Sever21 [200]

As botanist is studying the effect of water and fertilizer on certain flowering plants.

Three Distinct amounts of water having different amount of fertilizer contents in them is used for the purpose of Experimentation.

That is, Plants are given 8, 16, or 32 ounces of water each day, and the water that is given contains either a 2%, 5%, or 10% dissolved fertilizer solution.

Number of treatments used in this experiment taking 8, 16, or 32 ounces of water each day taking two at time= $_{2}^{3}\textrm{P}=6$ that is (8,16),(16,8),(8,32),(32,8),(16,32),(32,16).

So, Number of treatments used in this experiment taking 8, 16, or 32 ounces of water each day taking all at time = $_{3}^{3}\textrm{P}=6$

that is (8,16,32) , (8,32,16),(16,8,32),(16,32,8),(32,8,16),(32,16,8)

These are the orders in which water is used for flowering the plants that is first day 8 ounces of water, second day 16 ounces of water, third day 32 ounces of water, or first day 8 ounces of water, second day 32 ounces of water, third day 16 ounces of water, ...........

So, there are 6 possible arrangements using (8, 16 and 32 ) ounces of water taking all at a time and 6 possible arrangements using (8, 16 and 32 ) ounces of water taking two at a time.

Or there are total of [6 × 3= 18] + [6 × 2= 12],=30 treatments.

Let Z be a standard normal random variable and calculate the following probabilities, drawing pictures wherever appropriate. (Ro

puteri [66]

Answer:

(a) P(0 ≤ Z ≤ 2.87)=0.498

(b) P(0 ≤ Z ≤ 2)=0.477

(d) P(−2.20 ≤ Z ≤ 2.20)=0.972

(e) P(Z ≤ 1.01)=0.844

(f) P(−1.95 ≤ Z)=0.974

(g) P(−1.20 ≤ Z ≤ 2.00)=0.862

(h) P(1.01 ≤ Z ≤ 2.50)=0.150

(i) P(1.20 ≤ Z)=0.115

(j) P(|Z| ≤ 2.50)=0.988

Step-by-step explanation:

(a) P(0 ≤ Z ≤ 2.87)

In this case, this is equal to the difference between P(z<2.87) and P(z<0). The last term is substracting because is the area under the curve that is included in P(z<2.87) but does not correspond because the other condition is that z>0.

$P(0 \leq z \leq 2.87)= P(z$

(b) P(0 ≤ Z ≤ 2)

This is the same case as point a.

$P(0 \leq z \leq 2)= P(z$

This is the same case as point a.

$P(-2.2 \leq z \leq 0)= P(z$

(d) P(−2.20 ≤ Z ≤ 2.20)

This is the same case as point a.

$P(-2.2 \leq z \leq 2.2)= P(z$

(e) P(Z ≤ 1.01)

This can be calculated simply as the area under the curve for z from -infinity to z=1.01.

$P(z\leq1.01)=0.844$

(f) P(−1.95 ≤ Z)

This is best expressed as P(z≥-1.95), and is calculated as the area under the curve that goes from z=-1.95 to infininity.

It also can be calculated, thanks to the symmetry in z=0 of the standard normal distribution, as P(z≥-1.95)=P(z≤1.95).

$P(z\geq -1.95)=0.974$

(g) P(−1.20 ≤ Z ≤ 2.00)

This is the same case as point a.

$P(-1.20 \leq z \leq 2.00)= P(z$

(h) P(1.01 ≤ Z ≤ 2.50)

This is the same case as point a.

$P(1.01 \leq z \leq 2.50)= P(z$

(i) P(1.20 ≤ Z)

This is the same case as point f.

$P(z\geq 1.20)=0.115$

(j) P(|Z| ≤ 2.50)

In this case, the z is expressed in absolute value. If z is positive, it has to be under 2.5. If z is negative, it means it has to be over -2.5. So this probability is translated to P|Z| < 2.50)=P(-2.5<z<2.5) and then solved from there like in point a.

$P(|z|$

Find the length of the leg. If your answer is not an integer, leave it in simplest radical form. answer asap pls

Nitella [24]

A 45-45 90 triangle has two lengths that are equal, and the hypotenuse is √2 times those lengths.

Therefore:
Let x = the length of a leg (doesn't matter which one, they are equal)
√2 * x = 24 Divide both sides by √2
x = 24 / √2
To get the radical out of the denominator, multiply the right side by √2/√2
x = 24√2 / 2
x = 12√2 Answer is B
