According to diagram, this triangle is a right angled triangle.

So we can use trigonometric ratio to find the value of <u>x</u>

<u>Now</u><u>,</u>

\:\bf{sin 60° = \frac{x}{3}}

=> \:\sf{\frac{\sqrt(3)}{2}= \frac{x}{3}}

=> \:\sf{\frac{3\sqrt(3)}{2}= x}

Hope this helps you!

Answer:

x = 1.5\sqrt{3}

Step-by-step explanation:

using the sine ratio in the right triangle and the exact value

sin60° = \frac{\sqrt{3} }{2} , then

sin60° = \frac{opposite}{hypotenuse} = \frac{x}{3} = \frac{\sqrt{3} }{2} ( cross- multiply )

2x = 3\sqrt{3} ( divide both sides by 2 )

x = 1.5\sqrt{3}

A Copy of machine produces 80 copies in 5 minutes. How many copies would be produced in 40 minutes?
BlackZzzverrR [31]
The answer would be 640. To find the number of how many copies are produced in 1 minute you have to write 80 divided by 5 which equals 16. Now you multiply 16 and the 40 minutes which gives you 640 copies.

A function f is defined by f(x) = 2x - 3. By writing the full working, write the values of (a) f(0) (b) f(-2) (c) f(3) (d) f(-1)
AlladinOne [14]
A) f(x) = 2x - 3
f(0) = 2(0) - 3
f(0) = 0 - 3
f(0) = -3

b) f(x) = 2x - 3
f(-2) = 2(-2) - 3
f(-2) = -4 - 3
f(-2) = -7

c) f(x) = 2x - 3
f(3) = 2(3) - 3
f(3) = 6 - 3
f(3) = 3

d) f(x) = 2x - 3
f(-1) = 2(-1) - 3
f(-1) = -2 - 3
f(-1) = -5

Use the given information to bound the p-value of the F statistic for a one-tailed test with the indicated degrees of freedom. F
lianna [129]

Answer:

The range of the <em>p</em>-value is: 0.050 < <em>p</em>-value < 0.100.

Step-by-step explanation:

For checking the equivalence of two population variances of independent samples, we use the <em>f</em>-test.

The test statistic is given by:

F=\frac{S_{1}^{2}}{S_{2}^{2}}\sim F_{\alpha, (n_{1}-1)(n_{2}-1)}

It is provided that the hypothesis test is one-tailed.

The computed value of the test statistic is:

<em>F</em> = 4.23.

The degrees of freedom of the numerator and denominator are:

df_{1}=4\\df_{2}=5

Use MS-Excel to compute the <em>p</em>-value as follows:

Step 1: Select function fX → F.DIST.RT.

Step 2: A dialog box will open. Enter the values of f-statistic and the two degrees of freedom.

*See the attachment below.

Step 3: Press OK.

The <em>p</em>-value is, 0.0728.

The range of the <em>p</em>-value is:

0.050 < <em>p</em>-value < 0.100
