Step-by-step explanation:

Answer:

3.949

Step-by-step explanation:

We can use the formula to find the error bound:

EBM=(zα/2)(σn/√)

We know that σ=7 and n=17. We are also given that the confidence level (CL) is 98%, or 0.98. So, we can calculate alpha (α).

α=1−CL

=1−0.98

=0.02

Since α=0.02, we know that

α2=0.022=0.01

The value of z0.01 is 2.326. Now we can substitute the values into the formula to find the error bound.

EBM=(zα/2)(σ/√n)

=(2.326)(7/√17)

≈(2.326)(1.698)

≈3.949

So, the error bound (EBM) is 3.949.

Step-by-step explanation:

Let's write the equation with formula:- Where, x1 is -1 and y1 is 4 and m is 3Thus, The correct choice is option C.

Step-by-step explanation:

Equation of line formula=> y=mx+c

Let take point (-1,4) as (x, y) and slope m=3

4= 3(-1) +c

4= -3+c

4+3=c

7=c

Therefore by using equation of line formula we get

y= mx+c [m=3 , c=7]

y=3x+7

Answer: y=8x-7 just took the quiz hope that helps

The other equation could be y = 8x - 7

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

to determine the other equation:

The first equation is given as:

y = 8x + 7

For the system of equation to have no solution, then the equations in the system would have different constant values.

Take for instance:

y = 8x + b

Where:

b is a constant not equal to 7

From the options, we have:

y = 8x - 7

Notice that -7 and 7 are not the same

Hence, the other equation could be y = 8x - 7

I took the test on Edge

Using proportions, it is found that they had traveled 245 miles when Jack fell asleep.

A proportion is a fraction of a total amount.

Jack slept through the last 65% of the trip, hence he fell asleep when 100 - 65 = 35% of the 700 mile trip had been traveled, so:

0.35 x 700 = 245.

They had traveled 245 miles when Jack fell asleep.

Answer:

191.25 mm

Step-by-step explanation:

area of triangle is 1/2 b*h

1/2 (7.5*15) = 56.25

area of rectangle is b*h

15*9 = 135

56.25+135 = 191.25

Answer:

Answer:

49 units squared

Step-by-step explanation:

The area of a trapezoid is calculated with the following formula:

(a+b)*1/2*h (a: base, b: base, h: height)

(3+11) * 1/2 * 7 = 49 the area is stated in square units so the answer is 49^2

Answer:

  34.5 square meters

Step-by-step explanation:

We assume you want to find the area of the shaded region. (The actual question is not visible here.)

The area of the triangle (including the rectangle) is given by the formula ...

  A = 1/2bh

The figure shows the base of the triangle is 11 m, and the height is 1+5+3 = 9 m. So, the triangle area is ...

  A = (1/2)(11 m)(9 m) = 49.5 m^2

The rectangle area is the product of its length and width:

  A = LW

The figure shows the rectangle is 5 m high and 3 m wide, so its area is ...

  A = (5 m)(3 m) = 15 m^2

The shaded area is the difference between the triangle area and the rectangle area:

  shaded area = 49.5 m^2 - 15 m^2 = 34.5 m^2

The shaded region has an area of 34.5 square meters.

Answer:

i might need more info unless this is the only questions

Step-by-step explanation:

I'm not sure what it means by "define the types of linear" (maybe theres a given function?), but to find the x intercept you need to make y 0. For example:

if we have a function

f(x) = 2x + 1

and we want to find the x intercept we substitute 0 to y

0 = 2x + 1

not

f(0) = ......

Answer:

To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’. How do you find the Y intercept in a word problem? When a word problem involves a constant rate or speed and a beginning amount, it can be written in slope-intercept form: y=mx+b.
