Answer:

True

Step-by-step explanation:

The nature of roots of a quadratic equation are determined by

${b}^{2} - 4ac$

where a, b, and c are the coefficients of the quadratic equation

$a {x}^{2} + bx + c = 0$

Therefore it is true that, the roots of a quadratic equation depend on the values of the coefficients.

Answer:

The second answer, and possibly the first answer as also true.

She did run a test that would indicate its an unbalanced dice, but this wasn't tried out with a different person throwing the dice.

Step-by-step explanation:

This is because from the computer generator results we see 11 of the 25 values are estimating at 1/5 when we know dice are 1/6 and more than 1/2 show just under 1/5 which balances this to be 1/6

But there are 9/25 tests that showed values under 10 throws found a 6 in 9/25 events = 1/3 approx out of 1/10 of the throws, and 1/3 is still a higher value than 1/6 of the multiple throws so indicates 100 throws would not be enough to tell as we cannot possibly assume her results are comparable with a computer generator.As the computer generator completed 25 x 100 throws and have just compared only x10 in relation to 1/10 of the events of the generated computer. This showing 9 of the 25 (100) throw events in relation scores 1/3 of the results a 6. The answer is she would need to throw somewhere between 1000 and 3000 to compare to the computers results.

The physical education instructor asked each student to do a total of 36 pull-ups and push-ups in 1 minute. The instructor wante

NeTakaya

Answer: Pull-ups = 4 and push up = 32

Step-by-step explanation:

Let x represents number of pull ups in one minute.

And, y represents number of push ups in one minute.

Therefore, According to the question,

Each student to do a total of 36 pull-ups and push-ups in 1 minute.

⇒ x+y= 36

But, again from equation, The instructor wanted students to do 8 times as many push-ups as pull-ups.

Therefore, 8x = y

Thus, required system of linear equations that represents this situation is,

x+y= 36 and 8x = y , where x is the number of pull ups and y is the number of push ups in one minute.

By solving these two equations we get, x=4 and y= 32

That is, In one minute 4 pull ups and 32 push ups are required.

At noon, the shadow of a flagpole is 30 feet long. At the same time, the shadow of a 200-foot tall building is 50 feet long. Wha

Wewaii [24]

We can use ratios to solve this problem. If a 200 foot tall building has a shadow 50 feet long at noon, then the shadow is one fourth of the height.

Since is at the same time, the shadow of the flagpole is a fourth of the height. So, the height of the flagpole is 120 feet.

Hope this helps!
