I need this answered in ONE minute

Answer:

$x^4 + 4x^3 + 6x^2 + 7x + 2$

Step-by-step explanation:

We are asked to multiply the given polynomials.

$(x^ 2 + 3x + 1) \times (x^2 + x + 2)$

Multiply each term of the first polynomial to each term of the second polynomial.

$x^ 2 \times (x^2 + x + 2) = x^4 + x^3 + 2x^2$

$3x \times (x^2 + x + 2) = 3x^3 + 3x^2 + 6x$

$1 \times (x^2 + x + 2) = x^2 + x + 2$

Add the results

$(x^4 + x^3 + 2x^2) + (3x^3 + 3x^2 + 6x) + ( x^2 + x + 2)$

Combine the like terms

$x^4 + 4x^3 + 6x^2 + 7x + 2$

The answer is written in descending powers of x.

To decrease an amount by 4% what single multiplier would u use ??

serg [7]

If you decrease something by 4 percent,

you are keeping (100% - 4%) or 96% of the original

so multiply by the original amount by 96 percent or .96

If you have 100 pennies, and you give 4 away ( 4 percent decrease), you still have 96 pennies. You are keeping 96 percent of what you started with. This works no matter how much you start with.

Example:

you have 40 dollars

4% decrease

40 * .04 = 1.6 take this away

40 - 1.6 = 38.4 left

you keep 96 percent

40 * .96 = 38.4 left

A distributor of personal computers has five locations in a city. In the year's first quarter, the sales in units were: Location

Deffense [45]

Answer:

The correct option is (c) 13.277.

Step-by-step explanation:

The observed data is:

Location Observed sales (units)

Northside 70

Pleasant Township 75

Southwick 70

I-90 50

Venice Avenue 35

TOTAL 300

The test statistic for the Goodness of fit test is:

$\chi^{2}=\sum\frac{(Observed-Expected)^{2}}{Expected}$

For k independent samples this test statistic follows a Chi-square distribution with degrees of freedom (k - 1).

The sample size in this case is, k = 5.

The degrees of freedom is, (k - 1) = 4.

The level of significance is, α = 0.01.

The critical value of the test is:

$\chi^{2}_{\alpha ,k-1}=\chi^{2}_{0.01,4}=13.277$

**Use the Chi-square table.

Thus, the critical value is 13.277.
