Answer:25.12

Explanation:

1 Simplify \frac{2}{5}s

s to \frac{2s}{5}

\frac{1}{2}+\frac{2s}{5}=s-\frac{3}{4}

=s−

2 Multiply both sides by 55.

\frac{5}{2}+2s=5s-\frac{15}{4}

+2s=5s−

3 Subtract 2s2s from both sides.

\frac{5}{2}=5s-\frac{15}{4}-2s

=5s−

−2s

4 Simplify 5s-\frac{15}{4}-2s5s−

−2s to 3s-\frac{15}{4}3s−

\frac{5}{2}=3s-\frac{15}{4}

=3s−

5 Add \frac{15}{4}

to both sides.

\frac{5}{2}+\frac{15}{4}=3s

=3s

6 Simplify \frac{5}{2}+\frac{15}{4}

to \frac{25}{4}

\frac{25}{4}=3s

=3s

7 Divide both sides by 33.

\frac{\frac{25}{4}}{3}=s

8 Simplify \frac{\frac{25}{4}}{3}

to \frac{25}{4\times 3}

4×3

\frac{25}{4\times 3}=s

4×3

9 Simplify 4\times 34×3 to 1212.

\frac{25}{12}=s

10 Switch sides.

s=\frac{25}{12}s=

Done

Decimal Form: 2.083333

Two opposite forces acting perpendicular to an axis cause

Greeley [361]

Two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.

<h3>What is couple?</h3>

Couple is the pair of force of equal magnitude which acts in opposite direction to each other. The moment of couple is known as the troque, which can be calculate as,

$\tau=Fs$

Here, (F) is the magnitude of one of the force and (s) is the perpendicular distance of force acting on axis.

Here, the two opposite forces are given which acts perpendicular to an axis. Now suppose there is the magnitude of both the force (F) is equal and the perpendicular distance from the axis is also same.

Thus, from the above definition of moment of couple, they produce, torque or moment of couple.

Hence, the two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.

37 cos(x2) dx 0 Do the following. (a) Find the approximations T8 and M8 for the given integral. (Round your answer to six decima

dusya [7]

The approximations T8 and M8 for the given integral are:

T8 = 33.386321; and
M8 = 33.50794

<h3>What is an integral?</h3>

An Integral is a variable of which a given function is the derivative, i.e. it gives that function when differentiated and may express the area under the curve of the function's graph.

<h3>What is the explanation to above answer?</h3>

Given:

F(x) = 37 cox (x²)

Internal = [0,1] n = 8 in Δ x = 1/8

The sub intervals are:

[0, 1/8], [1/8, 2/8], [2/8, 3/8], [ 3/8, 4/8], [ 4/8, 5/8], [ 5/8, 6/8], [6/8, 7/8], [ 7/8, 1]

The mid points are given as:

1/16, 3/16, 5/16, 7/16, 9/16, 11/16, 13/16, 15/16

and X₀ = 0, X₁ = 1/8, X₂ = 2/8

Using the Trapezium Rule which states that:

$\int\limits^1_0 cos(x)^{2} } \, dx$ = Δx/2 $[f(xo) + 2f(x1) 2f(x2) + ....+ 2f(x7) + f(x8)]$

= 1/1Q[f(0) + 2f (1/8) + 2f(2/8) + ....+ 2f(7/8) + f(1)]

= 0.902333

Now

T8 = $\int\limits^1_0 {37Cos(x)^{2} } \, dx$

= $37\int\limits^1_0 {(0.902333)} } \, dx$

= 37 (0.902333)

T8 = 33.386321

It is to be noted that the midpoints rule is given as;

$\int\limits^1_0 {Cos(x)^{2} } \, dx$ = Δx [f(1/16) + (3/16) + .... + f(15/16)]

= 1/8[f(1/16) + f (3/16) + f(5/16) + f(7/16) + f(9/16) + f(11/16) + f(13/16) + f(15/16)]

= 0.905620

From the above,

M8 = $\int\limits^1_0 {37 Cos(x)^{2} } \, dx$

= $37\int\limits^1_0 {Cos(x)^{2} } \, dx$

= 37 (0.905620)

M8 = 33.50794

Each of 6 samples has a different standard deviation. How many of the 6

ivann1987 [24]

The number of six samples that could belong to the same population is equivalent to six.

Option A is the correct answer.

<h3>What is the standard deviation?</h3>

The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.

The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.

Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.
