Answer:

0.1137= 11.37%

Step-by-step explanation:

Assuming there are 365 days in one year and every people have 1 birthday, then the chance for two people to have the same birthday is 1/365 and the chance they are not is 364/365. We are asked the chance for at least one match among 44 people. The opposite of the condition is that we have 0 matches and easier to calculate. The calculation will be:

P(X>=1)= ~P(X=0) = 1

P(X>=1)=- P(X=0)

P(X>=1)=1 - (364/365)^44

P(X>=1)=1- 0.8862

P(X>=1)=11.37%

Janelle and her best friend Carmen go shopping. the function p(t) = 5^4-3x^3 +2^2+24 represents how much money each girl spent b

emmasim [6.3K]

<h2>Hello!</h2>

The answer is:

They spent $176 together.

We are given an expression which represents the money spent for each girl, it's a function of time and it will show how much they can spend in terms of hours.

Assuming that you have committed a mistake writing the equation, otherwise, the given options would not fit, the expression is:

$p(t)=5x^{4}-3x^{3}+2x^{2}+24$

Now, from the statement we know that the function represents how much money each girl spent, so, if we need to calculate how much money they will spend together, we need to multiply the expression by 2, so we have:

$p(t)=2(5x^{4}-3x^{3}+2x^{2}+24)$

Then, calculating the spent money for 2 hours, we need to substitute the variable "x" with 2.

Calculating we have:

$p(2)=2(5*(2)^{4}-3*(2)^{3}+2*(2)^{2}+24)=2(5*16-3*8+2*4+24)$

$p(2)=2(5*16-3*8+2*4+24)=2(80-24+8+24)=2*88=176$

Hence, we have that they spent $176 together.

Have a nice day!

7,080,267 written in expanded form

Alex787 [66]

If you know the definition of expand (to increase or make bigger)
then this will be easy.

when ever it asks for expanded for that means your answer has to be bigger than the number your given.

for your question:
you have 7,080,267

so u first do the biggest value which is the first 7 on the left.
and then work your way down to the smallest which would be 7 on the right.

7000000
000000
80000
0000
200
60
7
that is the numbers expanded

but now u have to write it in the fom so you just add a + after each number

7000000+000000+80000+0000+200+60+7
you can shorten it by removing the numbers with no value:
7000000+80000+200+60+7

A diamond ring was reduced from $999.99 to $699.99. Find the percent decrease in the price. Round the answer to the nearest tent

poizon [28]

Answer:

30.0% decrease.

Step-by-step explanation:

A diamond ring was reduced from $999.99 to $699.99

The decrease is; $999.99 - $699.99 = $300.00

Percentage decrease = $\frac{decrease}{original price}$ × 100

i.e percentage decrease = $\frac{300}{999.99}$ × 100 = 30.0003%

And it equals to 30.0% (rounded off to the nearest tenth of a percent)
