Ricky made approximately 4 goal points for every 7 of his shots on goal. What is the probability that Ricky would make 2 goal points on two shots in a row during the season?
Given:
Ricky made approximately 4 goal points for every 7 of his shots on goal.
To find:
The probability that Ricky would make 2 goal points on two shots in a row during the season.
Solution:
Using the given information, the probability of a goal point on one shot is:
[tex]P(one\ goal)=\dfrac{4}{7}[/tex]
We need to find the probability that Ricky would make 2 goal points on two shots in a row during the season.
Since the both shots are independent events therefore,
[tex]P(Two\ goals)=P(one\ goal)\times P(one\ goal)[/tex]
[tex]P(Two\ goals)=\dfrac{4}{7}\times \dfrac{4}{7}[/tex]
[tex]P(Two\ goals)=\dfrac{16}{49}[/tex]
Therefore, the required probability is [tex]\dfrac{16}{49}[/tex].

a click beetle abruptly releases elastic energy stored in its body to launch itself into the air. the function h(t)=-16t^2+12t represents the height h (in feet) of the click beetle t seconds after launching. the height of a second click beetle t seconds after launching is shown in the graph. which click beetle went higher?
Answer:
The first click beetle reaches a maximum height of 2.25 feet. From the graph, you can see that the second click beetle reaches a maxium height of between 1.5 and 1.6 feet. So, the first click beetle went higher.
A beetle reaches a maximum height of 2.25 meters after 2,25 seconds
How to determine the maximum height?The function is given as:
h(t)=-16t^2+12t
Differentiate
h'(t)= -32t + 12
Set to 0
-32t + 12 = 0
Add 32t to both sides
32t = 12
Divide both sides by 32
t = 0.375
Substitute t = 0.375 in h(t)
h(0.375) = -16 * 0.375^2 + 12 * 0.375
Evaluate
h(0.375) = 2.25
The above means that a beetle reaches a maximum height of 2.25 meters after 2,25 seconds

Answer:
25 π /12 radians
Step-by-step explanation:
To convert degrees to radians, multiply by π /180 , since a full circle is
360 or 2 π radians.
Cancel the common factor of 15
Factor 15 out of 375

What is the measure of the missing exterior angle, in degrees?
Answer:
exterior angle is equal to the sum of two interior opposite angle
?=53+53=106°
missing exterior angle =106°
The measure of the exterior angle is 106°.
What is an exterior angle?Exterior angles are angles that are parallel to the inner angles of a polygon but lie on the outside of it.
Given that, a triangle has two interior angles 53° and 53° and an exterior angle x,
Since, we know that, sum of opposite two interior angles of a triangle is equal to measure of exterior angle.
Therefore,
53° + 53° = x
x = 106°
Hence, the exterior angle is 106°

The equation P=2(l+w) gives the perimeter P of a rectangle, where l is the length and w is the width. Solve this equation for w.
Answer: P = 2(L + W) distribute the 2
P = 2L + 2W subtract 2L from both sides
P - 2L = 2W divide both sidesby 2
(P - 2L)/2 = W

By how much would the quantity of labor demanded decrease if a minimum wage hike raised prevailing wages from $8 to $10 an hour and if the elasticity of labor demand were 0.40?
Answer:
it would decrease by 10%
Step-by-step explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
percentage change in price = ($10 - $8) / $8 = 0.25 x 100 = 25%
0.4 = percentage change in quantity demanded / 25%
percentage change in quantity demanded = 25% x 0.4 = 10%

To find x we have to basically do pythagoream theorem twice. Both the traingles share the same long side. The find the long side of the top traingle do, [tex]a^{2} +16^{2} =25^{2}[/tex], and we find the long side to be [tex]\sqrt{369}[/tex]. Using this we now plug it into the pythagoream theorem for the bottom triangle. [tex]\sqrt{369} ^{2} +x^{2} =22^{2}[/tex], and doing this out we find that x=[tex]\sqrt{115}[/tex] or about 10.7.

When a quadratic equation is in the form [tex]y=a(x-h)^2+k[/tex] (vertex form):
The x-coordinate can be found by identifying which value makes [tex](x-h)^2[/tex] equal 0The y-coordinate can be found by identifying the k value (y=k)Therefore, if the vertex of the function is at (2,-3), h needs to be 2 for [tex](x-h)^2[/tex] to equal 0 and k needs to be -3.

Melanie invested $3800 in an account paying in interest rate of 2 3/8% compounded quarterly Sebastian invested $3800 in an account paying in interest rate of 2 3/4% compounded monthly after 16 years how much more money with Sebastian have in his account then Melanie to the nearest dollar
Answer:
$317
Step-by-step explanation:
Formula for compound interest is;
A = P(1 + (r/n))^(nt)
For melanie;
P = $3800
r = 2⅜% = 0.02375
n = 12/4 = 3
t = 16 years
Thus;
A = 3800(1 + (0.02375/3))^(3 × 16))
A ≈ $5548
For Sébastien;
P = $3800
r = 2¾% = 0.0275
n = 12
t = 16
Thus;
A = 3800(1 + (0.0275/12))^(12 × 16))
A ≈ 5865
Difference between Sébastien and Melanie's final amount = $5865 - $5548 = $317
