Answer: 0.03538944
Step-by-step explanation:
Given, The accuracy of missile = 96%
i.e. The probability that it will hit the shot = 0.96
Probability of missing the shot = 1-0.96= 0.04
Now, each missile is independent of other.
Therefore, the probability only the second one misses = (probability that first will hit the shot) x (probability that second one misses ) x (probability that third will hit the shot)x (probability that fourth will hit the shot)
Thus, the probability only the second one misses is [tex](0.96)(0.04)(0.96)(0.96)=0.03538944[/tex]
Hence, the required probability = 0.03538944

Use the fundamental theorem of algebra to determine the number of roots for each polynomial function
shown.
f(x) = (x2+6)2
Answer:
4 roots.
Step-by-step explanation:
The number of roots is equal to the degree of the function
For example
f(x) = x^2 has 2 roots because the highest exponent is 2.
f(x) = x^3 + 2x - 1 has 3 roots , because the function is of degree 3.
(x^2+ 6)^2 = x^4 + 12x^2 + 36 so because of the x^4 it is of degree 4 and has 4 roots.

294 gumballs were added because if u subtract 230 from 1696 you get 1466 which was the number you had when you are 230 gumballs so you take 1466 and subtract it from 1760 you get the amount of gumballs that was added.

Solve the matrix equation for a, b, c, and d. [1 2] [a b] [6 5][3 4] [c d]= [19 8]
Answer:
The answer is "[tex]\bold{\left[\begin{array}{cc}a&b\\c&d\end{array}\right] = \left[\begin{array}{cc}7&-2\\ -\frac{1}{2}&\frac{7}{2}\end{array}\right]}[/tex]".
Step-by-step explanation:
[tex]\bold{\left[\begin{array}{cc}1&2\\3&4\end{array}\right] \left[\begin{array}{cc}a&b\\c&d\end{array}\right] = \left[\begin{array}{cc}6&5\\ 19&8\end{array}\right]}[/tex]

After calculating the L.H.S part compare the value with R.H.S:
[tex]\left[\begin{array}{cc}a+2c&b+2d\\3a+4c&3b+4d\end{array}\right]= \left[\begin{array}{cc}6&5\\ 19&8\end{array}\right]} \\\\[/tex]
[tex]\to a+2c =6....(i)\\\\\to b+2d =5....(ii)\\\\\to 3a+4c =19....(iii)\\\\\to 3b+4d = 8 ....(iv)\\\\[/tex]
In equation (i) multiply by 3 and subtract by equation (iii):
[tex]\to 3a+6c=18\\\to 3a+4c=19\\\\\text{subtract}... \\\\\to 2c = -1\\\\\to c= - \frac{1}{2}[/tex]
put the value of c in equation (i):

[tex]\to 3b+4 (\frac{7}{2})=8\\\\\to 3b+4 \times \frac{7}{2}=8\\\\\to 3b+14=8\\\\\to 3b =8-14\\\\\to 3b = -6\\\\\to b= \frac{-6}{3}\\\\\to b= -2[/tex]
The final answer is "[tex]\bold{\left[\begin{array}{cc}a&b\\c&d\end{array}\right] = \left[\begin{array}{cc}7&-2\\ -\frac{1}{2}&\frac{7}{2}\end{array}\right]}[/tex]".
For a regular 15-sided polygon, what is the degree of rotation?
Answer:
360/15 = 24
Step-by-step explanation:
If an exterior angle of a regular polygon is 21.2º, how many sides does the polygon have?
Answer:
option 4. 17
Step-by-step explanation:
sum of angles = exterior angle x n
360° = 21.2° n
n = 360 / 21.2
n = 17
Number of sides of the regular polygon with exterior angle 21.2° is equals to 17 sides.
What is polygon?" Polygon is defined as the two dimensional geometric shape which has n number of finite sides."
Formula used
360° = (Exterior angle of polygon ) × ( number of sides of polygon)
According to the question,
Given,
Exterior angle of a regular polygon = 21.2º
'n' represents the number of sides
Substitute the value in the formula to get number of sides,
[tex]360\°= (21.2\°) (n)[/tex]
⇒ [tex]n = \frac{360\°}{21.2\°}[/tex]
⇒ [tex]n= 16.98[/tex]
⇒ n≈ 17 sides
Hence, number of sides of the regular polygon with exterior angle 21.2° is equals to 17 sides.

NEED ANSWER NOW!!! Steven has one bag that contains three table tennis balls numbered 1, 2, and 3. He also has a second bag that contains four table tennis balls lettered A, B, C, and D. Suppose Steven combined the table tennis balls into one large bag instead of two individual bags. What would be the P(1, B) without replacement?
Answer:
P(1, B) = 1/12
Step-by-step explanation:
if given one group of 3 objects, in this case tennis balls labeled 1, 2, and 3. And another group of 4 objects, labeled a, b, c, and d. the combined probability would be 1/3 * 1/4 = 1/12. This is because there is a 1/3 chance of picking one particular object from a set of 3 total objects, and a 1/4 chance of picking one particular object from a set of 4 total objects.
The probability of drawing 1 numbered ball in the first attempt and then drawing B numbered ball in the second attempt is 1/42.
What is conditional probability ?Conditional probability is when occurrence of an event depends upon the occurrence of another event.In case of without replacement one event is dependent on another.
According to the given question
Steven has one bag that contains three table tennis balls numbered 1, 2, and 3. He also has a second bag that contains four table tennis balls lettered A, B, C, and D and Steven combined the table tennis balls into one large bag instead of two individual bags.
Here we don't need to find the probabilities individual bags.
So after he combined them into one large bag there are 7 balls in that large bag namely 1, 2, 3, A, B, C, D
P(1) = 1/7
with without replacement there is now 6 balls in the large bag
∴ p(B) = 1/6
So the probability of drawing 1 numbered ball in the first attempt and then B numbered ball in the second attempt is p(1)p(B)
∴P(1,B) is
= (1/7)×(1/6)
= 1/42.

