A coin is tossed and a spinner numbered 1 to 7 is spun. What is the probability of getting an odd number and heads

Your answer is 4/14 or 2/7. There are two possibilities when you flip a coin, heads or tails. Then for the spinner there are 7. Multiply them by each other to get the total number of outcomes of the situation of 14. Then there are only 4 odd numbers from 1-7. This means that you would only be able to get an odd number and heads 4 times.

Hope this helped!

The area of a rectangle is 44 square units. Its length measures 4 units. Find the length of its diagonal. Round to the nearest t

NikAS [45]

Answer:

√(137)

Step-by-step explanation:

First, you will need to find the other side length.....then you can use the Pythagorean Theorem to find the diagonal:

L x W = 44

4 x W = 44

W =11

Now the Pythag, Theorem:

diagonal^2 = 4^2 + 11^2

d^2 = 16+121

d^2 = 137

d = √(137)

The area of a rectangle is 28square miles. The length is 7 miles.

Masja [62]

Area=length times width
area=28
length=7

28=7 times width
divide both sides by 7
4=width

the width is 4 miles
and perimiter is 22mi

Suppose 2' is a normally distributed random variable with ft = 10.3 and 0 = 3.8. For the following probability,draw an appropria

TiliK225 [7]

GIVEN

The following values are given:

$\begin{gathered} \mu=10.3 \\ \sigma=3.8 \end{gathered}$

SOLUTION

The z-score for the x values 9 and 14 can be calculated using the formula:

$z=\frac{x-\mu}{\sigma}$

For x = 9:

$\begin{gathered} z=\frac{9-10.3}{3.8} \\ z=-0.34 \end{gathered}$

For x = 14:

$\begin{gathered} z=\frac{14-10.3}{3.8} \\ z=0.97 \end{gathered}$

The probability can be calculated as follows:

$P(9\le x\le14)=Pr(-0.34The region that represents the solution is shown below:Therefore, the probability is given to be:[tex]P(9\le x\le14)=0.4671$

The probability is 0.4671.

What is the median of the data set?

cluponka [151]

Answer: 85.5

Step-by-step explanation:

There are 22 data points in the data set.

We can find the median by looking at the 11th and 12th scores, and averaging them.

The 11th score is 85

The 12th score is 86

The average of the two is 85.5

Hence the answer is 85.5
