Answer:

No solution

Step-by-step explanation

7x+10=7x+10

Step 1: Subtract 7x from both sides.

7x+10−7x=7x+10−7x

10=10

Step 2: Subtract 10 from both sides.

10−10=0

See attached a detailed annotation of the LP formulation

let is describe the problem bellow.

An electronics company has a contract to deliver  21,475 radios within

the next four weeks. The client is willing to pay

$20 for each radio delivered by the end of week 1

$18 for each radio delivered by the end of week 2

$16 for each radio delivered by the end of week 3

$14 for each radio delivered by the end of week 4

Each worker can assemble 50 radios/wk.

Size of present workforce = 40.

Any experienced worker can be taken off the assembly line to instruct a class

of three trainees; after one week of instruction, each of the trainees can

either proceed to the assembly line or instruct additional new classes.

Weekly wages for experienced workers: $200

Weekly wages for trainees: $100

Production costs, excluding wages: $5/radio.

Step-by-step explanation:

3[a(4b - c)] for a = 2, b =3, and c = 2.8.

-3[a(4b - c)]

-3[2(43 - 2.8)]

You first have to do the Equation that is in brackets and slowly make your way up.

and you will find that ur awnser is = 241.2

Hope it helped you!

The value of the expression 3[a(4b - c)]  for a = 2, b =3, and c = 2.8

will be;

⇒ 55.2

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 3[a(4b - c)]

And, The values are a = 2, b =3, and c = 2.8.

Now,

Find the value of expression by substitute the values a = 2, b =3, and

c = 2.8. as;

The expression is,

⇒ 3[a(4b - c)]

⇒ 3 [ 2 (4 × 3 - 2.8)]

⇒ 3 [ 2 (12 - 2.8) ]

⇒ 3 [ 2 × 9.2 ]

⇒ 3 × 18.4

⇒ 55.2

Therefore, The value of the expression 3[a(4b - c)]  for a = 2, b =3, and

c = 2.8 will be;

⇒ 55.2

Answer:

Option A: Multicollinearity

Step-by-step explanation:

Multicollinearity is said to be present when there are high correlations between two or more independent variables called predictor variables. In simple terms, Multicollinearity refers to when the independent variables present in a regression model are correlated.

Tolerance is simply used to detect Multicollinearity.

Rank is basically the model in which the ranks of the dependent variable are said to have regressed on a set of characteristics in the experiment known as covariates.

Confidence level is the percentage of all possible samples that we can expect to be included within the true population parameter.

Looking at all the definitions, the one that fits with the statement in the question is Multicollinearity.

Answer:

Step-by-step explanation:

The previous solar eclipse occured on March 7 , 1970 .

saros cycle has duration of 18 years , 11 + 1/3 days

So the earth goes 1 / 3 of its daily rotation beyond its previous location in the next solar eclipse on the earth . In order that we get solar eclipse on the same point on the earth , we shall have to wait for third solar eclipse

So total period of wait = 18 x 3 years + 11 x 3 + 1 = 54 years and 34 days

Date of next solar eclipse on the same spot = 1970 + 54 = 2024

7 th March + 34 days = April 10

likely date = April 10 , 2024 .

So we know the formula to calculate the area of the circular sector:

S=(r^2*π*a)/306°=

(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.

Step-by-step explanation:

r - radius of the circle

a - corner of the circular sector

S - surface

Answer:

b. a statistic.

Step-by-step explanation:

the value 1670 is regarded as a statistic. this is because it is a representation of the value of a sample. from the question we get that destructive testing is being done this shows is that what we have here is a sample.

the mean force 1670 is not a parameter, a point estimate, a confidence interval or interval estimate. therefore option b is the answer.
