Write the final answer in scientific notation.
The correct answer or scientific notation when 3.185× 10¹⁷ is divided by 9.1×10⁸ is 3.46×10⁸ and multiplying 3.185× 10¹⁷ with 9.1×10⁸ is 2.9×10²⁶.
It is given in the question that 3.185× 10¹⁷ is divided by 9.1×10⁸
we can write 3.185×10×10¹⁶ which equals 31.5×10¹⁶.
Now dividing 31.5×10¹⁶ by 9.1×10⁸ we get 3.46×10⁸.
Now multiplying 3.185× 10¹⁷ with 9.1×10⁸ we get 28.98×10²⁵
Converting 28.98×10²⁵ in scientific notation we get 2.9×10²⁶.

Conveyor belt 1 is fasterStep-by-step explanation:
GivenConveyor belt1: m(x) = 157.1xFind the equation of p(x) using table.
We see it is a proportional relationship, therefore:
p(x) = kx125.6 = 2kk = 125.6/2k = 62.8Conveyor belt2: p(x) = 62.8x
As we see 157.1 > 62.8 which means conveyor 1 belt is faster.
Answer:
The conveyor belt 1 is faster.
Step-by-step explanation:
Speed of conveyor belt 1,
→ m(x) = 157.1x
Now the speed of conveyor belt 2,
→ p(x) = x
→ p(125.6) = 2x || p(188.4) = 3x
→ x = 125.6/2 || x = 188.4/3
→ [ p(x) = 62.8 ] || [ p(x) = 62.8 ]
Then the fastest conveyor is,
→ m(x) = 157.1x > p(x) = 62.8
→ 157.1x > 62.8
→ Conveyor 1 > Conveyor 2
Hence, the conveyor belt 1 is faster.
Assume that adults have IQ scores that are normally distributed with a mean of 99.2 and a standard deviation 19.5. Find the first quartile Q,, which is the IQ score separating the bottom 25% from
the top 75%. (Hint: Draw a graph)
The first quartile is
86.135 is the IQ score separating the bottom 25% from the top 75%.
The number between a data set's lowest and median is known as the first quartile. We would utilize a Z table to locate it.
As we are looking on the left side of distribution, value of z-score will be negative.
z-score equation for x : [tex]z = \frac{x-M}{S}[/tex]
[tex]x = zS+M[/tex]
where x = value we're looking for
M = Mean
= 99.2
S = Standard deviation
= 19.5
z = z-score
= -0.67
Putting the value in equation,
x = -0.67*19.5 + 99.2
= -13.065 + 99.2
= 86.135
Hence, 86.135 is the IQ score separating the bottom 25% from the top 75%.

What is the probability that your first strike was not a critical hit?
What is the probability that your first strike was a critical hit but not your second strike?
What is the probability that you are able to cause damage?
What is the probability that your strike was not critical but your next 2 attacks were?
The probabilities in this problem are given as follows:
First strike is a critical hit: 33%.First strike is not a critical hit: 67%.First strike is critical and the second is not: 22%.Cause damage: 11%Not critical followed by two criticals: 7%.What are the probabilities?The probabilities for each strike are given as follows:
Critical hit: 33%.Not a critical hit: 67%, as 100 - 33 = 67.The probabilities are independent, meaning that for each trial they are the same.
Thus the probability that your first strike was a critical hit but not your second strike is obtained as follows:
P = 0.33 x 0.67 = 0.2211 = 22%. (rounded).
Damage is caused with two consecutive critical hits, hence:
p = 0.33 x 0.33 = 0.11 = 11%.
The final probability, that your strike was not critical but your next 2 attacks were, is obtained as follows:
p = 0.67 x 0.33 x 0.33 = 0.07 = 7%.

A line with a slope of -7/16 passes through the point (-16, 7). What is its equation in
slope-intercept form?
A equation of line with a slope of -7/16 passes through the point (-16, 7) is y = (-7/16)x
We know that the formula for the slope-point form of equation of line:
(y - y1) = m(x - x1)
Let (x1, y1) = (-16, 7)
and slope m = -7/16
Using above formula,
(y - 7) = (-7/16)(x - (-16))
y - 7 = (-7/16)(x + 16)
y = -7/16x - 7 + 7
y = (-7/16)x
This equation is slope-intercept form (y = mx + c) with slope -7/16 and y-intercept 0.
Therefore, a equation of line with a slope of -7/16 passes through the point (-16, 7) is y = (-7/16)x

Answer:
t=1.33333 seconds
Step-by-step explanation:
1. We are give the the position function, s(t). We must differentiate s(t) twice in order to find the acceleration function, a(t).
s(t) = t⁶-2t⁵
Taking the power rule to differentiate s(t), we find the velocity function, v(t).
v(t) = d/dt (t⁶-2t⁵)
v(t) = 6t⁵-10t⁴
Differentiate v(t) using the power rule again to find the acceleration function, a(t).
a(t) = d/dt (6t⁵-10t⁴)
a(t) = 30t⁴-40t³
2. To find the other t value where acceleration is equal to zero, we must set a(t) to zero.
a(t) = 30t⁴-40t³ = 0
3. Algebraically solve for t. Factoring out 10t³ from a(t), we have:
10t³(3t-4)=0
Our solutions are t=0 and t=4/3.
The other value of t when acceleration is equal to zero is 4/3, or 1.33333 seconds.

How to compare the mean of the number of plants?From the question, we have the table of values that can be used in our computation:
In the table, we have the following rows
Plants and Number of tomatoes
The mean of the number of plants is calculated as
Mean plant = Total number of tomatoes/Total number of plants
For the four plants, we have
Total number of tomatoes = 31 + 25 + 6 + 28 = 90
Total number of plants = 4
Substitute the known values in the above equation So, we have the following equation
Mean plant = 90/4
Mean plant = 22.5
For the three plants, we have
Total number of tomatoes = 31 + 25 + 28 = 84
Total number of plants = 3
Substitute the known values in the above equation So, we have the following equation
Mean plant = 84/3

Write the range and domain using Interval notation.
Answer:
Domain: (-∞, +∞)

Step-by-step explanation:
Domain is the "allowable x-values/inputs"
Range is the "possible y-values/outputs when the x-values in the domain are inputted".
From the graph, notice how each end of it extends infinitely to the left and to the right. This means that the domain is infinite and there are no restrictions. Writing it in interval location would look like this:
(-∞, +∞)
Also, notice how the y-values increase from the vertex but do not go below it. That suggests that the range is "lower-bounded" to the vertex, and increases infinitely. Writing it in interval location would look like this:

The slope is -5/3
From the question, we have
slope, m = change in y/change in x
= (-6+1)/(8-5)
=-5/3
The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.
Slope of a Line :
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
As a result, m = change in y/change in x = y/x is the formula for the change in y-coordinate with respect to the change in x-coordinate.
where "m" represents a line's slope.
The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.
