A botanist has developed a new hybrid cotton plant that can withstand insects better than other cotton plants. However, there is

some concern about the germination of seeds from the new plant. To estimate the probability that a seed from the new plant will germinate, a random sample of 3000 seeds was planted in warm, moist soil. Of these seeds, 2200 germinated. (a) Use relative frequencies to estimate the probability that a seed will germinate. What is your estimate? (Enter your answer to 3 decimal places.)

Answer:

n = 3000 seeds planted in the farm

From these 3000 we know that only 2200 germinated

In order to determine the probability that a seed will germinate we can use the definition of probability given by:

p =\frac{Possible}{Total}

From this definition we need to divide the possible cases by the total cases and for this case if we replace we got:

p =\frac{2200}{3000}= 0.733

So then the probability that the seed will germinate is 0.733 from the sample data obtained

Step-by-step explanation:

For this case we know that the sample size is:

n = 3000 seeds planted in the farm

From these 3000 we know that only 2200 germinated

In order to determine the probability that a seed will germinate we can use the definition of probability given by:

p =\frac{Possible}{Total}

From this definition we need to divide the possible cases by the total cases and for this case if we replace we got:

p =\frac{2200}{3000}= 0.733

So then the probability that the seed will germinate is 0.733 from the sample data obtained

Find the volume of the pet carrier shown at the right
cluponka [151]

Answer:

  Volume of the pet carrier   =2702.5 cubic inches

Step-by-step explanation:

The Pet carrier in the image is in the shape of a cuboid

The volume of a cuboid can be found by the formula

         volume of cuboid= Length*Breadth*Height

Given:

Length = 20 inches,                          Breadth=11\frac{3}{4} =\frac{(11*4)+3}{4}=\frac{47}{4} inches,                          

 

Height=11\frac{1}{2}=\frac{23}{2} inches

Volume of the pet carrier:

                                          =20*\frac{47}{4}* \frac{23}{2}\\\\= 5*47*\frac{23}{2} \\\\=5*47*11.5\\

                                         =2702.5 cubic inches

Volume of the pet carrier   =2702.5 cubic inches

Ten times the square of a non‐zero number is equal to seventy times the number. What is the number?
Nikolay [14]
The original number is 7 i think.
10(x^2) = 70x
10x^2 - 70x = 0
x^2 -7x =0
Δ= b^2 -4ac
where c doesnt exist=0
Δ= 49
-b ± √Δ /2a
7 ± √49 /2
7±7/2
x is either 14/2= 7
or 1/2, which doesnt work.

Lets see:
10(7^2) = 70•7
10•49 = 490
and that is right.

i hope my logic is correct.

Question 5 (12 points)
Dima020 [189]

Answer:

see attached for diagram

a) √13

b) √29

c) 4

Step-by-step explanation:

Equation of the circle:  (x + 1)^2 + (y - 3)^2 = 16

⇒ center = (-1, 3)

⇒ radius = √16 = 4

Distance between 2 points formula:

\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

a)  let (-1, 3) = (x_1,y_1)

    let (2, 1) = (x_2, y_2)

 \implies \sqrt{(2+1)^2+(1-3)^2} =\sqrt{13}

b)  let (-1, 3) = (x_1,y_1)

    let (4, 1) = (x_2, y_2)

\implies \sqrt{(4+1)^2+(1-3)^2} =\sqrt{29}

c)  let (-1, 3) = (x_1,y_1)

    let (3, 3) = (x_2, y_2)

\implies \sqrt{(3+1)^2+(3-3)^2} =4

Will the product be more or less than 9 8/9
solniwko [45]
It would be less because when you multiply something by 1/2 you are basically dividing it by 2, finding half. So when you multiply 9 8/9 by 1/2 your product would be less than 9 8/9
