Please answer this correctly

Alenkasestr [34]

Answer:

5/12

Step-by-step explanation:

The probability of rolling a number greater than 1 is 5/6, because 5 numbers on a 6-sided dice are greater than 1.

The probability of rolling an even number is 3/6, because 3 numbers on a 6-sided dice are even numbers.

$5/6 \times 3/6$

$=15/36$

$=5/12$

an investor invested a total of 2500 dollars in two mutual funds.one fund earned 5 percent profitwhile the other earned 3 percen

bonufazy [111]

Total investment=$2500

Let say David earned 5% profit and Harry earned 3% profit.

If David invested y dollar in mutual fund then Harry would invest,

Harry would invest,$(2500-y)

Total profit would equal to sum of 5% of money David invested and 3% of money Harry invested,

So,

5% × y +3% ×(2500-y)=total profit

0.05×y+0.03×(2500-y)=$111

0.05y+0.03×2500-0.03y=111

0.02y+75=111

0.02y=111-75

y=36/0.02

y=$1800

which is the amount David invested.

The amount invested by Harry would be,

=$(2500-1800)

=$700

Evaluate the radical. 1000−−−−√3

scoray [572]

( 1000 )^1/3
= ( 10 ^3 )^ 1/3

= ( 10 ) ^ 3 × 1/3

= 10

A graph Includes the ordered pair (2,4). Write two different rules that would be possible for this graph. Explain how you found

Vanyuwa [196]

We know that
An ordered pair is used to locate a point on a coordinate grid.
The first number in an ordered pair is the x-coordinate, and the second number in an ordered pair is the y-coordinate.

In this problem, the ordered pair is
$(2,4)$
so
the x-coordinate is equal to $2$
the y-coordinate is equal to $4$

therefore

Rule N 1
The y-value is $2$ times the x-value

Rule N 2
The y-value is $2$ greater than the x-value

Both are possible because their solutions include the ordered pair listed
