The test to detect the presence of a certain protein is 98% accurate for corn plants that have the protein and 97% accurate for

larisa [96]

Using the given percentages, it is found that the probability that a randomly chosen plant is detected incorrectly is 0.02965 = 2.965%.

<h3>Percentages:</h3>

The percentages associated with an incorrect detection are:

2% of 3.5%(have the protein).

3% of 96.5%(do not have the protein).

Hence:

$p = 0.02(0.035) + 0.03(0.965) = 0.02965$

The probability that a randomly chosen plant is detected incorrectly is 0.02965 = 2.965%.

The commutative property is a property of <em>addition</em>, not of <em>subtraction</em>. It can work in a subtraction problem if you keep the sign with the number, so you're adding positive and negative numbers.

3 - 6 + 5

= (3) + (-6) + (5)

= (3) + (5) + (-6)

A ball is kicked 4 feet above the ground with an initial vertical velocity of 55 feet per second. The function h(t)=−16t2+55t+4

kramer

<u>Given</u>:

A ball is kicked 4 feet above the ground with an initial vertical velocity of 55 feet per second.

The function $h(t)=-16t^2+55t+4$ represents the height h(in feet) of the ball after t seconds.

We need to determine the time of the ball at which it is 30 feet above the ground.

To determine the time that it takes for the ball to reach a height of 30 feet above the ground, let us substitute h(t) = 30, we get;

$30=-16t^2+55t+4$

$26=-16t^2+55t$

Adding both sides of the equation by 16t², we get;

$16t^2+26=55t$

Subtracting both sides of the equation by 55t, we have;

$16t^2-55t+26=0$

Let us solve the quadratic equation using the quadratic formula, we get;

$t=\frac{-(-55) \pm \sqrt{(-55)^2-4(16)(26)}}{2(16)}$

$t=\frac{55 \pm \sqrt{3025-1664}}{32}$

$t=\frac{55 \pm \sqrt{1361}}{32}$

$t=\frac{55 \pm 36.89}{32}$

$t=\frac{55 + 36.89}{32} \ or \ t=\frac{55- 36.89}{32}$

$t=\frac{91.89}{32} \ or \ t=\frac{18.11}{32}$

$t=2.9 \ or \ t=0.6$

The value of t is t = 0.6 because this denotes the time taken by the ball to reach a height of 30 feet from the ground.

Therefore, the time taken by the ball to reach a height of 30 feet above the ground is 0.6 seconds.
