Suppose you have a bag of marbles. You know that there are 10 marbles in the bag,
but you do not know what colors they are. You select a marble 40 times, each time
recording its color before putting it back. In 8 out of 40 trials you select a purple
marble.
Based on the data, how many purple marbles do you estimate are in the bag? Explain
your prediction
Answers
Answer:
8 out of 40 trials- 8/40
simplify that and it becomes 1/5
1/5 of 10 is 2
so, I'd estimate there are 2 purple marbles.
A wire makes a 70 degrees angle with the ground and is attached to the top of a 50 ft. antenna. How long is the wire?
Answers
Answer:
53.2 ft
Step-by-step explanation:
A wire makes a 70 degrees angle with the ground and is attached to the top of a 50 ft. antenna. How long is the wire?
We solve the above question using the Trigonometric function of Sine
sin theta = Opposite/Hypotenuse
Theta = 70°
Hypotenuse = x = Length of the wire
Opposite = 50ft antenna
Hence,
sin 70 = 50/x
Cross Multiply
50 = sin 70 × x
x = 50/sin 70
x = 53.208888624 ft
Approximately x = 53.2 ft
The length of the wire is 53.2 ft
A pyramid has a rectangular base of dimensions 15 cm and w cm. Given that its height and volume are 18 cm and 826 cm3 respectively, find the value of w.
Answers
Answer:
9.18 cm
Step-by-step explanation:
A pyramid is a three-dimensional object. The base of a pyramid is a polygon. the top and the base of a polygon forms a triangle.
for a rectangular pyramid, the base is a rectangle
The volume of a pyramid = 1/3 × (area of the rectangle x height)
Area of a rectangle = length x width
15 x w = 15w cm²
826 = 1/3 x (15w x 18)
multiply both sides of the equation by 3
15w x 18 = 2478
Divide both sides of the equation by 15 x 18
w = 9.18 cm
divide both sides by 10

Answers
Answer:
No, you would graph the y-intercept, you do not graph the m-value (slope). The slope value is the rate that the y-value increases per unit of x. This is how you graph your line from the y-intercept
Answer:
No you are incorrect. The correct answer is (y - intercept) b = -4
Step-by-step explanation:
You need to plot the y - intercept first so that you can create the line using the slope starting from the y - intercept. You can't plot the line unless you first plot a point on the line which would be the y - intercept or -4 THEN from there you use the slope to create the line.

angle pairs: correctEF/HI = EG/HJ = FG/IJStep-by-step explanation:
As with the angle pairs, use the corresponding vertices to name corresponding segments.
As is done here, I find it convenient to list the vertices vertically in the order shown in the similarity statement.
∠E ≅ ∠H∠F ≅ ∠I∠G ≅ ∠JThis can make it easier to identify the corresponding vertices used for naming segments.
__
Moving on the the extended proportion, ...
The denominator HI uses the first two vertices, with E corresponding to H and F corresponding to I. The appropriate ratio is ...
EF/HI
The denominator HJ uses the 1st and 3rd vertices, with E (still) corresponding to H and J corresponding to G. The appropriate ratio is ...
EG/HJ
Similar thinking is used to identify the last ratio:
FG/IJ
Then the extended proportion is ...
EF/HI = EG/HJ = FG/IJ

A parallelogram has sides 17.3 m and 43.4 m long. The height corresponding to the 17.3-m base is 8.7 m. Find the height, to the nearest tenth of a meter, corresponding to the 43.4-m base.
Answers
Answer:
3.5m
Step-by-step explanation:
A parallelogram has sides 17.3 m and 43.4 m long.
The height corresponding to the 17.3-m base is 8.7 m.
The area of a parallelogram = base × height
= 8.7m × 17.3m
= 150.51m²
Both parallelograms have the same area
Hence, the height, to the nearest tenth of a meter, corresponding to the 43.4-m base is calculated as:
= 150.51m²/43.4m
= 3.4679723502m
Approximately = 3.5m
