A spinner is evenly divided into eight sections: three are red, three are white and two are green. If the spinner is spun twice,

Stolb23 [73]

Answer:

11/32

Step-by-step explanation:

Given that:

Red section (R) = 3 ; white section (W) = 3 ; green section (G) = 2

Total Number of sections = 8

Probability of getting the same color on two spins :

Probability = (required outcome / Total possible outcomes)

Either P(RR) or P(WW) or P(GG)

(3/8 * 3/8) + (3/8 * 3/8) + (2/8 * 2/8)

9/64 + 9/64 + 4/64

(9 + 9 + 4) / 64

22 / 64

= 11/32

Management at a home improvement store randomly selected 45 customers and observed their shopping habits. They recorded the numb

Bas_tet [7]

Answer:

c. number of items - discrete; total time - continuous

Step-by-step explanation:

The question is incomplete due to the lack of the following options:

to. number of items - continuous; total time - discrete

b. number of items - continuous; total time - continuous

c. number of items - discrete; total time - continuous

d. number of items - discrete; total time - discrete

Knowing this, the type of variables recorded by managers of the home improvement store are,

c. number of items - discrete; total time - continuous

Discrete variables are those that are well defined and in the finite set of values and continuous variables are variables that can take a value between any of the other two values.

Determine the solution set of (2x - 1)2 - 100 = 0.

mylen [45]

Distribute: 4x - 2 - 100 = 0

add 102 to both sides: 4x = 102

Divide both sides by 4: x = 25.5

Expressed as a product of its prime factors in index form, a number N is

Elena-2011 [213]

<u>ANSWER</u>

$5N^2=3^{2} \times 5^{5} \times x^{6}$

<u>EXPLANATION</u>

$N=3\times5^2 \times x^3$ .

$5N^2=5(3\times5^2 \times x^3)^2$

Recall this property of exponents;

$(a^m)^2=a^{m} \times a^m$

So our product becomes;

$5N^2=5(3\times5^2 \times x^3) \times (3\times5^2 \times x^3)$

$5N^2=5\times 3\times 3 \times 5^2 \times 5^2 \times x^3 \times x^3$

$5N^2=3\times 3\times 5 \times 5^2 \times 5^2 \times x^3 \times x^3$

Recall this law of exponents:

$a^m \times a^n =a ^{m+n}$

$5N^2=3^{1+1} \times 5^{1+2+2} \times x^{3+3}$

$5N^2=3^{2} \times 5^{5} \times x^{6}$
