Find the probability. Enter your answer as a simplified fraction.

Mashcka [7]

Answer:

$\frac{1}{2}$ is your answer

Step-by-step explanation:

To calculate the probability, you first have to find the total things by adding.

13 + 13 = 26

Then, you find the number of purple marbles which is 13. So, 13 is the numerator, and 26 the denominator.

$\frac{13}{26}$

Next, simplify.

$\frac{13}{26} = \frac{1}{2}$

Have a wonderful day!

Tommy earned $76.00 in interest after 5 years on a principal of $400. Jane earned $82.00 in interest after 2 years on a principa

vovikov84 [41]

Answer:

The bank in which Jane has invested.

Step-by-step explanation:

For Tommy's Bank:

P = $400

t = 5 years

I = $76

Simple interest formula is given by

$I=Prt\\\\76=400(r)5\\\\r=0.038\\\\r=3.8\%$

For Jane's Bank:

P = $1000

t = 2 years

I = $82

Simple interest formula is given by

$I=Prt\\\\82=1000(r)2\\\\r=0.041\\\\r=4.1\%$

Since, Jane's bank has higher interest rate. It means one can get higher interest if invest in this bank.

Therefore, we should prefer the bank in which Jane has invested.

Solve for x.<br> 0.9(5x+4) = 5.7 2.5X

Alenkinab [10]

Answer:

x=0.369231

Step-by-step explanation:

0.9(5x+4)=5.7(2.5x)

Step 1: Simplify both sides of the equation.

0.9(5x+4)=5.7(2.5x)

(0.9)(5x)+(0.9)(4)=5.7(2.5x)(Distribute)

4.5x+3.6=14.25x

Step 2: Subtract 14.25x from both sides.

4.5x+3.6−14.25x=14.25x−14.25x

−9.75x+3.6=0

Step 3: Subtract 3.6 from both sides.

−9.75x+3.6−3.6=0−3.6

−9.75x=−3.6

Step 4: Divide both sides by -9.75.

−9.75x/ −9.75 = −3.6/ −9.75

x=0.369231
