Answer:

False

True

Step-by-step explanation:

There cannot be an orange bead in the bag. FALSE

they never said how many colors are in the bag so there is always a possibility.

There must be exactly 1 yellow bean in the bag. FALSE

Just because Ryan only selected 1 yellow bean doesn't mean there is only 1 in the bag.

After 15 trials, Ryan has selected exactly 6 white beads. TRUE

2/5 = 6/15. Ryan has selected 6 white beads

After 16 trials, the experimental probability of selecting a blue bead is 1/4. TRUE

Ryan has selected 4/16 blue beads at the 16th trial.

After 17 trials, the experimental probability of selecting a red bead is 5/17. TRUE

at trial 17, the red bean ratio is 5/17.

1/3 = 5/15 and then 2 more trials make it 5/17.

Answer:

108 miles

Step-by-step explanation:

Given the points (0.5, 135) and (2,81)

Diatnce between two points :

D = √(x2 - x1)² + (y2 - y1)²

X1 = 0.5 ; y1 = 135 ; x2 = 2 ; y2 = 81

D = √(2^2 - 0.5^2) + (81^2 - 135^2)

D = √(4 - 0.25) + (6561 - 18225)

D = √3.75 −11664

D = 107.98263

D = 108 miles

A metalworker has a metal alloy that is 15% copper and another alloy that is 75% copper. How many kilograms of each alloy shou

lisov135 [29]

48 kilograms of 15 % copper is combined with 72 kilograms of 75 % copper to create 120 kg of a 51% copper alloy

Solution:

Let "x" be the kilograms of 15 % copper

Then, (120 - x) be the kilograms of 75 % copper

Then, according to question,

"x" kilograms of 15 % copper is combined with (120 - x) kilograms of 75 % copper to create 120 kg of a 51% copper alloy

Thus we frame a equation as:

15 % of x + 75 % of (120 - x) = 51 % of 120

Solve the equation for "x"

$15 \% \times x + 75 \% \times (120-x) = 51 \% \times 120\\\\\frac{15}{100} \times x + \frac{75}{100} \times (120-x) = \frac{51}{100} \times 120\\\\0.15x + 0.75(120-x) = 0.51 \times 120\\\\0.15x + 90 - 0.75x = 61.2\\\\0.6x = 90 - 61.2\\\\0.6x = 28.8\\\\Divide\ both\ sides\ by\ 0.6\\\\x = 48$

Thus 48 kilograms of 15 % copper used

Then, (120 - x) = (120 - 48) = 72

Thus, 72 kilograms of 75 % copper is used
