The probability of students entering the medical field is 11/50. Predict how many out of 500 will enter the field. Please enter the numerical value only
Answer:
110
Step-by-step explanation:
The probability of students entering the medical field = p = (11/50)
The number of people that'll enter the medical field out of 500 = np
n = 500
p = (11/50)
np = 500 × (11/50) = 110
Hope this helps!!!
Answer:
110 Students
Step-by-step explanation:
The probability of students entering the medical field is [tex]\dfrac{11}{50}[/tex].
In an experimental trial, this probability is referred to as the relative frequency of students entering the medical field.
Given that there are 500 students, we want to determine how many will enter the medical field.
Total Number of Trials=500We use the formula:
[tex]\text{Number of Expected Outcome}=$Relative Frequency of Outcome X Total Number of Trials$\\\\=\dfrac{11}{50}X500 \\\\=110[/tex]
Therefore, 110 students will be expected to enter the medical field.

Approximate the real zeros of f(x)= x^3 - 4x + 6 to the nearest tenth.
Please select the best answer from the choices provided
A -5
B -2
C -5.2
D -2.5
Answer:
x ≈ - 2.5; Option D
Step-by-step explanation:
Let us substitute f ( x ) with 0, as to find the " real zero " of the function;
0 = x^2 - 4x + 6, ⇒ Now find one solution for x^2 - 4x + 6 = 0, using Newton - Raphson, provided it applies an iterative process to approach one root of a function, ( x( n + 1 ) = x( n ) - ( f( x( n ) ) )/( f '( x( n ) ) ) ),
d / dx * ( x^3 - 4x + 6 ), ⇒ Apply sum / difference rule ( f ± g ) ' = f ' ± g, '
d / dx * ( x^3 ) - d / dx * ( 4x ) + d / dx * ( 6 ), ⇒ Simplify,
3x^2 - 4 + 0, 3x^2 - 4, ⇒ Compute x( n + 1 ) until Δ x( n + 1 ) < 0.000001,
x ≈ - 2.52510.....

The circles at the right are congruent. Which conclusion can you draw?
A. Angle AEB = Angle QUR
B. Angle CED = Angle SUT
C. CD = ST
D. Arc BD = Arc RT
Answer:
C. CD=ST
Step-by-step explanation:
The conclusion we can draw from the given diagram is Angle AEB = Angle QUR. The correct option is A. Angle AEB = Angle QUR
Congruent circlesFrom the question, we are to deduce which of the given options is correct
From the given information, the circles are congruent
Congruent circles have the same or equal radii
As indicated in the diagram,
Arc AB = Arc QR
Since, the radii of the two circles are equal and the arcs (arc AB and arc QR) are as well equal, their central angles must be equal
∴ Angle AEB = Angle QUR
Hence, the conclusion we can draw from the given diagram is Angle AEB = Angle QUR. The correct option is A. Angle AEB = Angle QUR

The student who traveled to 3 states visited 3 new states during a vacation. Does increasing the 3 to 6 change the median? If so, how?
Answer:
Yes, changing from 3 states to 6 states changes the median because:
- The median of the first 3 states is simply the middle-placed state of the 3 states.
- The median of 6 states is the average of the 2 middle states.
Step-by-step explanation:
Suppose the first 3 states in order are:
A, B, C.
The median of these states is simply the middle state, B.
Adding 3 new states to have:
A, B, C, D, E, F.
The median is not explicit. It is the average of the two middle states, C and D.
Average of C and D is half of the sum of C and D.
That is (C + D)/2.
Which is different from B.
Find the arc length of major arc GH. Round your answer to the nearest tenth.
Answer:
42.1 cm
Step-by-step explanation:
The length of the arc is circumference of the circle - length of minor arc GH
circumference of circle = 2 * π * r = 2 * π * 9.1 = 18.2 π cm
The length of the minor arc = angle/360 * 2 * π * r
Now this is tricky, the angle is 360-265 = 95
The length of the minor arc = 95/360 * 2 * π * 9.1 = 4.80 π
Length of major arc = 18.2 π -4.8 π = 13.4 * π = 13.4 * 22/7 = 42.11cm

What is a quadratic equation?A quadratic equation can be defined as a mathematical expression (equation) that can be used to define and represent the relationship that exists between two or more variable on a graph. In Mathematics, the standard form of a quadratic equation is given by;
ax² + bx + c = 0
The derivation of quadratic formula.Mathematically, the quadratic formula can be derived as follows:
x² + b/ax +c/a = 0
x² + b/ax = -c/a
x² + b/ax + (b/2a)² = - c/a + (b/2a)² [completing the square]
(x + b/2a)² = b²/4a² - c/a
x + b/2a = √(b²/4a² - c/a)
[tex]x = \frac{-b\; \pm \;\sqrt{b^2 - 4ac}}{2a}[/tex]
In conclusion, the step which is shown in the image above for the derivation of the quadratic formula was derived by using completing the square method.

If the quadratic model applies the function f(x) = -0.11688x² + 2.5355x + 7.0238, what is the predicted value and residual when the tree is 7 years old with a height of 19?
Answer:
predicted value = 19.04518
Residual = -0.04518
Step-by-step explanation:
Residual = y - predicted y
In this case y = 19 for a 7 year old tree.
f(7) = 19.04518
Residual = 19 - 19.04518
Residual = -0.04518

A ball is thrown into the air with an upward velocity of 13 ft/s. Its height h in feet after t seconds is given by the function h = −2t^2+ 13t + 24. In how many seconds does the ball reach its maximum height?
Answer:
3.25 seconds
Step-by-step explanation:
The maximum height will occur when the velocity of the ball reaches zero in the air.
Velocity is given as the derivative of height, dh/dt.
The equation of height given is:
[tex]h = -2t^2+ 13t + 24[/tex]
Differentiating height, h, with respect to time, t, we have:
[tex]v = dh/dt = -4t + 13[/tex]
When v = 0:
[tex]0 = -4t + 13\\\\=> 4t = 13\\\\t = 13 / 4 = 3.25 secs[/tex]
Therefore, it will take 3.25 seconds for the ball to reach maximum height.
Find the volume of a right circular cone that has a height of 10.7 in and a base with a diameter of 8.1 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
[tex] V = \pi r^2 h[/tex]
And for this case the value for the height is [tex] h = 10.7 in[/tex] the diameter is provided [tex] D = 2r = 8.1 in[/tex] so then the radius is given by:
[tex] r = \frac{D}{2}=\frac{8.1 in}{2}= 4.05 in[/tex]
