Answer: 48.4 cm^2

Step-by-step explanation:

l*h=40 cm^2

l*(l+3)=40 cm^2

l*(l+3)=5*8

so l=5, h=8

when l=5+10/100 *5=5+1/2=5.5 cm

h=8+10/100*8=8+8/10=8.8 cm

Area now is 5.5*8.8=48.4 cm^2

Suppose the probability that a randomly selected man, aged 55-59, will die of cancer during the course of the year is startfra

Romashka-Z-Leto [24]

The probability that a randomly selected man dies of cancer during the course of the year = $\frac{300}{100000}= \frac{3}{1000}=0.003$

The probability that a randomly selected man does not die of cancer during the course of the year = $1-0.003=0.997$

The probability that atleast one man of this age dies of cancer is the complement of the probability that no man dies of cancer. In equation form we can write:

Probability that atleast one man of this age dies of cancer = 1 - No man at this age dies of cancer

The probability that no man dies of cancer out of 1000 selected men = $(0.997)^{1000}=0.04956$ , rounded of to 5 decimal places

Thus the probability that atleast one man at this age dies of cancer = 1 - 0.04956 = 0.95044

Marcus is buying 10 gift bags for his birthday party. He will choose items to put in the bags and then pay an additional charge

adoni [48]

10*0.75 + 10*x $\leq$ 50
This is how our inequality looks where x represents items cost per bag.

10*x $\leq$ 42.5

x $\leq$ 4.25.

Marcus can spend $4.25 at most per bag.
The money he spent on buying bags we can calculate right away because we know how much one bag costs and how many bags he bought.

How to find the discriminant of

Sonbull [250]

the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0

13x^2-16x = x^2 -x

we need to get in it the standard form

subtract x^2 from each side

12x^2 -16x = -x

add x to each side

12x^2 -15x = 0

12x^2 -15x -0 =0

a=12 b=-15 c=0

b^2 -4ac

the discriminant = b^2

b^2 = (-15)2 = 225
