Answer:

x = \sqrt{6}

Step-by-step explanation:

Since the given triangle is equilateral the all 3 sides would be:

\sqrt{6} +\sqrt{6} or \sqrt{12}. Now we know that the base of the right triangle is \sqrt{6} and the hypotenuse is \sqrt{12}. Therefore we can say;

A² + B² = C²

(\sqrt{6})² + x² = (\sqrt{12})²

6 + x² = 12

x² = 12 - 6

x² = 6

x = \sqrt{6}

Therefore; <u>x = </u>\sqrt{6}<u> is the length of x</u>, in simplest radical form.

The mean is the average . the sum of number over the number of observation

x1=525

x2=487

s.d1=59.42

s.d2=51.74

n1=16

n2=12\alpha =0.05

Determine the hypothesis

H_{0}: u1≤u2

H_{a} :u1>u2

find the degree of freedom(\frac{s1^2}{n1} +\frac{s2^2}{n2} )^2/(\frac{s1^2}{n1} )^2/n1-1+(s2^2/n2)^2/n2-1\\\\(\frac{59.42^2}{16} +\frac{51.7476^2}{12} )^2/(\frac{59.42^2}{16} )^2/16-1+(51.74^2/12)^2/12-1

p-value is the probability of obtaining the value of the test statistics. In the column of t-value in the row df=25

0.025<P<0.05

if the P value is actually less than or the same as the significant level, then the null hypothesis is rejected

P<0.05   rejected H

There are 128 students going on a field trip to pan for gold. If they are going in vans that hold 7 students each, how many vans
Viefleur [7K]
128/7 is roughly 18.3 so you would need 19 vans. 18 of them would fit all 7 so you’d have 126 so the last van would fit 2 students meaning it won’t be full

Melvin is pushing a tire during workout with the dimensions shown how many square inches of space has a tire covered after Melvi
valentina_108 [34]

Answer:

The answer is below

Step-by-step explanation:

The question is not complete, but I would show you how to solve it.

Solution:

A circle is the locus of a point such that its distance from a fixed point which is its center is always constant.

The tire has the shape of a circle. Therefore the distance the tire covers if it is pushed around once is the same as the circumference of the tire. The circumference is given by:

Circumference = 2πr; where r is the radius of the tire

Let us assume that the tire has a radius of 7 cm. Hence:

Circumference = 2π(7) = 44 cm

If the tire moves around 5 times, the distance covered = 5 * circumference of tire = 5 * 44 cm = 220 cm

Area of a rectangle=length×breath

Area=24×10

=240cm²
