Given:

Equation of a line is

3x-4y=8

To find:

The equation of line in slope intercept form that is parallel to line a and goes through point (24, 6).

Solution:

If a linear equation is ax+by+c=0, then

Slope=-\dfrac{a}{b}

In the equation 3x-4y=8, a=3 and b=-4, thus the slope of the line is

Slope=-\dfrac{3}{-4}

Slope=\dfrac{3}{4}

We know that, slope of two parallel lines are same. So, slope of parallel line is

m=\dfrac{3}{4}

The parallel line passes through (24, 6) and have slope m=\dfrac{3}{4}, so the equation of line is

y-6=\dfrac{3}{4}(x-24)

y-6=\dfrac{3}{4}(x)-\dfrac{3}{4}(24)

y-6=\dfrac{3}{4}(x)-18

Add 6 on both sides.

y=\dfrac{3}{4}(x)-18+6

y=\dfrac{3}{4}(x)-12

Therefore, the equation of parallel line in slope intercept form is y=\dfrac{3}{4}(x)-12.

The formula to find the volume of the composite solid is: C. V = πr²h + ⅔πr³.

<h3>How to Find the Volume of a Composite Solid?</h3>

The volume of the composite solid in the image given = Volume of cylinder + volume of hemisphere.

Volume of cylinder = πr²h

Volume of hemisphere = ⅔πr³

Therefore, formula to find the volume is: C. V = πr²h + ⅔πr³.

disa [49]

Answer:

The 90 % confidence limits are (-2.09, 8.09).

Since the calculated values do not lie in the critical region we accept our null hypothesis.

Step-by-step explanation:

The null and alternative hypothesis are given by

H0: σ₁²= σ₂² against Ha: σ₁² ≠ σ₂²

Confidence interval for the population mean difference is given by

(x`1- x`2) ± t √S²(1/n1 + 1/n2)

Where S ²= (n1-1)S₁² + S²₂(n2-1)/n1+n2-2

Critical value of t with n1+n2-2= 50+ 35-2= 83 will be -1.633

Now calculating

S ²=34* (12.8)²+ (14.6)²*49/83= 192.96

Now putting the values in the t- test

(75.1 -72.1) ± 1.633 √ 192.96(1/35 +1/50)

=3 ±  5.09

=-2.09, 8.09  is the 90 % confidence interval for the difference

The 90 % confidence limits are (-2.09, 8.09).

Since the calculated values do not lie in the critical region we accept our null hypothesis.
