Suppose that prior to conducting a coin-flipping experiment, we suspect that the coin is fair. How many times would we have to f

BabaBlast [244]

Answer:

153 times

Step-by-step explanation:

We have to flip the coin in order to obtain a 95.8% confidence interval of width of at most .14

Width = 0.14

ME = $\frac{width}{2}$

ME = $\frac{0.14}{2}$

ME = $0.07$

$ME\geq z \times \sqrt{\frac{\widecap{p}(1-\widecap{p})}{n}}$

use p = 0.5

z at 95.8% is 1.727(using calculator)

$0.07 \geq 1.727 \times \sqrt{\frac{0.5(1-0.5)}{n}}$

$\frac{0.07}{1.727}\geq sqrt{\frac{0.5(1-0.5)}{n}}$

$(\frac{0.07}{1.727})^2 \geq \frac{0.5(1-0.5)}{n}$

$n \geq \frac{0.5(1-0.5)}{(\frac{0.07}{1.727})^2}$

$n \geq 152.169$

So, Option B is true

Hence we have to flip 153 times the coin in order to obtain a 95.8% confidence interval of width of at most .14 for the probability of flipping a head

Answer: Mary makes $1160, Steven makes $142.50

Step-by-step explanation:

Facts

MARY

8% commision on everything she sells

She sells a car for $14,500

The first question about Mary asks how much commision she makes. To find that, lets find 8% of 14,500

8% of 14,500= 0.08x14,500= 1160

Therefore, Mary makes $1,160 in commision.

STEVEN

Facts

He makes 15% in commision for the supplies he sells

He sells $950 in supplies

Money made =?

15% of 950=0.15x950=$142.50

HELP!!!!!!!!!! WILL GIVE BRAINLY!!!!!!!

atroni [7]

Answer:

141 $in^{2}$

Step-by-step explanation:

Area of a trapezium = $\frac{h}{2}$ (a + b)

h = height

a and b = upper and and lower lengths

Area of a trapezium = $\frac{9}{2}$ (10 + 16)

= $\frac{9}{2}$ × 26

= 117 $in^{2}$

Area of a triangle = $\frac{1}{2}$ × base × height

= $\frac{1}{2}$ × 6 × 8

= $\frac{1}{2}$ × 48

= 24 $in^{2}$

Total area = Sum of the areas of both the shapes

= 117 + 24

= 141 $in^{2}$
