Landon owns 16 baseball cards, which is 4 times as many as Phillip owns.
The equation 4p=16 represents this situation where p is the number of baseball cards Phillip owns.
Which number line represents the solution to the equation?
Answer:
B
Step-by-step explanation:
i'm probably wrong but based on the information they give you the most likely answer has to be B. ok- well if you think abt it landon has 16 cards and that's 4 times as many as phillip has. so, phillip's cards could range anywhere between 4 and 16-
sorry if i'm incorrect :/ hope you get a good score or whatever tho
The age of trees in a forest is known to be approximately normal with an average age of 40 years and a standard deviation of 10 years. About ____ of the trees have ages between 10 years and 70 years.
Answer:
Not 95%
Step-by-step explanation:
The normal distribution is also known as the Gaussian distribution. About 99.7% of the trees have ages between 10 years and 70 years.
What is Normal Distribution?The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Given that the age of the tree is normally distributed. Also, the following details are known,
Standard Deviation, σ = 10 years
Mean, μ = 40
Now, the z-score and the p-values for the value of 70 and 10 can be written as,
Z = (X-μ)/σ
Z = (70 - 40)/10
Z = 3
The p-value for z-score of 3 is 0.9987.
Z = (X-μ)/σ
Z = (10 - 40)/10
Z = -3
The p-value for z-score of -3 is 0.0013.
Further, the percentage of the trees have ages between 10 years and 70 years is,
Percentage = 0.9987 - 0.0013
= 0.9974
= 99.7%
Hence, About 99.7% of the trees have ages between 10 years and 70 years.

Answer:
B and D are correct.
Step-by-step explanation:
To find the area of a rectangle, simply multiply its length by its width. In this case, the length of the rectangle is [tex]5[/tex] m and the width of the rectangle is [tex]3[/tex] m, so its area must be [tex]5*3=15[/tex] square meters.
To find the area of a triangle, divide the product of the triangle's base and height by [tex]2[/tex]. As an algebraic expression, that would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] and [tex]h[/tex] are the triangle's base and height, respectively. In this case, [tex]b=6[/tex] and [tex]h=5[/tex], so the triangle's area is [tex]\frac{6*5}{2}=15[/tex] square meters.
Now, let's look at the statements.
A: The triangle's area is [tex]15[/tex] square meters, not [tex]30[/tex], so A is incorrect.
B: The rectangle's area is [tex]15[/tex] square meters and the triangle's area is also [tex]15[/tex] square meters. Because the two figures have the same areas, their areas are equal, so B is correct.
C: We've already established that the two figures have equal areas, so one can't have a greater area than the other. Therefore, C is incorrect.
D: The rectangle's area is indeed [tex]15[/tex] square meters, so D is correct.
Hope this helps!
Answer:
B is correct, and D is correct
if you multiply 3 times 5 you get 15 m which is the area for the rectangle, then you have to find the area for the triangle, which you would have to multiply 6 times 5 which you get 30, then divide 30 by 2, which would be 15!

To find the constant of proportionality, all we have to do is divide any value of [tex]y[/tex] by its corresponding value of [tex]x[/tex]. Let's take the values in the first row of the table.

Answer:
Step-by-step explanation:
To get the area of the cone we need to find the radius first.
tan 70=r/12
r=12tan 70
area of a circle is given by:
A=πr²
thus the area of the ground covered by the tent will be:
A=π(12tan70)²
The answer is
A] A=π(12tan70°)²

The height, h, of a plant (in inches) w weeks since it was planted is represented by the equations h=3w+3. How many weeks will it takes the plant to reach one foot.
Answer: 3 weeks
Step-by-step explanation:
We have to note firstly that 12 inches = 1 foot.
The equation given to represent the height in the question, h = 3w + 3.
The number of weeks that it will take the plant to reach one foot will then be:
h = 3w + 3
12 = 3w + 3
3w = 12 - 3
3w = 9
w = 9/3
w = 3
It'll take 3 weeks
