To fine the mean for a first add up all the players heights then divide by the number of players.

Mean=(198+199+200+201+202)÷5
=1000÷5
=200

The answer to a is 200

For question be were gonna say for now that the height of our new player is represented by x. So we know that together there is 6 players and we know our answer so it should look something like this

201= (199+198+199+200+201+202+x) ÷ 6
201=1000+x ÷ 6
Then Im going to multiply 201 by 6 to get rid of the 6 on the other side.
1206=1000+x
Then I’m going to subtract 1000 from both sides to get x by itself
206=x

So the new players height is 206 .

Answer: 83

Step-by-step explanation:

The confidence interval for population mean is given by :-

$\overline{x}\pm E$

Given : The student obtained the following 95% confidence interval (in grams) for the population mean, (862,1028).

Here,

Lower limit of the confidence interval : $\overline{x}-E=862$ (1)

Upper limit of the confidence interval : $\overline{x}+E=1028$ (2)

Subtracting (1) from (2) , we get

$2E=166\\\\\Rightarrow\ E=\dfrac{166}{2}=83$

Hence, the margin of error = 83

y=2x

switch x and y

x=2y

solve for y

x/2 =y

this is the same as g(x)

Find the value of b. Round your answer to the nearest tenth.

Answer:

Side CA = 7.8

Step-by-step explanation:

Given:

Acute angled $\triangle ABC$ .

$\angle B =40^\circ$

AB = 10

BC = 12

We can use cosine rule here to find the side AC = b

Formula for cosine rule:

$cos B = \dfrac{a^{2}+c^{2}-b^{2}}{2ac}$

Where

a is the side opposite to $\angle A$

b is the side opposite to $\angle B$

c is the side opposite to $\angle C$

$cos 40 = \dfrac{12^{2}+10^{2}-b^{2}}{2\times 12\times 10}\\\Rightarrow cos 40 = \dfrac{144+100-b^{2}}{240}\\\Rightarrow 0.77 = \dfrac{244-b^{2}}{240}\\\Rightarrow 244-b^{2} = 0.77 \times 240\\\Rightarrow 244-b^{2} = 183.85\\\Rightarrow 244-183.85 = b^{2}\\\Rightarrow b^2 = 60.15\\\Rightarrow b = 7.76$

To the nearest tenth b = 7.8
