Step-by-step explanation:

[tex]x=3 \\\\n=50\\\\\hat{p}=\frac{x}{n}=0.06\\\\\hat{q}=1-\hat{p}=0.94[/tex]

In point a:

[tex]98\%[/tex] confidence interval for population proportion (p):

[tex]c=98\%=0.98\\\\\alpha=1-c=0.02\\\\\frac{\alpha}{2}=\frac{0.02}{2}=0.01\\\\z_{\frac{\alpha}{2}}=2.326\\\\[/tex]

For point b:

[tex]98\% \ confidence\ interval =\hat{p} \pm z_{\frac{\alpha}{2}} \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\\\\[/tex]

                                        [tex]=0.06 \pm 2.326 \sqrt{\frac{0.06\times 0.94}{50}}\\\\ =0.06 \pm 2.326 (0.0336)\\\\=0.06 \pm 0.078\\\\98\% \ CI =(-0.018, 0.138)[/tex]

For point c:

[tex]The\ difference\ between \ 98\% \ CI\ is \ -0.018\ to\ 0.138[/tex]

(-b±√(b²-4ac))/(2a)

Answer:

x=120±6434−−−√

x=−4.996

x=244.996

Find the Solution for

−125x2+30000x+153000=0

using the Quadratic Formula where

a = -125, b = 30000, and c = 153000

x=−b±b2−4ac−−−−−−−√2a

x=−30000±300002−4(−125)(153000)−−−−−−−−−−−−−−−−−−−−−√2(−125)

x=−30000±900000000−−76500000−−−−−−−−−−−−−−−−−−−√−250

x=−30000±976500000−−−−−−−−√−250

The discriminant b2−4ac>0

so, there are two real roots.

Simplify the Radical:

x=−30000±1500434−−−√−250

x=−30000−250±1500434−−−√−250

Simplify fractions and/or signs:

x=120±6434−−−√

which becomes

x=−4.996

x=244.996

Answer: A

Step-by-step explanation:

The equation sin²(2π)+ cos²(2π) = 1 will be 0² + 1² = 1. Then the correct option is A.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

The equation is given below.

sin²(2π)+ cos²(2π) = 1

We know that the value of sin 2π is 0 and the value of cos 2π is 1.

Then the equation will be

0² + 1² = 1

Then the correct option is A.

Answer:

95% of the confidence interval for q is

(0.05809 , 0.1183)

Step-by-step explanation:

Step:1

Given that the random sample of 340 electronic components manufactured by a certain process is tested, and 30 are found to be defective.

sample proportion

                   [tex]q^{-} = \frac{x}{n} = \frac{30}{340} = 0.0882[/tex]

Step:2

95% of the confidence interval is determined by

[tex](q - Z_{0.05} \sqrt{\frac{pq}{n} } , q + Z_{0.05} \sqrt{\frac{pq}{n} } )[/tex]

[tex]((0.0804 -1.96 \sqrt{\frac{0.0804 X0.9118}{340} } ,0.0804 +1.96 \sqrt{\frac{0.0804 X0.9118}{340})[/tex]

[tex]( 0.0882- 1.96 \sqrt{0.000236} , 0.0882 + 1.96 \sqrt{0.000236} )[/tex]

(0.0882 - 0.03011 , 0.0882+0.03011)

(  0.05809 , 0.1183)

Final answer:-

95% of the confidence interval for q is

The answer is B. 21Step-by-step explanation:

Answer:

The area of the figure is 36 [tex]in^2[/tex].

Step-by-step explanation:

You can cut the composite shapes into two shapes to make the calculation process easier: a triangle and a rectangle. The area of the triangle is [tex]\frac{1}{2} * 9*2=\frac{1}{2} *18=9[/tex] [tex]in^2[/tex], and the area of the rectangle is 9 * 3 = 27 [tex]in^2[/tex], so the area of the composite shape is 27 + 9 = 36 [tex]in^2[/tex].

Answer:

36in²

Step-by-step explanation:

In order to find the area of a composite shape, we must split the shape up into two regular shapes.

Thus, area of composite shape = area of triangle + area of rectangle

The area of a rectangle can simply be found my multiplying the width by the length

The rectangle shown has a length of 9 in and a width of 3 in

Hence, A = 9 * 3

9 * 3 = 27

Therefore the area of the rectangle is 27in²

The area of a triangle can be calculated by multiplying the base length by the height and then dividing the product by 2

The triangle shown has a given height of 2 in and a base length of 9 in

Thus, [tex]A=\frac{2*9}{2}[/tex]

2 * 9 = 18

18 / 2 = 9

Hence, the area of the triangle is 9 in²

Finally we add the two areas together

9 + 27 = 36

Hence, the area of the composite figure is 36in²

Answer:

0.42

Step-by-step explanation:

they are both multiples of 0.06

think of it like 6 x 6= 36 and 6 x 8 = 48

6 x 7 = 42 would be halfway

Answer:

0.42

Step-by-step explanation:

To find the half, add da numbers and divide by 2. So 0.36 and 0.48 added together is 0.84. That divided by 2 is 0.42.

I can only see that she have 5 elephants, possibly more, however it's cut off. If that's true. Then:

If she has 5 elephants (which is currently what she has the most of) and 2 zebras. She needs 4 more zebras. Then she will have 6 zebras. More then any other animal.

Answer:

assuming the elephant has the most dots, as i cant see the full picture, then she needs to collect 4 more because she has 2 already.

Step-by-step explanation:

The elephant has 5 dots

the zebra has 2 dots
