Find the value of a that satisfies the following

P(Z>a)=0.9207

Answers

Answer 1

Answer:

-1.409

Step-by-step explanation:

I’m assuming this a z-score for stats. You would just go into your calculator, in my case a Casio. Then, you’d press on the stats module, click F5 (DIST), F1 (NORM), F3 (InvN). You would change the data to variable, then put in tail right, area .9207, SD 1, mean of 0. Then hit execute and you’ll get the answer of -1.4097958. Round it if needed.

Least common denominator is 10

2/5 = 4/10

10/10 - 5/10 - 4/10 = 1/10

if carl runs 4 laps in 18 minutes, how many laps can he run in 1 1/2 hours

Answers

Answer:

20 laps

Step-by-step explanation:

18 divide by 4 = 4.5

so 1 lap equals 4.5 minutes

and 1 and half hours is 90 minutes so 90 divide by 4.5 = 20 laps

He can run 20 laps.

90 minutes is 1 1/2 hours
We setup the equation to solve:

4/18=x/90

Solve for x by isolating and then cross multiply.

2/9=x/90

Cross multiply,

180=9x

Swap sides,

9x=180

Divide both sides by 9

X=20 :)

Answers

Answer:

2.5 hours

Step-by-step explanation:

→ Write the formula

Speed = Distance ÷ Time

→ Find the distance for 3 hours at a speed of 50 mph

Distance = Speed × Time ∴ 3 × 150 = 150

→ Now work out the time

150 ÷ 60 = 2.5 hours

How many phone numbers without area codes are possible? the first digit cannot be zero or one.

Answers

Ok guys, let me explain in a way you can understand.

let’s say there’s 7 blanks :

_ _ _ _ _ _ _

the first can’t be 0 or 1 so that means that it can be 2,3,4,5,6,7,8,9 which is 8 numbers

Now we have settle what the first digit can or can’t be, there are 6 numbers left.

Because there are no more restrictions for phone numbers that don’t work (first digit can’t be one or zero was the only restriction), the question then becomes : How many 6 digit numbers are possible (000000) can count , well we know that the biggest 6 digit number is 999999 and the smallest is 000000. That means there are 999999–000000+1 numbers between them inclusive. For those of you that are curious how I got the plus one, when you are counting the amount of numbers between let’s say a and b inclusive, the amount of numbers between them inclusive is |a-b| +1. Example : The amount of numbers between 2 and 13 inclusive is just |2–13|+1 which is 12. 2,3,4,5,6,7,8,9,10,11,12,13 is 12 numbers so |a-b|+1 works for the amount of numbers between a and b inclusive.

Anyways, back to the problem. 999999–000000+1 means there are 1000000 or 1 million possible 6 digit numbers. But that’s not the answer to the problem because each 1 of those 1 million 6 digit numbers needs a 7th digit which and be any number from 2–8 . This means that you need to multiply 1000000 by 8 to get 8 million possible phone numbers. If your wondering why I multiplied by 8, let’s say the number abcdef is one of the possible 6 digit numbers. If you add a 7th digit 2–9 to our number abcdef, then our number abcdef can be 2abcdef, 3abcdef, 4abcdef, 5abcdef, 6abcdef, 7abcdef, 8abcdef, 9abcdef.

Just a quick side note for any misconceptions, when I say the number abcdef, I don’t mean a times b times c times d times e times f, I mean a is the number in the hundred thousands place, b is the number in the 10 thousands place, c is the number in the thousands place, d is the number in the hundreds place, e is the number in the tens place, f is the number in the ones place.

Back to the problem, because there are 8 possible numbers for the 7th digit (AKA the first number in the phone number) you need to multiply the 1000000 different 6 numbers by 8 because each of those numbers has 8 variations.

In summary, there are 8*1000000 or 8 million different phone numbers whose digits aren’t 0 or 1

Answers

Answer:  H = {3, 5, 7}

Explanation:

We simply list any odd number that is between 2 and 8. The term "roster form" can be thought of as listing the roster of a sports team (eg: baseball). So instead of describing what the numbers look like, we list out the numbers themselves. Those numbers being 3, 5 and 7.

Something like {2,4,6,8} is ruled out because we're dealing with odd numbers only.

B. 10
C. 10 5/5

Answers

Answer:

A

Step-by-step explanation:

71/5 + 24/5 = N

Since the denominator is the same for both values, we can add them together.

71+24 / 5 = 95/5

We can prove this since 71/5 = 14.2 and 24/5 = 4.8

14.2 + 4.8 = 19

95/5 = 19
