Answer:

We can divide the pack of cards in two ways

Non Ace cards and Ace cards

Since there are 4 aces in a pack

No of non ace cards will be 52–4=48

The question mentions atleast 1 ace cards so i can pick 1 ace card,2 ace cards or 3 ace cards

Case1:1 Ace card

1 will pick one ace card and 2 non ace cards

It can be done in 4C1*48*C2 ways

= 4*1128 = 4 512 ways

Case 2: 2 Ace Cards

I will pick 2 ace cards and 1 non ace card

It can be done in 4C2 * 48C1 = 6 * 48 =288 ways

Case 3:3 Ace cards

It can be done in 4C3 =4 ways

Therefore the probability is

(4512+288+4)/52C3

=4804/22100=0.217

Answer:

O A. 26

Step-by-step explanation:

26 has occurred maximum number of times.

So, Mode of the given data value is 26

Answer:

z = 1.28 < a - 200/20

And if we solve for a we got

a = 200 + 1.28 * 20 = 225.6

So the value of height that separates the bottom 90% of data from the top 10% is 225.6.  

Step-by-step explanation:

Let X the random variable that represent the scores of a population, and for this case we know the distribution for X is given by:

X ~ N (200,20)

For u = 200 and o = 20

For this case we can use the z score in order to solve this problem, given by this formula:

Z = x-u/o

For this part we want to find a value a, such that we satisfy this condition:

P (X > a) = 0.1 (a)

P (X < a) = 0.9 (b)

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.  

As we can see on the figure attached the z value that satisfy the condition with 0.9 of the area on the left and 0.1 of the area on the right it's z=1.28. On this case P(Z<1.28)=0.9 and P(z>1.28)=0.1

If we use condition (b) from previous we have this:

P ( X < a) = P (X-u/o < a - u/o) = 0.9

P (z < a-u/o) = 0.9

But we know which value of z satisfy the previous equation so then we can do this:

z = 1.28 < a - 200/20

And if we solve for a we got

a = 200 + 1.28 * 20 = 225.6

So the value of height that separates the bottom 90% of data from the top 10% is 225.6.  

Answer:

what he works 40 hours overtime? im a little confused by the question but if he works 40 hours overtime then his gross pay would be $14,601.00.

Step-by-step explanation:

in order to calculate gross time you must first

Determine the actual number of hours worked.

Multiply the number of hours worked by the hourly wage.

If there is overtime, multiply the number of overtime hours worked by the overtime pay rate.

Add regular pay and overtime pay together to find the gross pay for that pay period.  hope this helps :) if not comment let me know

Answer:

762.6

Step-by-step explanation:

If he gets paid 18.60 per hour and he worked 41 hours then his total pay is $762.6

Answer:

He travelled 99 miles and has 351 miles to travel

Step-by-step explanation:

Here,

22/100×450

=22/2×9

=11×9

=99 miles travelled

Again,

450 miles - 99 miles

= 351 miles left to travel

(would appreciate it if you could mark me the brainliest :))

Answer:

Terrence has traveled 99 miles.

He still has 351 miles to go.

Step-by-step explanation:

Change 22% to a decimal by moving the decimal point two places to the left, or dividing by 100.

22% is .22

or 22/100 is .22

Multiply.

.22 × 450 = 99

Terrence traveled 22 miles.

His trip will be 450 miles. Subtract.

450 - 99 = 351

He has 351 miles to go.

Answer:

3 is your answer

Step-by-step explanation:

y divided by x gives the proportionality

3

To find the constant of proportionality, you divide x from y.

6/2= 3

9/3= 3

12/4= 3

15/5= 3

So, the constant of proportionality is 3.

Answer:

c.

10

Step-by-step explanation:

hope that help's u :))

The value of y is 10 after executing the statements because the addition of numbers, subtraction, multiplication, and division option (c) 10 is correct.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

The value x = 4

y = x + 1

y = 4 + 1

y = 5

The number expression can be defined as the combination of constants and variables with mathematical operators.

x= 3

y = 5(2)

y = 10

Thus, the value of y is 10 after executing the statements because the addition of numbers, subtraction, multiplication, and division option (c) 10 is correct.

Before solving these type of questions , have a look on the pie chart , from their we got that , 16% of 300 have choosed mystery as their favourite book.

Now , 16% of 300 = (16/100)×300 = 16×3 = 48

So , 48 people choosed mystery as their Favourite book .

Hence , Option C) 48 is correct

Answer:

Answer: 320 g

Step-by-step explanation:

We can set up a ratio.

Let the amount of oats equal to x.

18/240 = 24/x

We can now cross multiply.

18x = 5760.

x = 320 g

Answer:

[tex]320\ g[/tex]

Step-by-step explanation:

Start by setting up a ratio:

[tex]\frac{\text{amount of oats}}{\text{number of pancakes}}=\frac{\text{amount of oats}}{\text{number of pancakes}}[/tex]

[tex]\frac{240g}{18\text{ pancakes}}=\frac{xg}{24\text{ pancakes}}[/tex]

Cross multiply (Multiply the numerator of the first fraction by the denominator of the second and vice versa):

[tex]240*24=18*x\\5760=18x\\\text{Divide both sides by 18}\\x=320\ g[/tex]

Answer:

( 7 , 4 )

given:

make y the subject in equation 2:

4x - y = 24

-y = 24 - 4x

y = 4x - 24

insert this in equation 1:

4x + 10y = 68

4x + 10(4x - 24) = 68

4x + 40x - 240 = 68

44x = 68 + 240

44x = 308
