Mathematics
1 answer:
Karo-lina-s [1.5K]2 years ago
6 0

Answer:

Step-by-step explanation:

Volume = length * width * height

= (x + 1) *x *(3x + 5)    

Multiply (x +1) and x

= (x*x + x*1) * (3x +5)

= ( x² + x) * (3x + 5)          

= x²*(3x +5 ) + x(3x +5)

=x²*3x + x²*5 + x*3x + x*5

= 3x³ + 5x² + 3x² + 5x

= 3x³ + 8x² + 5x

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.

Graph the point (4, -1) on the coordinate plane below.<br>​
dimulka [17.4K]
See the blue dot in the attached image.



First, find the x value on the coordinate plane. The x value is the first number in the point coordinates, so in this case, it is 4. Move to the right 4. (If it was negative, you would move to the left.)

Then, find the y value, which is the second number of the coordinates. In this case, it is -1, so move down 1. (If it was positive, you’d move up.)

Now, mark this point. This is (4, -1).

otez555 [7]

Answer:

- 35  

Step-by-step explanation:

2(x - 7) = 3(x+7)

2x - 14 = 3x + 21

- 21 - 14 = 3x - 2x

x = - 35  

Rechecking :

2(-35 - 7) = 3 (-35 +7)

- 84 = - 84

I hope im right!!!
