3 0

Answer:

83.3%

Step-by-step explanation:

The probability of rolling a 3 on a 6-sided dice is 1/6

Since you don't want a three, there's a 5/6 chance of not rolling a 3

5/6 (use calculator and divede 5 by 6) = 0.833333 (move decimal 2 to the right) = 83.3%

Therefore, the most reasonable answer would be C, 83.3%

A line passes through tge points (1,-3) and (4,6) what is the zero of this line ?

Maru [420]

Answer:

The zero of the line is (2,0)

Step-by-step explanation:

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

We are given the points (1,-3) and (4,6). Substituting:

$\displaystyle y+3=\frac{6+3}{4-1}(x-1)$

Operating:

$\displaystyle y+3=\frac{9}{3}(x-1)$

$y+3=3(x-1)$

The zero of this line can be found by making y=0 and solving for x:

0+3=3(x-1)

3=3x-3

Adding 3:

6=3x

Solving:

x = 2

The zero of the line is (2,0)

Find the volume. 576 ft3 448 ft3 640 ft3 520 ft3

Tems11 [23]

Hello there!

Answer: C. 640ft³

Explanation:

V=l*w*h (Volume equals length times width and times the height.)

V=l*w*h

The length is 8ft.

The weight is 10ft.

The height is 8ft.

V=l*w*h

8*10*8

8*10=80

80*8=640

=640ft3

Hope this helps!

Thanks!

Have a great day!

A line is drawn so that it passes through the points (-3, -1) and (4, 2).

marishachu [46]

Answer:

(A) $\boxed{\bold{y=\frac{3}{7}x+\frac{2}{7}}}$

(B) $\boxed{\bold{2 \ = \ \frac{3}{7} * \ 4 \ + \ \frac{2}{7} }}$

Explanation:

(A) Slope: y = mx + b

m = 3/7

b = 2/7

Slope = $\bold{\frac{y_2-y_1}{x_2-x_1}}$

$\bold{\left(x_1,\:y_1\right)=\left(-3,\:-1\right),\:\left(x_2,\:y_2\right)=\left(4,\:2\right)}$

M = $\bold{\frac{2-\left(-1\right)}{4-\left(-3\right)}: \ \frac{3}{7} }$

Y intercept

$\bold{y=\frac{3}{7}x+b}$

Plug in $\bold{\left(-3,\:-1\right)\mathrm{:\:}\quad \:x=-3,\:y=-1}$

$\bold{-1=\frac{3}{7}\left(-3\right)+b}$

Isolate B

$\bold{-1=\frac{3}{7}\left(-3\right)+b}$

b = $\bold{\frac{2}{7} }$

(B) 4 = x, 2 = y

2 = 3/7 * 4 + 2/7
