Imagine negatives as a form of debt, you start out owing someone 3 dollars, (-3); and then you borrow 5 more from them, (-5), add up the total amount of money you owe, which equals (-8). Using a number line, place a dot over where negative 5 is located, before moving back 3 steps to where negative 8 is located. This will give you your problem and answer, (-5)+(-3)=(-8)

PROBLEM SOLVING Scientists conducted aerial surveys of a seal sanctuary and recorded the number x of seals they observed during
Akimi4 [234]

Answer:

Probability that at most 50 seals were observed during a randomly chosen survey is 0.0516.

Step-by-step explanation:

We are given that Scientists conducted aerial surveys of a seal sanctuary and recorded the number x of seals they observed during each  survey.

The numbers of seals observed were normally distributed with a mean of 73 seals and a standard deviation of 14.1 seals.

Let X = <u><em>numbers of seals observed</em></u>

The z score probability distribution for normal distribution is given by;

                             Z  =  \frac{X-\mu}{\sigma}  ~ N(0,1)

where, \mu = population mean numbers of seals = 73

            \sigma = standard deviation = 14.1

Now, the probability that at most 50 seals were observed during a randomly chosen survey is given by = P(X \leq 50 seals)

            P(X \leq 50) = P( \frac{X-\mu}{\sigma} \leq \frac{50-73}{14.1} ) = P(Z \leq -1.63) = 1 - P(Z < 1.63)    

                                                          = 1 - 0.94845 = <u>0.0516</u>

The above probability is calculated by looking at the value of x = 1.63 in the z table which has an area of 0.94845.

Can anyone help me with this. It asks to solve and check your answer.
Katarina [22]
4m -21 = 3(5m - 1) 
4m - 21 = 15m - 3
15m - 4m = -21 + 3
11m = -18
m = -18/11

To check: 
LHS → 4 (-18/11)  -21 = - 303/11
RHS → 3( 5(-18/11) - 1) = -303/11
LHS = RHS (The answer is right)

What is the relationship between mass, density and volume? Provide and example that involves calculating population density.
Ymorist [56]

Answer:

Density is directly related to the mass and the volume. In fact, it tells us of the exact relationship between the two. To find an object's density, we take its mass and divide it by its volume. If the mass has a large volume, but a small mass it would be said to have a low density.

Use the graphic organizer to explain different ways to represent data.
AnnZ [28]

Check below, please.

1) Let's fill in that graphic organizer, considering the following

Dot Plot

Characteristics

This is represented by dots above the axis. These dots stands for the frequency of each data value.

Representation

We can represent them by:

Visual:

2) Now, let's proceed with the Histogram

Characteristics

A Histogram has much resemblance to a bar chart, the frequencies of each data point are represented by bars coming from the x-axis.

Representation

Notice that the y-axis marks the

frequency of each data point on the x-axis

Visual:

3) Box Plot or Box and Whiskers

This graphical representation

Representation:

Literally, in this graph, we have a box (indicating the Q1, Q2, and Q3) ie. the quartiles, and a line "the whiskers" for the outliers.
