#17. The height, H metres, of a certain species of Fir
tree can be estimated from the formula.
h= 35d , where d metres is the diameter at the
base. use the formula to determine the approximate
height of a fir tree with base diameter 3.2 m.
Answer:
The approximated height of the tree is of 112 meters.
Step-by-step explanation:
The height of a tree with a base diameter of d meters is approximated by the following formula:
[tex]h = 35d[/tex]
In this question:
Base diameter of 3.2m, so [tex]d = 3.2[/tex], and the height is in meters.
[tex]h = 35d = 35(3.2) = 112[/tex]
The approximated height of the tree is of 112 meters.
Answer:
The answer actually is 76m

Step-by-step explanation:
use the bar diagram to help you solve the equation 4x-12=16.
Answer:
x = 7
Step-by-step explanation:
4x−12=16
Step 1: Add 12 to both sides.
4x−12+12=16+12
4x=28
Step 2: Divide both sides by 4.
4x/4 = 28/4 = 7
x=7
The weight in gram of 15 packets of sweets are: 55.0,55.3,55.3,55.3,55.5,55.6,55.8,55.9,56.1,56.2,56.2,56.4,56.7,56.7,56.8. Write down the value of the medium and quartiles
Given:
The weight in gram of 15 packets of sweets are: 55.0, 55.3, 55.3, 55.3, 55.5, 55.6, 55.8, 55.9, 56.1, 56.2, 56.2, 56.4, 56.7, 56.7, 56.8.
To find:
The value of the median and quartiles.
Solution:
We have,
55.0, 55.3, 55.3, 55.3, 55.5, 55.6, 55.8, 55.9, 56.1, 56.2, 56.2, 56.4, 56.7, 56.7, 56.8
Divide the data set in two equal parts.
(55.0, 55.3, 55.3, 55.3, 55.5, 55.6, 55.8), 55.9, (56.1, 56.2, 56.2, 56.4, 56.7, 56.7, 56.8)
Divide each parenthesis in two equal parts.
(55.0, 55.3, 55.3), 55.3, (55.5, 55.6, 55.8), 55.9, (56.1, 56.2, 56.2), 56.4, (56.7, 56.7, 56.8)
Now,
First quartile = 55.3
Second quartile = Median = 55.9
Third quartile = 56.4
Therefore, the median is 55.9 and the three quartiles are 55.3, 55.9, 56.4 respectively.
9.Patients who are addicted to cocaine are sometimes using the drug to combat
depression. As such, sometimes addicts are given antidepressant medications to
prevent relapse. A three-year study compared the effects of two such medications,
lithium and desipramine, along with a placebo for 72 cocaine users wishing to break
the habit. The patients were put into 3 groups of 24, and given 1 of the 3 treatments at
random. This two-way table illustrates the results.
Treatment Relapse No relapse Total
Desipramine 10 14 24
Lithium 18 6 24
Placebo 20 4 24
Total 48 24 72
According to the table, 48 of the addicts relapsed regardless of the treatment given.
This number is an example of a
A. relative frequency
B. marginal frequency.
C. conditional relative frequency.
D. joint frequency

Write an equation for the function whose graph is described.
The shape of f(x) = |x|, but shifted 19 units up and then reflected in the x-axis
Answer:
f(x)=-|x|+19
Step-by-step explanation:
so shifted 19 units up means
abosolute value of x + 19
and reflected in the x axis means that you have to put the - before the abosolute value.
so -|x|+19

Step-by-step explanation:
Consider a 95 percent confidence interval constructed for the difference between two population
proportions PR and Ps. The interval for PR - Ps is given as (-0.05, 0.15). Which of the following is an
appropriate interpretation of the confidence level?
In repeated random sampling with the same sample size, êr - Ộs will be contained in
the interval approximately 95 percent of the time.
In repeated random sampling with the same sample size, PR will be contained in the
interval approximately 95 percent of the time.
In repeated random sampling with the same sample size, Ôr will be contained in the
interval approximately 95 percent of the time.
The probability is 0.95 that the difference in the sample proportions PR - Ổs is between
-0.05 and 0.15
In repeated random sampling with the same sample size, approximately 95 percent of the
intervals will capture the difference in population proportions, PR - Ps.
Answer:
E
Step-by-step explanation:
In repeated random sampling with the same sample size, approximately 95 percent of the intervals will capture the difference in population proportions, PR - Ps.
find the x (please help lol)
Answer:
x = 23.5
Step-by-step explanation:
x is the midsegment theorem of the trapezoid given.
Based on the midsegment theorem of a trapezoid, thus:
x = (7 + 40)/2
x = 47/2
x = 23.5

Step-by-step explanation:
For this problem find the area for the three individual segment then add them together.
Step 1: Find area of the rectangle
formula for area of a rectangle: bxh
b-base
h-height
3x6=18
Step #2: Find area of the triangle
Formula for area of a triangle:[tex]\frac{1}{2} bxh[/tex]
b-base
h-height
[tex]\frac{1}{2} (3x3)[/tex]=1/2(9)=4.5
Step #3: Find the area of the triangles total
Because the two triangles have the same area you can just multiply the area of one of the triangles by 2
4.5x2=9
Step #4: Add all the areas together

Find the x and y intercepts Y-2xy+4x=1
Answer:
[tex]x = \frac{1}{4}[/tex]
[tex]y= 1[/tex]
Step-by-step explanation:
Given
[tex]y - 2xy + 4x = 1[/tex]
Solving (a) The x intercept
Let y = 0
[tex]y - 2xy + 4x = 1[/tex]
[tex]0 - 2x*0 + 4x = 1[/tex]
[tex]0 - 0 + 4 x = 1[/tex]
[tex]4x = 1[/tex]
Divide both sides by 4
[tex]x = \frac{1}{4}[/tex]
Let x = 0
[tex]y - 2xy + 4x = 1[/tex]
[tex]y - 2y * 0 + 4*0 = 1[/tex]
[tex]y - 0 + 0 = 1\\[/tex]
[tex]y= 1[/tex]
