Answer:

<u> $9\sqrt{2}$ </u>

Step-by-step explanation:

The given question is :

$\sqrt{8} +3\sqrt{2} +\sqrt{32}$

8 = 4 * 2

32 = 16 * 2

$\sqrt{8} =\sqrt{4*2} = 2\sqrt{2} \\\sqrt{32} =\sqrt{16*2} =4\sqrt{2}$

∴ $\sqrt{8} +3\sqrt{2} +\sqrt{32}$

= $2\sqrt{2} +3\sqrt{2} +4\sqrt{2}$

= $9\sqrt{2}$

When dropped, a super ball will bounce back to 80% of its peak height,continuing on in this way for each bounce.

Liono4ka [1.6K]

An expression for the height of the nth bounce is 0.80X^N = Height.

<h3><u>Equations</u></h3>

Since when dropped, a super ball will bounce back to 80% of its peak height, continuing on in this way for each bounce, to determine an expression for the height of the nth bounce the following calculation must be performed:

X = Initial value
80% = 0.80
N = Number of times the ball bounces
0.80X^N = Height

Therefore, an expression for the height of the nth bounce is 0.80X^N = Height.

Andrew is flying a kite held by 175 meters of string that makes an angle of elevation with the ground of 40. Emma is standing di

Alja [10]

Answer:

$x=134.05m$

Step-by-step explanation:

From the question we are told that:

Slant Height of Kite $h_s=175$

Angle $\theta=40 \textdegree$

Since Emma,The Kite and Andrew forms a right angle triangle

Generally the equation for distance between Andrew from Emma is mathematically given by

$x=h_scos\theta$

$x=175cos40$

$x=134.05m$

In the largest clinical trial ever conducted, 401,974 children were randomly assigned to two groups. The treatment group consis

BARSIC [14]

Answer:

The requirements for the hypothesis test does satisfied the method for testing the claim that from two population proportions the rate of polio is less for children given the salk vaccine.

Step-by-step explanation:

The percentage of children in the treatment group was:

(201229/401974)*100 = 49.9%

The percentage of children given placebo was:

(200745/401974)*100 = 50.1%

The percentage of children that developed polio in the treatment group:

(33/200745)*100 = 0.0164%

The percentage of children that developed polio in the placebo group:

(115/201229)*100 = 0.0571%

The percentage difference between the two group:

((0.0571-0.0164)/0.0571) = 61.62%

Therefore:

The amount of children used for each group was almost divided into half of the total amount of children. The test revealed although very small percentages of the both group developed polio, 68.62% more children given placebo than the children that was given the salk vaccine. Therefore, the study shows that the rate of polio is less for children given the salk vaccine and the the hypthesis test is satisfied.
