Answer:

y = 1.5x + 1

Step-by-step explanation:

→ Choose 2 points

( 2 , 4 ) ( -2 , -2 )

→ Find the gradient

-6 ÷ -4 = 1.5

→ Write into format

y = 1.5x + c

→ Substitute in ( 2 , 4 )

4 = 3 + c

→ Minus 3 from both sides

1 = c

y = 1.5x + 1

A stack of 180 cards is placed next to a ruler in the height of stack is measured to be 3 fourths of an inch how thick is one ca
Juli2301 [7.4K]

Height of the stack = 3 fourth of an inch

                                = \frac{3}{4} × (1 inch)

Height of 180 cards = \frac{3}{4} × (1 inch)

Thickness of 1 card = \frac{3}{4} × \frac{1}{180} × (1 inch)

                                = \frac{1}{240} × (1 inch)

An experiment consists of drawing a marble out of a bag, observing the color, and then placing it back in the bag. Suppose the e
Elan Coil [88]
The experimental data suggest that

\mathbb P(\text{red})\approx\dfrac{38}{75}
\mathbb P(\text{blue})\approx\dfrac{23}{75}
\mathbb P(\text{green})\approx\dfrac{11}{75}
\mathbb P(\text{yellow})\approx\dfrac3{75}

Because the marble is replaced after being drawn, and so the number of marbles of a given color remains the same, the event of drawing any given color is independent of what was drawn before. So

\mathbb P(\text{2 consecutive yellows})\approx\dfrac3{75}\cdot\dfrac3{75}=\dfrac1{625}