solve for x 5x-2=3x+4
Answer:
3
Step-by-step explanation:
Simplifying
5x + -2 = 3x + 4
Reorder the terms:
-2 + 5x = 3x + 4
Reorder the terms:
-2 + 5x = 4 + 3x
Solving
-2 + 5x = 4 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-2 + 5x + -3x = 4 + 3x + -3x
Combine like terms: 5x + -3x = 2x
-2 + 2x = 4 + 3x + -3x
Combine like terms: 3x + -3x = 0
-2 + 2x = 4 + 0
-2 + 2x = 4
Add '2' to each side of the equation.
-2 + 2 + 2x = 4 + 2
Combine like terms: -2 + 2 = 0
0 + 2x = 4 + 2
2x = 4 + 2
Combine like terms: 4 + 2 = 6
2x = 6
Divide each side by '2'.

А. 4 √x^3
B. 1/ x^-1
C. 10 √x^5 times x^4 times x^2
D. X1/3 times x^1/3 times x^1/3
Answer:
B and D
Step-by-step explanation:
B:
Anything to a negative power means that it is 1/that to the positive power.
E.g. x^-1 = 1/x^1
In other words, anything to the power of a negative switches sides of a fraction (i.e. if in numerator moves to denominator and vice versa.)
1/x^-1 = 1/1/x^1 which is just equal to x, because there are x number of 1/xs in one (1/x * x =1) Therefore Option B is equal to just x.
D: (assuming the first given term is x^1/3 and not X1/3 (?) Correct me if I'm wrong).
x^1/3 * x^1/3 * x^1/3 is also equal to just x.
This is because when multiplying together terms with the same base (x in this case) the exponents just add together, so:
x^1/3 * x^1/3 * x^1/3 = x^(1/3 +1/3 +1/3) = x^1 = x.
Therefore B and D are equivalent because they both equal x.

If m rst= 12x-1, m rsu = 9x-15 and m ust = 53 find each measure
Answer:
x = 13
m<RST = 155°
m<RSU = 102°
Step-by-step explanation:
m<RST = (12x - 1)°
m<RSU = (9x - 15)°
m<UST = 53°
m<UST + m<RSU = m<RST (angle addition postulate)
53 + (9x - 15) = (12x - 1) (substitution)
Solve for x
53 + 9x - 15 = 12x - 1
53 - 15 + 9x = 12x - 1
38 + 9x = 12x - 1
Subtract 12x from each side
38 + 9x - 12x = 12x - 1 - 12x
38 - 3x = - 1
Subtract 38 from each side
38 - 3x - 38 = -1 - 38
-3x = -39
Divide both sides by -3
x = 13
m<RST = (12x - 1)°
Plug in the value of x
m<RST = 12(13) - 1 = 156 - 1 = 155°
m<RSU = (9x - 15)°
m<RSU = 9(13)x - 15 = 117 - 15 = 102°
The measures of each angle are:
m<RSU = 102°
m<RST = 155°
m<UST = 53°
The given parameters are:
m<RST = (12x - 1)°
m<RSU = (9x - 15)°
m<UST = 53°
Note that:
m<RST = m<RSU + m<UST
Substitute m<RST = 12x - 1, m<RSU = 9x - 15, and m<UST = 53 into the equation above in order to solve for x
m<RST = m<RSU + m<UST
12x - 1 = 9x - 15 + 53
12x - 9x = -15 + 53 + 1
3x = 39
x = 39/3
x = 13
To find the measure of <RST, substitute x = 3 into m<RST = 12x - 1
m<RST = 12(13) - 1
m<RST = 155°
To find the measure of <RSU, substitute x = 3 into m<RSU = 9x - 15
m<RSU = 9(13) - 15
m<RSU = 102°

Click the icon to view a table of English and Metric Equivalents.
Answer: Kukui (Hawaii) has the greater average rainfall than Melchior (Antarctic Peninsula) by 8,099.2 millimetres.
Step-by-step explanation:
Given: The average rainfall amounts for two of the world's wettest places:
Kukui (Hawaii): 9,293 millimetres
Melchior (Antarctic Peninsula): 47 inches
Since 1 inch = 25.4 millimetres
∴ 47 inches = 47 × 25.4 millimetres
= 1193.8 millimetres
i.e. Melchior (Antarctic Peninsula) has 1193.8 millimetres of average rainfall.
Clearly, 9,293 millimetres> 1193.8 millimetres
So, Kukui (Hawaii) has the greater average rainfall .
Difference = 9293 - 1193.8 = 8099.2 millimetres
So Kukui (Hawaii) has the greater average rainfall than Melchior (Antarctic Peninsula) by 8,099.2 millimetres.
