Answer:

D. highly unlikely

Step-by-step explanation:

There are 20 total outcomes.

The number 1 is only 1 outcome out of 20 outcomes.

The probability of it landing on 1 is 1/20.

0 - impossible

0.1 - highly unlikely

0.25 - unlikely

0.5 - even

0.75 - likely

0.9 - highly likely

1 - certain

1/20 = 0.05

0.05 is highly unlikely.

Factor x^4-5x^2+4 show your work

ch4aika [34]

Answer:

$(x+2)(x-2)(x+1)(x-1)$

Step-by-step explanation:

STEP 1: Rewrite $x^{4}$ as $(x^2)^2$ .

$(x^2)^2-5x^2+4$

STEP 2: Let $u=x^{2}$ . Substitute $u$ for all occurrences of $x^{2}$ .

$u^2-5u+4$

STEP 3: Factor $u^2-5u+4$ using the AC method.

$(u-4)(u-1)$

STEP 4: Replace all occurrences of $u$ with $x^2$ .

$(x^{2} -4)(x^{2} -1)$

STEP 5: Rewrite $4$ as $2^{2}$ .

$(x^{2}-2^{2})(x^{2}-1)$

STEP 6: Since both terms are perfect squares, factor using the difference of squares formula, $a^2-b^2=(a+b)(a-b)$ where $a=x$ and $b=2$ .

$(x+2)(x-2)(x^{2}-1)$

STEP 7: Rewrite $1$ as $1^{2}$ .

$(x+2)(x-2)(x^2-1^2)$

STEP 8: Factor.

$(x+2)(x-2)(x+1)(x-1)$

Hi guys, can you please help me with this?

Digiron [165]

Answer:

see explanation

Step-by-step explanation:

Expand the right side and then compare like terms with the left side.

(q + 2 $\sqrt{3}$ )²

= q² + 4q $\sqrt{3}$ + 12

= q² + 12 + 4q $\sqrt{3}$

Compare like terms with 28 + p $\sqrt{3}$

Comparing the $\sqrt{3}$ terms gives

p = 4q

and comparing the constant terms gives

q² + 12 = 28 ( subtract 12 from both sides )

q² = 16 ( take the square root of both sides )

q = ± $\sqrt{16}$ = ± 4

Hence

p = 4q = 4 × ± 4 = ± 16

Han recorded the number of pages that he read each day for five days. the dot plot shows his data. pages the mean, or average, f

Paul [167]

If the mean of the data set is 32.6. Then the number of pages he read in 5 days is 163.

Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.

Han recorded the number of pages that he read each day for five days.

If the mean of the data set is 32.6 pages. Then the total number of the pages he read till now, will be

Let the total number of the pages be x. Then we have

$\rm \dfrac{x}{5} = 32.6\\\\x \ = 5 \times 32.6 \\\\x \ = 163$

More about the mean link is given below.
