The measure of RST can be represented by the expression (6x + 12)°.

Valentin [98]

Answer:

The measure of angle RST is $120\°$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

$m$ -----> equation A

$m$ -----> equation B

equate equation A and equation B

$(6x+12)\°=78\°+(3x-12)\°$

$6x-3x=78\°-24\°$

$3x=54\°$

$x=18\°$

The measure of angle RST is equal to

$m$

Artemon [7]

Answer:

Part A

The probability of the treatment groups mean being greater than the control group mean by 8points or more = (26+8+2)/1000 = 0.036

Part B

Yes, the result is statistically significant because the probability of the difference being 8point or more is less than 5% significant level

Part C

The answers is 0.036 means that there is a very little chance of obtaining difference of 8points or more by random chance. So, if the difference between treatment group mean and control group mean is at least 8 , then the result is significant which means protein shaken is actually helpful in speeding up the weight-10 process

Larry reads that 1 out of 4 eggs contains salmonella bacteria, so he never uses more than 3 eggs in cooking. If eggs do or don't

aleksley [76]

Answer:

57.8125% or approx. 57.8%

Step-by-step explanation:

There is a 1/4, or 25%, or 0.25 chance that an egg has salmonella.

Thus, there is a 75%, or 0.75 chance that an egg DOESN'T contain salmonella.

Let's find the probability that all 3 of Larry's eggs are free from salmonella. Larry would have to hit that 75% chance 3 times in a row. The chance of that happening is:

0.75 * 0.75 * 0.75 = $0.75^3$ = 0.421875
