the answer choices are
a. 32m
b. 225 m
c. 5 m
d. 15 m
Answer:
d. 15 m
Step-by-step explanation:
hypotenuse (h) = 25 m
base (b) = 20 m
perpendicular (p) = ?
By using Pythagoras theorem we get
p = √h² - b²
= √ 25² - 20²
= √ 225
= √ 15²
= 15 m
Hope it will help :)
Answer:
15
Step-by-step explanation:
according to pythagoras:
25^2 = 20^2 + 15^2
If a fair die is rolled 7 times, what is the probability, rounded to the nearest thousandth, of getting at most 2 twos?
Answer:
0.904
Step-by-step explanation:
Using the binomial distribution, it is found that there is a 0.905 = 90.5% probability of getting at most 2 twos.
For each time the die is rolled, there are only two possible outcomes, either the result is a 2, or it is not. The result on a roll is independent of any other roll, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.In this problem:
The die is rolled 7 times, hence [tex]n = 7[/tex].One out of the 6 sides is a 2, hence [tex]p = \frac{1}{6} = 0.1667[/tex]The probability is:
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]
Hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{7,0}.(0.1667)^{0}.(0.8333)^{7} = 0.279[/tex]
[tex]P(X = 1) = C_{7,1}.(0.1667)^{1}.(0.8333)^{6} = 0.391[/tex]
[tex]P(X = 2) = C_{7,2}.(0.1667)^{2}.(0.8333)^{5} = 0.235[/tex]
Then:
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.279 + 0.391 + 0.235 = 0.905[/tex]
0.905 = 90.5% probability of getting at most 2 twos.

if you where asked to solve a system of linear equations using the substitution method, what form would one or both of the equations start as that would make the problem the simplest?
A. point-slope form
B. standard form
C. slope-intercept form
D. point-intercept form
Answer:
It's A
Step-by-step explanation:
In general, the equation in point-slope form will give an expression that can substitute for "y", as that form is ...
y = [something]
_____
In specific instances, the other forms of the linear equations may work, but that is not guaranteed.
Use the FOIL method to check your answer from part A.

5) £940 increased by 8%
Answer:
£1015.2
Step-by-step explanation:
We need to find £940 increased by 8%. It can be calculated as follows :
[tex]940+940\times \dfrac{8}{100}\\\\=940+75.2\\\\=\$1015.2[/tex]
It means if £940 increased by 8%, then the answer is equal to £1015.2.
Graph y=1.4xy=1.4xy, equals, 1, point, 4, x. plz help its not too late plz
Replace x with any number and solve for Y.
Do this at least twice to get 2 points.
Place these points on the graph and draw a line through them.
See attached graph.
Let x = 2
y = 1.4(2)
y = 2.8
First point = (2,2.8)
Let x = 5
y = 1.4(5)
y = 7
Second point = (5,7)
The y-intercept is zero, that means the line is passing through origin.
What is the equation of line?The equation of line is given as
y = mx + c
Where m is the slope and c is the y-intercept.
The equation is given below.
y = 1.4x
In the above equation, y-intercept is not there, which means the line is passing through origin.

both line and rotational symmetry
none of the above
Answer:
B. rotational symmetry onlyStep-by-step explanation:
Line symmetry is when the line acts like a mirror. We don't have such a symmetry here.
The figure has rotational symmetry only, if you rotate it about its center it will map to itself every 180 degrees.

Suppose there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 58.3°F, what will be the temperature when the plane reaches an altitude of 2,000 ft?
Answer: 55.1°F
Step-by-step explanation:
We are informed that there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky, if the plane reaches an altitude of 2,000ft, the drop in temperature will be:
= 1.6° × 2
= 3.2°F
If the temperature on the ground is 58.3°F, then the temperature when the plane reaches an altitude of 2,000 ft will be:
= 58.3°F - 3.2°F
= 55.1°F

If each box of cookies weighs 1 pound, what is the range of the total weight of her wagon while she is delivering cookies?
Enter the correct answers in the boxes.

Answer:
0-108
Step-by-step explanation:
I have the same assignment and got it while working on it
you have to say from either 0 or 12 pounds to 108 as you have to multiply 12 x 9.
The range of the total weight of her wagon while she is delivering cookies is 12 pounds to 21 pounds.
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Given:
Spiral Review Gretchen is delivering boxes of cookies to her neighbors. Her wagon itself weighs 12 pounds when empty and will hold up to 9 boxes.
Each box of cookies weighs 1 pound.
Weight of 9 boxes = 9 pounds.
So, the range,
= 12 pounds to 12 + 9 pounds
= 12 pounds to 21 pounds.
Therefore, the range is 12 pounds to 21 pounds.
