Answer:

-22

Step-by-step explanation:

PEMDAS!

Solve (15 ÷ 5 × 6) first. This is equal to 18.

$3^2$ + 18 - 49

$3^2$ is equal to 9.

9 + 18 - 49 = -22

Max tosses a Fair coin 3 times what is the probability of getting heads in the first two trials and Tails in the last trial

Gennadij [26K]

.5 * .5 *.5 = 1/8
-
-
the probability to have head is .5 so the probability of tails 1-.5
-
then the first time is head
the second time is head
the third time is tail
so
.5 * .5 *.5 = 1/8

Answer:

(1) 820

(2) 1920

Step-by-step explanation:

(1) solving 20 x 41, using associative property.

20 * 41 = (2 x 10) x 41 = 2 x (10 x 41)

= 20 x 41 = 2 x 410

= 820 = 820

(2) distribute 32 as 30 + 2 and solve.

60 x 32

= 60 x (30 + 2) = 60(30) + 60(2)

= 1800 + 120

= 1920

You pick 5 digits (0-9) at random without replacement, and write them in the order picked. What is the probability that you have

Tanzania [10]

Answer:

Probability is : 1/30240= 0.000033068

Step-by-step explanation:

You pick 5 digits (0-9) at random without replacement, and write them in the order picked.

The probability that you have written the first 5 digits of your phone number is -

As there are no repeats, the choice to choose from decreases at each step making it 10,9,8,7,6.

$(1/10)(1/9)(1/8)(1/7)(1/6)=1/30240= 0.000033068$

The larger of two numbers is 7 times the smaller number. Three times the larger number is 7 more than 4 times the smaller number

Juliette [100K]

Let the smaller number be x.

Given, the larger number is 7 times the smaller number.

So, the larger number = 7x.

Given, 3 times the larger number is 7 more than 4 times the smaller number.

So we can write the equation as,

$3(7x) = 4(x)+7$

$3(7x) = 4x+7$

$21x = 4x+7$

Now we have to move 4x to the left side by subtracting 4x from both sides.

$21x-4x = 4x-4x+7$

$21x-4x = 7$

$17x = 7$

To get x, we will divide both sides by 17. We will get,

$\frac{17x}{17} = \frac{7}{17}$

$x = \frac{7}{17}$

So the smaller number = $\frac{7}{17}$

The larger number = $7(\frac{7}{17} )$ = $\frac{49}{17}$

So we have got the required numbers.

Smaller number = $\frac{7}{17}$ and larger number = $\frac{49}{17}$ .
