How do you regroup ones?.
Answers
When one column adds up to more than 10, you regroup 10 Ones into 1 Tens
Regrouping is done by making groups of tens during operations like subtraction and addition. Regrouping means rearranging numbers into groups by place value to make it easier to carry out operations. This process is called regrouping because you're rearranging numbers into place value to carry out the process.
To regroup means to rearrange groups in place value to carry out an operation.
When one column adds up to more than 10, you regroup 10 Ones into 1 Tens. Don't put the carry over in the answer area at the bottom of the column. Write it at the top. After we carry the 1, we add all the Tens place digits, including the carry.
Therefore, when one column adds up to more than 10, you regroup 10 Ones into 1 Tens

(1 point) A baseball is thrown from the stands 10 ft above the field at an angle of 80° up from the horizontal. When and how far away will the ball strike the ground if its initial speed is 30 ft/sec
Answers
The ball will strike the ground in `1.838 sec` and `11.812 ft` away from the point of projection.
The given values are: Initial Speed = 30 ft/sec Height (h) = 10 ft Angle (θ) = 80°
Using the formula: `Horizontal distance (d) = (Initial Speed (v) * time (t) * cosθ)` Vertical distance (h) = `Initial Speed (v) * sinθ * t - 0.5 * g * t^2`. Where `g` is the acceleration due to gravity `g = 32 ft/sec^2`. Now, since the baseball hits the ground, therefore h = 0.
Putting the values we get: 0 = (30 * sin80° * t) - (0.5 * 32 * t^2)0 = (30 * 0.9848 * t) - (16 * t^2)
t = 0 or 1.838 sec
So, the time taken by the ball to hit the ground is `1.838 sec`. Using the formula, `Horizontal distance (d) = (Initial Speed (v) * time (t) * cosθ)`d = (30 * 1.838 * cos80°) d = 11.812 ft. So, the ball will strike the ground in `1.838 sec` and `11.812 ft` away from the point of projection.

With Alpha set to .05, would we reduce the probability of a Type
I Error by increasing our sample size? Why or why not? How does
increasing sample size affect the probability of Type II Error?
Answers
With Alpha set to .05, increasing the sample size would not directly reduce the probability of a Type I error. The probability of a Type I error is determined by the significance level (Alpha) and remains constant regardless of the sample size.
However, increasing the sample size can indirectly affect the probability of a Type I error by increasing the statistical power of the test. With a larger sample size, it becomes easier to detect a statistically significant difference between groups, reducing the likelihood of falsely rejecting the null hypothesis (Type I error).
Increasing the sample size generally decreases the probability of a Type II error, which is failing to reject a false null hypothesis. With a larger sample size, the test becomes more sensitive and has a higher likelihood of detecting a true effect if one exists, reducing the likelihood of a Type II error. However, it's important to note that other factors such as the effect size, variability, and statistical power also play a role in determining the probability of a Type II error.

if the patient must receive 0.190 millicuries of na-24 per kilogram of body weight, how many millicuries should be given to a patient who weighs 55.2 kilograms?
Answers
If the patient must receive 0.190 millicuries of Na-24 per kilogram of body weight, 10.4928 millicuries of Na-24 should be given to a patient who weighs 55.2 kilograms.
To calculate the number of millicuries that should be given to a patient, you have to multiply the dose per kilogram of body weight by the patient's body weight in kilograms.
Here is the formula:
Millicuries to be given = dose per kilogram of body weight × body weight in kilograms
So, if the patient must receive 0.190 millicuries of Na-24 per kilogram of body weight, 10.4928 millicuries should be given to a patient who weighs 55.2 kilograms.
That is,0.190 millicuries /kg × 55.2 kg = 10.4928 millicuries
Therefore, 10.4928 millicuries of Na-24 should be given to a patient who weighs 55.2 kilograms.

Step-by-step explanation:
No change in amount of dollars, domain stays the same, slope of the line is then 0
The slope of the line will be 0.
The admission fee is $54.99, which is not change as time spend at the park increases.
What is Slope of line?
The slope of a line is a number that describe the both direction and the steepness of the line.
Given that;
The table shows the amount x (in hours) of time you spend at a theme park and the admission fee y (in dollars) to the park.
And, The points represented by the table lie on a line.
Now, The slope of the line with two points (x₁ , y₁) and (x₂, y₂) will be;
m = (y₂ - y₁) / (x₂ - x₁)
So, The slope of the line with two points (6, 54.99) and (7, 54.99) is;
m = (y₂ - y₁) / (x₂ - x₁)
m = (54.99 - 54.99) / 7 - 6
m = 0/1
m = 0
Thus, Slope of the line will be 0.

find all points of intersection of the given curves. (assume 0 ≤ theta ≤ ????. order your answers from smallest to largest theta. if an intersection occurs at the pole, enter pole in the first answer blank.) r
Answers
The points of intersection are:
(0, 0)
(0, π)
(√(3)/2, π/3)
(-√(3)/2, 5π/3)
To find the points of intersection between the curves r = sin(θ) and r = sin(2θ), we can equate the two equations and solve for theta.
Setting sin(θ) = sin(2θ), we have:
sin(θ) = sin(2θ)
Using the identity sin(2θ) = 2sin(θ)cos(θ), we can rewrite the equation as:
sin(θ) = 2sin(θ)cos(θ)
Now, we have two possibilities:
sin(θ) = 0:
This occurs when θ = 0 or θ = π. At these points, the value of r is also 0 since r = sin(θ). Therefore, the points of intersection are (0, 0) and (0, pi).
sin(θ) ≠ 0:
Dividing both sides of the equation by sin(θ), we get:
1 = 2cos(θ)
Solving for cos(θ), we have:
cos(θ) = 1/2
This occurs when theta = π/3 or theta = 5π/3. At these points, the value of r is sin(θ), so the points of intersection are (sin(π/3), π/3) and (sin(5π/3), 5π/3).
Therefore, the points of intersection are:
(0, 0)
(0, π)

The proof of every positive integer k that divides the order of g, there exists a subgroup h of g of order k is shown below:
What is Subgroup?A subgroup is a group nested inside another group. The subgroup test is used on subsets of a group to determine if they are subgroups. A proper subgroup is a subgroup that does not contain all of the original group, while a trivial subgroup contains only the identity.
Suppose k ∣ g ⟹n=dk:
If h(g)=⟨g⟩ is cyclic then
clearly K:=|⟨g^d⟩|=k .
Suppose now we have
1≠H≤h(g),
|H|=k and
let r>0 be the minimal natural number s.t.
g^r ∈ H , then
1=(g ^ r)^k = g^(r k)
⟹n ∣ r k ⟹ r k=ns =d ks ⟹ r= ds ⟹ s ∣ d
and from here we have
g^ r=(g^ d)^ s ∈K
Also, |H|=||K|
we get equality and thus uniqueness of K.

Answers
The the function to estimate the average age of employee of a company is A(s)=0.285s + 59 , then the average age of employee in 2003 is 65.27 and in 2009 is 66.98
To estimate the average age of an employee in 2003, we need to find the value of A(s) when s = 22 ;
because the number of years between 2003 and 1981 is = 22 years ;
So , A(22) = 0.285×22 + 59 = 65.27 ;
The average age of an employee in 2003 is approximately 65.27.
To estimate the average age of an employee in 2009,
we need to find the value of A(s) when s = 28
because the number of years between 2009 and 1981 is = 28 years ;
So , A(28) = 0.285×28 + 59 = 66.98 ;
The Average age of employee in 2009 is approximately 71.48.
