Solve for x. (6x - 7) (10x - 47)​

Answer:

8.30

Step-by-step explanation:

Lee mailed 3 packages

If he paid 1.70 for 1 package and 3.60 for 2 package

= 3.60×2 + 1.70

= 7.2+1.70

= 8.9

If Lee paid 3.60 for 1 package and 1.70 for 2 packages

= 3.60 + 1.70(2)

= 3.60 + 3.4

= 7

Hence the price paid to mail the thee packages is 8.30 because it falls in between 7 and 8.9

Answer: a. $8.30

Step-by-step explanation:

Highest paid was $3.60 and lowest paid was $1.70. There is a middle package that cost less than $3.60 and more than $1.70.

= 3.6 + 1.7

= $5.30

This rules out option c because we have not added the price of the third package and it is already higher than option c.

Add the maximum twice:

= 3.6 + 3.6 + 1.7

= $8.90

If the second package was assumed to have the same cost as the highest paid, the total would still be less than options b and d which makes them both wrong.

Option a is the most feasible answer.

Step-by-step explanation:

Answer: C. the test does not provide convincing evidence that the percent is less than 2%, but the actual percent is 1%

Step-by-step explanation:

A Type II error occurs if a false null hypothesis is not rejected. In this case, the new assembly line does reduce the percent of defective items, but the test fails to detect it.

You can use the definition of type II error to identify what option describes a Type II error.

The option that describes a type II error that could result from the test is:

Option  C) The test does not provide convincing evidence that the percent is less than 2% (ie we cannot reject null hypothesis and thus accept it), but the actual percent is 1% (ie the accepted null hypothesis was wrong in reality, thus, causing type II error)

Firstly the whole story starts from hypotheses. The null hypothesis is tried to reject and we try to accept the alternate hypothesis.

The negative is just like the doctor's test getting negative means no disease. Similarly, if we conclude null hypothesis negative means it is accepted. If it is accepted wrongly means the negative test result was false, thus called false negative. This error is called type II error.

Since the specified null hypothesis is [tex]H_0[/tex] = The percent of defective parts is at least 2%.

Thus, according to the aforesaid definition of type II error, we get:
Acceptance of null hypothesis since the test doesn't provide enough evidence for alternate hypothesis to be true or that the test doesn't provide enough evidence that the percent is less than 2% but the actual percent is less than 2%

Thus, Option C) The test does not provide convincing evidence that the percent is less than 2%(ie we cannot reject null hypothesis and thus accept it), but the actual percent is 1%(ie the accepted null hypothesis was wrong in reality, thus, causing type II error)

Point of intersection of equations is (1 , 6)

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.

Given equations

y = 3x + 3    ---------(1)

y = x + 5      ---------(2)

Subtracting equation 2 from equation 1.

y - y = 3x + 3 - (x + 5)

0 = 3x + 3 - x - 5

0 = 2x - 2

x = 1

Putting value of x in equation 2

y = 1 + 5

y = 6

Intersection point,

(x , y) = (1 , 6)

Hence, (1 , 6) is the point of intersection of given equations.

To find:-

[tex]\bigstar{\boxed{\pmb{equation~of~the~line}}[/tex]

Solution:-

Notice that we're asked to write the line's equation in slope-intercept form.

Slope-intercept looks  like so:

[tex]\bigstar{\boxed{y=mx+b}[/tex]

where m -> slope & b -> y-intercept

Oh wow, it's really easy now, because we should just plug in the values:-

Answer:

All polynomial functions of positive, odd order have at least one zero (this follows from the fundamental theorem of algebra), while polynomial functions of positive, even order may not have a zero (for example x4+1 x 4 + 1 has no real zero, although it does have complex ones).

Answer:

x=50°, x=70°

Step-by-step explanation:

for the first one, we will find the interior angle by using the exterior angle given

180-120=60°

to find x,

60°+ x + x+20=180°

80°+2x=180°

2x=100°

x=50°

for the second one, we will also find the interior angle by using the exterior angle given

180-200=20°

to find x,

20°+ x + x+20=180°

40°+2x=180°

2x=180°-40°

2x=140°

x=70°

Answer:

w = 2 + 8x

Step-by-step explanation:

this is the only equation where, after plugging in hours and wages, the values are correct

The equation where, after plugging in hours and wages, the values are correct would be; w = 2 + 8x

An equation is an expression that shows the relationship between two or more numbers and variables.

We have been given that John delivers newspapers every morning in his neighborhood.

John gets paid based on the number of hours x, that he works.

Thus the only equation where, after plugging in hours and wages, the values are correct would be;

w = 2 + 8x

Substituting x = 1

w = 2 + 8(1)

w = 10

Hence, this equation is correct.
