160 cookies, 2.) 37,600 Letters to students in a different country 3.) 252.36 Exact form, Approximate form: 252

Step-by-step explanation:

The first question is written in standard form like this:

Standard Form: 315 x 64 = 20,160

Algebraically/Logical: 315 Packages x 64 Cookies = 20,160 Cookies in All

Therefore, Kenneth bought 20,160 Cookies

The second question is written like this:

Standard Form: 940 x 40 = 37,600

Algebraically/Logical Reasoning: 940 students x 40 letters = 37,600 letters written to students in a different country.

Note: This question has a random P 240, That will be erased so that is why the equation is 940 x 40

The third question is written like this:

Standard Form: 36 x 7.01 = 252.36

Approximate form: 36 x 7 = 252

Algebraically/Logical Reasoning: The standard form would explain it all but if I was answering this question I would round 7.01 to the one's place because there is no way you would get a decimal when trying to solve an even amount of cloths. So there are 36 squares in one table cloth, times that by 7 which is equal to 252 approximently.

Answer:

The probability of a person having a driving accident while intoxicated is 0.07

Step-by-step explanation:

Hi, well, let´s put this on a formula, I think it is the best way to explain it.

$P(A+I)=P(A)+P(I)-P(AorI)$

Where:

P(A+I) = Probability of having a driving accident while intoxicated.

P(A) = Probability of a person of having an accident.

P(I) = Probablity person being intoxicated.

P(A or I) = Probability of a person for being intoxicated or having an accident.

Therefore, things should look like this:

$P(A+I)=0.12+0.32-0.37=0.07$

So, the probability of a person having a driving accident while intoxicated is 0.07.

Best of luck.

What is the measure of the angle between the hour hand and the minute hand when it is 7:00 and 2:00

sergij07 [2.7K]

Answer:

150 degrees or 210 degrees

Step-by-step explanation:

A circle is equal to 360 degrees. The face of a clock is a circle and therefore 360 degrees. A clock is separated into 12 sections. Divide 360/ 12 = 30 degrees. This means each section is 30 degrees.

Between 2:00 and 7:00 clockwise, there are 5 sections. Since each section is 30 degrees, then 5*30 = 150 degrees.

Between 2:00 and 7:00 counter clockwise, there are 7 sections. Since each section is 30 degrees, then 7*30 = 210 degrees.

The angle depends on the direction of it.
