Can U guys please help with this. :)

V125BC [204]

Answer:

x=0.9

Step-by-step explanation:

1.convert to improper fractions

4x+9/7/3=3x/0.5

2.Apply fraction cross multiply

(4x+9) * 0.5=7/3 * 3x

3. simplify

(4x+9) *0.5 =7x

4.Expand

2x+4.5=7x

5.Subtract 4.5 from both sides

2x=7x-4.5

6.Subtract 7x from both sides

2x-7=7x-4.5-7x

7.Simplify

-5x=-4.5

7.Divide by -5

x=0.9

Find the sample size necessary in order to be 95% confident when determining the true mean weight within 2 units (EC2). Assume t

bogdanovich [222]

Answer:

(c) 43.

Step-by-step explanation:

Given:

Margin of error (E) = 2

Sample variance $(s^{2})$ = 44

Confidence level = 95%

The z- value at 95% confidence level is 1.96.

The sample using the provided information can be calculated as:

$n=(\frac{z(s)}{E})^{2} \\n=\frac{z^{2} s^{2} }{E^{2} } \\n=\frac{1.96^{2} (44) }{2^{2} }\\n= 42.52\\n=43$

Hence, the correct option is (c) 43.

What angle has the same sine value between 0-180? as Sin 24

Inessa05 [86]

Answer:

$Sin156$

Step-by-step explanation:

Given

$Sin24$

Required

Find equivalent between 0 to 180;

Let 24 be represented by $\theta$

So, $\theta = 24$

From Trigonometry ratios;

$Sin\theta = Sin(180 - \theta)$ where $0\leq \theta \leq 180$

Recall that $\theta = 24$

So, we have to substitute 24 for $\theta$ in the above expression.

This gives

$Sin24= Sin(180 - 24)$

Subtract 24 from 180

$Sin24= Sin156$

Hence, the equivalent of $Sin24$ is $Sin156$
