A student spins a spinner and rolls a number cube
Is it dependant or independant and why?

Answers

Answer 1

Answer: Independent; the results of the spinner will not affect the results of the number die and vice versa.

Lines g and h are parallel and m 1 = 65°. What is m 8?

A.
25°

B.
65°

C.
115°

D.
155°

Answers

Answer:

Option B $65\°$

Step-by-step explanation:

we know that

If the lines g and h are parallel

then

$m<8=m<1$ -----> by alternate exterior angles

we have that

$m<1=65\°$

therefore

$m<8=65\°$

m 1 = m 4 (v.o.a.)
since g parallel to h
m 4 = m 8
m 8 = m 1 = 65°

What is the square root of the number 441? How do you know this and how did you solve this?

Answers

the square root of 441 is 21. for this kind of question you should know 11^2 is 121 so now you should choose a bigger number for 441. it does not have any formula. :))

Find the slope of the line passing through each of the following pairs of points (0, 7), (0, −8)

Answers

The slope of the line passing through the pairs of points (0, 7), and (0, −8) is not defined.

Here,

We have to find the slope of the line passing through the pairs of points (0, 7), and (0, −8).

What is slope of the line?

A measure of its steepness is called slope of line.

Now,

The points are (0, 7) and (0, -8)

Hence, Slope of the line is calculate as;

$m = (y_(2) -y_(1) )/(x_(2)-x_(1) )$

$m = (-8 -7 )/(0)-0 } = (-15)/(0)$

Which is undefined.

Hence, The slope of the line passing through the pairs of points (0, 7), and (0, −8) is not defined.

The sum of two consecutive even integers divided by four is 189.5

Answers

Two consecutive even integers means that the numbers are two apart. Let's call the first even integer "n." The consecutive even integer would then be "n+2." Using these two expressions, create an equation that you can solve for the value of the integers:
(n + n + 2)/4 (sum of the integers divided by four) = 189.5

Now you can solve for the value of n:
$(n+n+2)/(4) = 189.5\nn+n+2 = 189.5(4)\n2n + 2 = 758\n2n = 756\nn = 378$

Since n = your first even integer, that means your first even integer is 378 and your consecutive even integer is 380.

Answer: 378 and 380

STEP 1:
find first integer

sum= addition
x= first consecutive even integer
x+2= second consecutive even integer

(x + (x+2))/4= 189.5
multiply both sides by 4

x + (x + 2)= 758
combine like terms

2x + 2= 758
subtract 2 from both sides

2x= 756
divide both sides by 2

x= 378 first integer

STEP 2:
substitute first integer to find second

= x + 2
= 378 + 2
= 380 second integer

CHECK:
(378 + 380)/4= 189.5
758/4= 189.5
189.5= 189.5

ANSWER: The first consecutive even integer is 378 and the second consecutive even integer is 380.
