Find the product (x-y)(6x+4y)

Mazyrski [523]

The product means you multiply, so:
-y × 6x = -6xy
-y × 4y = -4y²

x × 6x = 6x²
x × 4y = 4xy

= -2xy - 4y² + 6x

I hope this helps!

Which set of rational numbers is arranged from least to greatest? 1 over 5, −1.4, negative 1 over 2, 3 3, negative 1 over 2, −1.

Mars2501 [29]

Answer:

Option 4 - $-1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3$

Step-by-step explanation:

To find : Which set of rational numbers is arranged from least to greatest?

Solution :

The set of rational numbers are

$3,\ \frac{1}{5},\ -1.4,\ -\frac{1}{2}$

Writing all number in one form,

$\frac{1}{5}=0.2$

$-\frac{1}{2}=-0.5$

Now, -1.4<-0.5<0.2<3

From least to greatest the set of natural numbers are

$-1.4$

So, $-1.4,\ -\frac{1}{2},\ \frac{1}{5},\ 3$

Therefore, option 4 is correct.

The average hourly wage of computer programmers with 2 years of experience has been $21.80.Because of high demand for computer p

svp [43]

Answer:

d. H0: μ <= 21.80 Ha: μ > 21.80

Step-by-step explanation:

We set the null hypothesis as what is already given . We are already informed that the average wage is equal to μ <= 21.80 against the claim that is required. It is required to test whether the average wage of the computer programmers is greater than μ > 21.80

So option d is the best answer.

Hypotheses testing is done using an observation and a claim. The observation is set as a null hypothesis and claim is set as an alternative hypothesis. The null and alternative hypotheses must be chosen wisely to get the correct results.

The critical region is dependent on the claim set.

Kellogg's produced 715000 boxes of cornflakes this year. This was 110% of annual production last year. What was last year's annu

Charra [1.4K]

Let last year product be x boxes.

110% of x means $\displaystyle{ \frac{110}{100}\cdot x$ .

Thus, we solve the equation:

$\displaystyle{ \frac{110}{100}\cdot x=715,000$ .

Multiplying both sides by $\displaystyle{ \frac{100}{110}$ , we have:

$\displaystyle{ x=715,000 \cdot \frac{100}{110}=650,000$ .

Answer: Last <span>year's annual production was 650,000 boxes.</span>
