Answer:

.47

Step-by-step explanation:

First you would substitute 2 for a, since that’s the amount of almonds bought.

5.20(2)+2.75r=11.70

Then you multiply 5.20 and 2

10.4+ 2.75r=11.70

Subtract 10.4 from each side of the equation to help isolate the variable

2.75r=1.30

And last you will divide each side by 2.75 to get the variable on its own. The final answer is .4727

Rounding would get you to .47

Answer:

$P(Ice Cream|Frogtown) = 67.4\%$

Step-by-step explanation:

Given

The attached plot

Required

P(Ice Cream|Frogtown)

This is calculated as:

$P(Ice Cream|Frogtown) = \frac{P(Ice\ Cream\ n\ Frogtown)}{P(Frogtown)}$

From the attachment;

$P(Ice\ Cream\ n\ Frogtown) = 0.31$

$P(Frogtown) = 0.31 + 0.15 = 0.46$

So, we have:

$P(Ice Cream|Frogtown) = \frac{P(Ice\ Cream\ n\ Frogtown)}{P(Frogtown)}$

$P(Ice Cream|Frogtown) = \frac{0.31}{0.46}$

$P(Ice Cream|Frogtown) = 0.6739$

Express as percentage

$P(Ice Cream|Frogtown) = 0.6739 * 100\%$

$P(Ice Cream|Frogtown) = 67.39\%$

$P(Ice Cream|Frogtown) = 67.4\%$ -- approximated

Which is the graph of f(x) = -(x + 3)(x + 1)?

Bas_tet [7]

Answer:

See attachment

Step-by-step explanation:

A function is given to us and we need to tell which graph represents the given function. The function given to us is,

$\tt: \implies f(x) = -( x + 3 )( x + 1 )$

Let's find out at which points do the graph Intersects x axis / finding the roots. For that substitute f(x) = 0 , we have ,

$\tt: \implies -(x +3)( x + 1 ) = 0$

Equate each factor by 0 ,

$\tt: \implies \boxed{\blue{ \tt x = -1,-3 }}$

Therefore the graph will intersect x axis at x is equal to -1 and x is equal to -3 .

On looking at the given graphs in the options the second graph intersects x axis at -1 and -3 .

Hence the second option is correct .

The growth of a sample of bacteria can be modeled by the function bt=1001.06t where b is the number of bacteria and t is time in

alukav5142 [94]

Given:

The growth of a sample of bacteria can be modeled by the function

$b(t)=1001.06t$

where, b is the number of bacteria and t is time in hours.

To find:

The number of total bacteria after 3 hours.

Solution:

We have,

$b(t)=1001.06t$

where, b is the number of bacteria and t is time in hours.

Substituting t=3, we get the number of total bacteria after 3 hours.

$b(3)=1001.06(3)$

$b(3)=3003.18$

Number of bacteria cannot be decimal value. So, approximate the value to the nearest whole number.

$b(3)\approx 3003$

Therefore, the number of total bacteria after 3 hours is about 3003.

Which measurement is not equal to 3 m 30 dm or 300 cm or 3000 mm or 3000 cm

Ainat [17]

3000cm because if you look at the variables there is no more letter m's than anything so if you cancel out and see what is equal to 30 then you get 3000cm!!!!!
