Group Radii of Tomatoes (centimeters)

Mathematics
1 answer:
denis23 [38]3 years ago
5 0

Answer: Option 'B' is correct.

Step-by-step explanation:

since we have given that

Group radii of fertilized tomatoes is given by

0.8, 1.1, 0.9, 0.8, 1.0, 1.2, 0.9, 1.1, 1.0, 1.2

Group radii of unfertilized tomatoes is given by

1.4, 1.6, 1.3, 1.5, 1.1, 1.5, 1.6, 1.2

So, we will first find the mean of both the group i.e.

Mean radii of fertilized tomatoes is given by

=\frac{0.8+1.1+0.9+0.8+1.0+1.2+0.9+1.1+1.0+1.2}{10}\\\\=1

Similarly,

Mean radii of unfertilized tomatoes is given by

\frac{1.4+1.6+1.3+1.5+1.1+1.5+1.6+1.2}{8}\\\\=\frac{11.2}{8}\\\\=1.4

So, the difference between the mean radii of fertilized and unfertilized tomatoes will be

1.4-1=0.4\ cm

Hence, Option 'B' is correct.

A researcher studying public opinion of proposed Social Security changes obtains a simple random sample of 35 adult Americans an
Liula [17]

Answer:

Adult required in the case of “a” 28 and in the case of “b” the adult requirement is 19.

Step-by-step explanation:

(a) The percentage of adult that support the change is 20 percent.

Now calculate the number of adult required.

Given p = 0.20

Use the below condition:

np(1 – p) \geq 10 \\n \times 0.20 (1 – 0.20) = 10 \\n = 63 round off

Since 35 adults are already there so required adults are 63 -35 = 28

(b) The percentage of adult that support the change is 25 percent.

Now calculate the number of adult required.

Given p = 0.25

Use the below condition:

np(1 – p) \geq 10 \\n \times 0.25 (1 – 0.25) = 10 \\n = 54 (round off)

Since 35 adults are already there so required adults are 54 -35 = 19 .

What is the solution set of 2x(x - 1) = 3?
garik1379 [7]

First you must distribute the 2x to the numbers inside the parentheses

(2x * x) + (2x * -1) = 3

2x^{2} - 2x = 3

To make this a quadratic equation you can solve bring the 3 over to the left side of the equation by subtracting it to both sides

2x^{2} - 2x - 3 = 0

Use the quadratic equation to solve this (image of the quadratic equation is below)

Remember that quadratic functions are set up like so:

ax^{2} +bx +c = 0

That means that in this equation...

a = 2

b = -2

c = -3

^^^Plug these numbers into the quadratic equation and solve...

\frac{2+/-\sqrt{(-2)^{2}-4(2)(-3)}}{2(2)}

\frac{2 +/-\sqrt{4+24}}{4}

\frac{2+/-\sqrt{28} }{4}

\frac{2+/-2\sqrt{7} }{4}

\frac{1+/-\sqrt{7} }{2}

Keep in mind that +/- is ±

\frac{1+\sqrt{7} }{2}

\frac{1-\sqrt{7} }{2}

^^^Exact answers
