30g serving of cereal has 0.5 grams of salt how much salt would that be in milligrams

A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it

emmainna [20.7K]

So 80% of 15 games won equal 12 games won and 3 lost. This is because 15/10 = 1.5 and 1.5 x 8 =12.
For 30, you do the exact same thing but with 90% instead. 30/10 = 3. 3 x 9 = 27.
So they need to have won 27 games to get a 90% winning percentage out of 30 games.
But since the question asks how many MORE games they need to play, it'll be 27-12 = 15.
So they need to win 15 more games to get a 90% winning percentage

F(x) = -322 Find f(-2)

serg [7]

Answer:

f ( - 2 ) = - 12

Step-by-step explanation:

f ( - 2 ) = - 3 ( -2 )^2

then you do the exponent first so

- 3 ( 4 )

now you multpily the - 3 and 4

you get - 12

Determine the margin of error, m , of a 99% confidence interval for the mean IQ score of all students with the disorder. Assume

madreJ [45]

Answer:

E= 6.45

standard deviation is σ = 15,

The critical value is z(α/2) = 2.58.

Step-by-step explanation:

Margin error is the value that is lie above and below the sample.It gives percentage of numbers.Its is the product of critical value standard deviation and standard error of statistic.

General formula for the margin of error is

Margin of error = critical value × standard error of statistic

= $z \alpha /2$ × σ √n

z-value from two tailed is listed below:

From the table of standard normal distribution, probability value of 0.10.

row and column values gives the area to the two tail of z.

The positive z value is 2.58.

standard deviation is σ = 15,

The critical value is z(α/2) = 2.58.

after putting these vales we obtain the margin of error value that is

E= 6.45

Find the radius of a circle in which an inscribed square has a side of 8 inches.

Semenov [28]

Answer:

$4\sqrt{2} =5.66$

Step-by-step explanation:

The square is in the circle, so the diameter is the diagonal line of the square. This divides the square into two right triangles.

Two sides of the right triangle equal 8. This qualifies it as a special right triangle. This triangle has two sides that = x (in this case 8) and the hypotenuse is $x\sqrt{2}$ .

Substitute 8 in for x.

$8\sqrt{2}$ is the diameter, so we divide in half to get the radius = $4\sqrt{2}$
