Answer: The outcome of spinning a spinner with five equal outcomes

Step-by-step explanation:

The discrete random variable that could be represented by a  probability histogram whose bars are all the same height is;

Option C; The outcomes of spinning a spinner with five equal sections

The probability histogram is a type of histogram whereby the height of each bar shows the true probability of each outcome of a specific number of trials.

Now, let us look at the options;

Option A; This cannot be represented by a probability histogram because it doesn't show probability.

Option B; This cannot be represented by a probability histogram because it shows just ages and doesn't show probability.

Option C; This can be be represented by a  probability histogram because it shows the probability of each outcome of spinning five equal sections.

Option D; This cannot be represented by a probability histogram because it should show the probability of each outcome and not just that of one weighted die.

Answer:

a) 63°

b) 600ft

Step-by-step explanation:

To solve the above question, we would be using Trigonometric function

a) Find (to the nearest whole degree)

the angle with the horizontal at

which the balloon rises.

This above question a is a right angled triangle that is solved for using Trigonometric function of tan

From the question, we told that,

Vertical distance ( opposite side) = 10 feet

Horizontal distance ( adjacent side) = 5 feet.

Tan θ = opposite side/ adjacent side

Tan θ = 10/5

Tan θ = 2

θ = arc tan (2) or tan -¹(2)

θ = 63.434948823°

θ = 63°

The angle with the horizontal at

which the balloon rises to the nearest whole degree is 63°

b) find (to the nearest 10 feet) its

distance from the starting point

after one minute.​

Distance = Speed × time

Time is given in the question as 1 minute

We would convert it to seconds = 60 seconds

We are told in the question that the balloon rises vertically at the speed of 10ft/s

Distance = 10ft/s × 60seconds

Distance from the starting point per minute = 600ft

Answer:

Hai

Yes, its true.

because in 21, there are 4 times of 5 and we have left 1 number..

you can multiply -4 with 5 and add the number of the denominator (1)

i wanna give one more example because couldnt explained well.

Step-by-step explanation:

1 . Consider the Triangle Inequality Theorem, as to solve for the length of the third side;

[tex]Triangle Inequality Theorem -\\\\| a - b | < c < a + b,\\| c - a | < b < c + a,\\| c - b | < a < c + b,\\\\Say, a = 11 cm, b = 9 cm, c = 20 -\\\\11 - 9 < 20 < 11 + 9,\\20 - 11 < 9 < 20 + 11,\\20 - 9 < 11 < 20 + 9\\\\As 20 = 20, not 20 < 20 -\\Conclusion ; Length of Third Side = 15 cm[/tex]

2 . Consider c - commission $;

Answer:

36.5 degrees

Step-by-step explanation:

angle abc is a straight angle ( which is 180 degrees )therefore:

angle ABD + angle DBC = angle ABC

substituting the given measurements gives us=

3x + 22 + x - 4 = 180

4x = 162

x = 40.5

the question asks us to find measure of angle DBC so we substitute x which =

measure DBC = x - 4

measure DBC = 40.5 - 4

measure DBC = 36.5 degrees

Answer:

10100=15700(1-0.075)^x

10100=15700(0.925)^x

divide both sides by 15700

0.925^x=101/157

convert decimal

(37/40)^x=101/157

take the log

x= log 37/40 (101/157)

x= 5.65824

Answer:

6.03

Step-by-step explanation:

'6' would be a whole number. When stating decimals, you would say the whole numbers before 'and'.

For example: 5.6 would be 'five and six tenths'. Note that five is before 'and'.

'Three hundredths' would be .03.

Therefore:

"Six and three hundredths" would be '6.03'.

Answer: 97.6 in3

Step-by-step explanation:

Hi, to answer this question we have to calculate the volume of the cylinder and subtract the volume of the cone:

Volume of a cylinder: π (diameter /2) ^2 (height)

Vcy = π (4 /2) ^2 (8) = π (2) ^2 (8) =100.5 in3

Volume of a cone = 1/3 π (diameter /2) ^2 (height)

V Co = 1/3 π (4/2) ^2 (0.7) = 1/3 π (2) ^2 (0.7) = 2.9 in3

Finally:

Volume of the cylinder - volume of the cone = 100.5-2.9 = 97.6 in3
