Answer:

3 x 5 x 13

step-by-step explanation:

find the factors of 195 that are prime numbers.

48 cups

step-by-step explanation:

the first 2 cups of raisins goes into 12 cups of trail mix.

the next ones are as follows:

4 cups of raisins for 24 cups of trail mix

6 cups of raisins for 36 cups of trail mix

8 cups of raisins for 48 cups of trail mix

they both double each time a new bathc is made.

for this case we have that the area of the figure is given by the area of a rectangle plus the area of a triangle.

the area of a rectangle is given by:

a = a * b

where a and b are the sides of the rectangle.

according to the figure we have:

a = 13 \ cm\\b = 9 \ cm

so, the area of the rectangle is:

a = 13 * 9\\a = 117 \ cm ^ 2

on the other hand, the area of a triangle is given by:

a = \frac {1} {2} b * h

where b is the base of the triangle and h the height. according to the figure we have:

b = 13-8 = 5 \ cm\\h = 11 \ cm

substituting:

a = \frac {1} {2} 5 * 11\\a = 27.5 \ cm ^ 2

adding up we have the total area is:

a_ {t} = 117 \ cm ^ 2 + 27.5 \ cm ^ 2\\a_ {t} = 144.5 \ cm ^ 2

option b

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2

 

length = 236 yards

width = 144 yards

step-by-step explanation:

let the width be x

then length = 92 more than x = 92+x

formula for perimeter of rectangle   = 2 [ length + width]

     therefore

                 760   =     2 [   92+x + x ]

                 760 = 2 ( 92+2x )

               760 = 184 + 4x

           4x = 760 - 184

           4x = 576

             x= \frac{576}{4} =

             x = 144

so width = 144 yards

length = 144+92 = 236 yards

The graph below represents a polynomial.
AleksAgata [21]

Answer:

C

Step-by-step explanation:

The polynomial on the graph has zeros or x-intercepts at x = -3, 0, 2, 4. These come from the factors x (x+3)(x-2)(x-4). Notice at 4 it doesn't cross but just touches. This means it has a degree of 2. So the factors are x(x+3)(x-2)(x-4)^2. This matches to C.

In general, the probability that a blood donor has Type A blood is 0.40.Consider 8 randomly chosen blood donors, what is the pro
postnew [5]

Answer:

The probability that more than half of them have Type A blood in the sample of 8 randomly chosen donors is P(X>4)=0.1738.

Step-by-step explanation:

This can be modeled as a binomial random variable with n=8 and p=0.4.

The probability that k individuals in the sample have Type A blood can be calculated as:

P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}\\\\\\P(x=k) = \dbinom{8}{k} 0.4^{k} 0.6^{8-k}\\\\\\

Then, we can calculate the probability that more than 8/2=4 have Type A blood as:

P(X>4)=P(X=5)+P(X=6)+P(X=7)+P(X=8)\\\\\\P(x=5) = \dbinom{8}{5} p^{5}(1-p)^{3}=56*0.0102*0.216=0.1239\\\\\\P(x=6) = \dbinom{8}{6} p^{6}(1-p)^{2}=28*0.0041*0.36=0.0413\\\\\\P(x=7) = \dbinom{8}{7} p^{7}(1-p)^{1}=8*0.0016*0.6=0.0079\\\\\\P(x=8) = \dbinom{8}{8} p^{8}(1-p)^{0}=1*0.0007*1=0.0007\\\\\\\\P(X>4)=0.1239+0.0413+0.0079+0.0007=0.1738

The weight of people in a small town in missouri is known to be normally distributed with a mean of 154 pounds and a standard de
ad-work [718]
If a random sample of 20 persons weighed 3,460, the sample mean x-bar would be 3460/20 = 173 pounds.
The z-score for 173 pounds is given by:
z=\frac{173-154}{29}=0.655
Referring to a standard normal distribution table, and using z = 0.66, we find:
P(\bar x\ \textless \ 173)=0.7454
Therefore
P(\bar x\ \textgreater \ 173)=1-0.7454=0.2546
The answer is: 0.2546

Pls explain your work!
mylen [45]

Answer:

find total volume to find what amount is 20%

hack, is put the 20% in alreadyy to find 20% volume

20%=1/5

so

vcone=1/3(hpir^2)

times thath by 1/5

vcone=1/15(hpir^2)

d/2=r

given

4.8=d

4.8/2=d/2=r=2.4

10=h

V=1/15(10pi2.4^2)

V=1/15(10pi5.76)

V=1/15(57.6pi)

V=3.84pi

V=12.0637 cubic inches=20% of vase

0.5 cubc inches per min

0.5 times t=12.0637

divide both sides by 0.5

t=24.1237

about 24 minutes
