Answer:

16x³ + 9x² + 9x + 13

Step-by-step explanation:

Given

6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9

Sum the 2 expressions by adding like terms, that is

= (6x³ + 10x³) + (8x² + x²) + (- 2x + 11x) + (4 + 9)

= 16x³ + 9x² + 9x + 13

To estimate the percentage of defects in a recent manufacturing​ batch, a quality control manager at General Foods selects every
Hoochie [10]

Answer:

B. Systematic

Step-by-step explanation:

<em>Since Quality Control Manager is selecting every 10th soup. This type of Sampling Method is called Systematic Sampling.</em>

Further,

If the whole population is divided into many groups(strata) such that between the group units are heterogeneous and within the group units are homogeneous then units are randomly selected from these groups. This type of sampling is called Stratified Sampling.

If the sampling is done by any criteria then this type of sampling method is called Systematic Sampling. Like observer is taken every 5th unit as a sample.

If the samples from the population are chosen randomly, where each and every unit has an equal chance of selection in a sample. This type of sampling is called Simple Random Sampling.

In Cluster Sampling the population is distributed into a distinct group (clusters) and one or more groups (clusters) are chosen as a sample then it is Cluster Sampling.

If the observers collect the sample as his\her convenience, then this type of sampling method is called Convenience Sampling.

PLEASEE HELPP!!!!

y = - \frac{1}{4} x + \frac{15}{2}

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = 4x + 5 is in this form with slope m - 4

Given the slope of a line m, then the slope (m_{2}) of a line perpendicular to it is

m_{2} = - (1 / m ) = - \frac{1}{4}

y = - \frac{1}{4} x + c is the partial equation of the perpendicular line

to find c, substitute ( 2, 7 ) into the partial equation

7 = - \frac{1}{2} + c ⇒ c = \frac{15}{2}

y = - \frac{1}{4} x + \frac{15}{2} ← equation of perp. line

Definition: An outcome in a probability experiment.
snow_tiger [21]

Answer: possible result of an experiment

Step-by-step explanation: in probability theory, An outcome is a possible result of an experiment. Each possible outcomes of a particular experiment is unique, and different outcomes are mutually exclusive (Only one outcome Will occur on each trial of the experiment). All of the possible outcomes of an experiment formed elements of a sample space.

Maya is taking her friends to a concert. Each ticket costs
ddd [48]

Answer:

C. 25x+12y+4≤ 130

Step-by-step explanation:

Each ticket cost $25, so x would be the number of tickets she has to buy.

25x

Each T-shirt cost $12, so y would be the number of T-shirts she can buy.

12y

And since there is an service fee for the entree purchase, that's another $4.

+4

The cost of everything has to be less than $130, so the equation would be:

25x+12y+4≤ 130
