The factors of  50a³  are  1,  2,  5,  10,  25,  50,
   and their products with a, a² and a³ .

The factors of  10a²  are  1,  2,  5,  10,
    and their products with 'a' and a² .

Their common factors are  1, 2, 5, 10,
       and their products with 'a' and a².

Their greatest common factor is  10a² .

(Another way to spot it, easily, is to remember this helpful factoid:

                 If the smaller number is a factor of the larger number,
                 then the smaller number is their greatest common factor.

Using the greatest common factor, then . . .

           50a³ + 10a²  =     10a²(5a + 1) .

coldgirl [10]

Answer:

Note: The full question is attached as picture below

a) Hо : p = 0.71

Ha : p ≠ 0.71

<em>p </em>= x / n

<em>p </em>= 91/110

<em>p </em>= 0.83.

1 - Pо = 1 - 0.71 = 0.29.

b) Test statistic = z

= <em>p </em>- Pо / [√Pо * (1 - Pо ) / n]

= 0.83 - 0.71 / [√(0.71 * 0.29) / 110]

= 0.12 / 0.043265

= 2.77360453

Test statistic = 2.77

c) P-value

P(z > 2.77) = 2 * [1 - P(z < 2.77)] = 2 * 0.0028

P-value = 0.0056

∝ = 0.01

P-value < ∝

Reject the null hypothesis.  There is sufficient evidence to support the researchers claim at the 1% significance level.

There are two spinners. Each spinner has 10 equal sectors labeled with the numbers 1 through 10.
Reika [66]

Answer: Second option is correct.

Step-by-step explanation:

Since we have two spinners,

Each spinner has 10 equal sectors labeled with the numbers from 1 to 10.

Primes numbers from 1 to 10 is given by

\{2,3,5,7\}

So, number of outcomes shows a  primes number from 1 to 10 = 4

Similarly ,

Composite numbers from 1 to 10 is given by

\{4,6,8,9,10\}

So, number of outcomes shows a composite number from 1 to 10 =5

∴ Total outcomes show a prime number on the first spinner and a composite number on the second spinner is given by

4\times 5=20\\

Thus, Second option is correct.
