The expression 3p⁵ ₓ 8p³ / 2p can be simplified to 12p⁷.
Step-by-step explanation:
To simplify:
3p⁵ ₓ 8p³ / 2p
= (3 ₓ 8)(p⁵ ₓ p³) / 2p
= 24p⁸ / 2p
= 12p⁷

There are 320 students in a school, There are 36 more boys than girls. What fraction of the students are boys?
Answer:
89/160
Step-by-step explanation:
Total number of students= 320
Total number of students=x+y=320
Let x= number of boys
Let y= number of girls
If there are 36 more boys than girls:
36+y=x
x+y=320 ( given x= 36+y)
36+y+y=320
36+2y=320
2y=320-36
2y=284
y=284/2
y=142
Therefore number of girls=142
Since 36+y=x
36+142=x
x=178
Therefore number of boys =178
Fraction of students that are boys=
178/320
89/160

Answer:
x = 30°
Step-by-step explanation:
Since 2 of the sides are congruent then the triangle is isosceles and the 2 base angles are congruent, both 75°
The sum of the 3 angles in a triangle = 180°, then
x = 180° - (75 + 75)° = 180° - 150° = 30°

The shelf life of a battery produced by a major company is known to be normally distributed, with a mean life of 4 years and a standard deviation of 0.75 years. What is the upper quartile of the battery shelf life? What range of years contains the middle 68% of all battery shelf lives?
Answer:
4.5 years ; (3.25, 4.75)
Step-by-step explanation:
Given that :
Mean , m = 4
Standard deviation, s = 0.75
The upper quartile, which is the 3rd quartile of a standard normal distribution is 0.67
Therefore, the upper quartile Q3:
Q3 = mean + 0.67 * standard deviation
Q3 = 4 + 0.67(0.75)
Q3 = 4 + 0.5025
Q3 = 4.5025
Q3 = 4.5 years
Range of values that contain the middle 68%
According to the empirical rule;
68% is within 1 standard deviation of the mean
Therefore ;
Interval will be ;
Mean ± 1 standard deviation
(4 - 0.75) ; (4 + 0.75)
(3.25, 4.75)

In 5 + In x = 1
this is from my algebra 2 class and we just have to solve
Answer:
2
Step-by-step explanation:
In 5 + In x = 1
In 5 + In x = In 10 (Because In 10 = 1)
In(5x) = In 10
5x = 10
x = 10/5
x = 2
Solve for x check the picture
Answer:
x = 21
Step-by-step explanation:
2x and 42 are alternate angles and are congruent, so
2x = 42 ( divide both sides by 2 )
x = 21
Find the slope of the line that contains the pair of points: (6,3)
Answer:
1/2
Step-by-step explanation:
Let the coordinate points be (6,3) and (4,2)
Slope = y2-y1/x2-x1
x1 = 6, y1 = 3, x2 = 4 and y2 =2
Substitute
slope = 2-3/4-6
Slope = -1/-2
Slope = 1/2
Hence the slope of the coordinate is 1/2
Note that the other Coordinate was assumed

If you roll a number cube two times, what is the probability of rolling an even on the first roll and a four on the second roll?
Answer:
1/12
Step-by-step explanation:
Probability is a ratio derived as the number of possible outcomes divided by the total outcome.
On a number cube, the even sides are 2, 4 and 6. This means that the possible outcome for rolling an even is 3 while the total outcome is 6. Hence the probability of rolling an even P(E)
= 3/6
The probability of rolling a 4 P(4)
= 1/6 (4 appears on one side)
Hence the probability of rolling an even on the first roll and a four on the second roll
P(En4) = 3/6 * 1/6
= 3/36
= 1/12

Step-by-step explanation:
1. An AP has a common difference of 3. Given that the nth term is 32, and the sum of the first n terms is 185, calculate the value of n.
Answer:
The value of n is 10
Step-by-step explanation:
The formula of the nth term of the arithmetic progression is a[tex]_{n}[/tex] = a + (n - 1)d
a is the first termd is the common difference between each 2 consecutive termsn is the position of the termThe formula of the sum of nth terms is S[tex]_{n}[/tex] = [tex]\frac{n}{2}[/tex] [2a + (n - 1)d]
∵ An AP has a common difference of 3
∴ d = 3
∵ The nth term is 32
∴ a[tex]_{n}[/tex] = 32
→ Substitute them in the 1st rule above
∵ 32 = a + (n - 1)3
∴ 32 = a + 3(n) - 3(1)
∴ 32 = a + 3n - 3
→ Add 3 to both sides
∴ 35 = a + 3n
→ Switch the two sides
∴ a + 3n = 35
→ Subtract 3n from both sides
∴ a = 35 - 3n ⇒ (1)
∵ The sum of the first n terms is 185
∴ S[tex]_{n}[/tex] = 185
→ Substitute the value of S[tex]_{n}[/tex] and d in the 2nd rule above
∵ 185 = [tex]\frac{n}{2}[/tex] [ 2a + (n - 1)3]
∴ 185 = [tex]\frac{n}{2}[/tex] [2a + 3(n) - 3(1)]
∴ 185 = [tex]\frac{n}{2}[/tex] [2a + 3n - 3]
→ Multiply both sides by 2
∴ 370 = n(2a + 3n - 3)
∴ 370 = 2an + 3n² - 3n
→ Substitute a by equation (1)
∴ 370 = 2n(35 - 3n) + 3n² - 3n
∴ 370 = 70n - 6n²+ 3n² - 3n
→ Add the like terms in the right side
∵ 370 = -3n² + 67n
→ Add 3n² to both sides
∴ 3n² + 370 = 67n
→ Subtract 67 from both sides
∴ 3n² - 67n + 370 = 0
→ Use your calculator to find n
∴ n = 10 and n = 37/3
∵ n must be a positive integer ⇒ 37/3 neglecting
∴ n = 10
∴ The value of n is 10
What is the function of this graph?
Answer:
x=y^2-2
Step-by-step explanation:
This graph, is a parabola that opens to the right.
To answer this question, we just use the vertex form of a sideways parabola- x=a(y-k)^2+h.
In this case, the vertex is (-2, 0), and our value of a is 1, since it opens to the right.
This gives us: x=1(y-0)^2+(-2)
Which simplifies to: x=y^2-2.
Also, the answer to the previous two questions are wrong.
