what are the angle measures?
there are $54$ chips in a box. each chip is either small or large. if the number of small chips is greater than the number of large chips by a prime number of chips, what is the greatest possible number of large chips?
The greatest possible number of large chips would be 0, assuming there are no small chips.
To find the greatest possible number of large chips, we need to maximize the difference between the number of small and large chips. Since the difference must be a prime number, we should start by finding the largest prime number less than 54.
The largest prime number less than 54 is 53. Let's assume that there are 53 more small chips than large chips.
If the number of small chips is 53 more than the number of large chips, we can set up the following equation:
Number of small chips = Number of large chips + 53
Since there are 54 chips in total, we can substitute the value into the equation:
54 = Number of large chips + Number of large chips + 53
Simplifying the equation, we get:
54 = 2 * Number of large chips + 53
Subtracting 53 from both sides, we have:
1 = 2 * Number of large chips
Dividing both sides by 2, we find:
Number of large chips = 1/2
However, the number of large chips cannot be a fraction. Therefore, it is not possible to have 53 more small chips than large chips in this scenario.
As a result, the greatest possible number of large chips would be 0, assuming there are no small chips.

✓lies on CD
The x-intercept of CD is 17.
Since CD is perpendicular to AB and passes through point C(5, 12), we can find the equation of CD using the slope-intercept form.
The slope of CD can be determined using the negative reciprocal of the slope of AB.
Slope of AB = (change in y) / (change in x) = (14 - (-3)) / (7 - (-10)) = 17 / 17 = 1
The negative reciprocal of 1 is -1. Therefore, the slope of CD is -1.
Using the slope-intercept form, we can write the equation of CD as:
y - y1 = m(x - x1),
where (x1, y1) is a point on CD. Let's use point C(5, 12):
y - 12 = -1(x - 5)
Simplifying the equation, we have:
y - 12 = -x + 5
y = -x + 17
To find the x-intercept, we set y = 0 and solve for x:
0 = -x + 17
x = 17
Therefore, the x-intercept of CD is 17.

For State budget planning, Louisiana Secretary of Health claimed that the Mean cost of a (non-ICU) COVID hospital treatment per patient is less than $25,000. To confirm Governor Edwards took a simple random sample of 25 (non-ICU) COVID patient costs. It showed a Sample Mean =$26,000 and Sample Standard deviation =$2000. Test the Secretary' claim using 5% level of significance. State your conclusion. It is important to the Governor for Budgetary Planning.
The test results do not provide sufficient evidence to reject the Secretary's claim that the mean cost of a (non-ICU) COVID hospital treatment per patient is less than $25,000 at a 5% level of significance.
To test the Secretary's claim, the Governor used a one-sample t-test. The null hypothesis (H0) states that the mean cost of a (non-ICU) COVID hospital treatment per patient is $25,000 or more, while the alternative hypothesis (Ha) states that the mean cost is less than $25,000.
The test statistic is calculated as (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size)). In this case, the test statistic is (26,000 - 25,000) / (2,000 / sqrt(25)) = 2.5.
Next, the critical value is determined based on the level of significance and the degrees of freedom (n - 1). Since the sample size is 25, the degrees of freedom is 24. The critical value for a one-sided t-test at a 5% level of significance is -1.711.
Since the test statistic (2.5) is greater than the critical value (-1.711), we fail to reject the null hypothesis. This means that there is not enough evidence to support the Secretary's claim that the mean cost of a (non-ICU) COVID hospital treatment per patient is less than $25,000. Therefore, based on the sample data, the Governor cannot conclude that the mean cost is less than $25,000 for budgetary planning purposes.

The triangle on the right is a scaled copy of the triangle on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.
First triangle
15
15
second triangle
45/2
45/2
Answer: 3
Step-by-step explanation:
The scale factor is the ratio of corresponding side lengths of the two triangles.
In the given triangles, the length of the corresponding sides of the triangles are:
For the first triangle:
Side A = 15 units
Side B = 15 units
For the second triangle:
Side A = 45/2 units
Side B = 45/2 units
To find the scale factor, we can divide the length of one side of the second triangle by the corresponding length of the first triangle.
For example, we can use Side A:
Scale factor = (length of Side A of the second triangle) / (length of Side A of the first triangle)
Scale factor = (45/2) / 15
Scale factor = (45/2) * (1/15)
Scale factor = 3/2
Since the two triangles are scaled copies of each other, the scale factor should be the same for all corresponding sides.
Thus, the scale factor is 3 (in simplest form).

A horizontal curve is to be designed with a 2000 feet radius. The curve has a tangent length of 400 feet and its pi is located at station 103+00. Determine the stationing of the PT.
A horizontal curve is a curve that is used to provide a transition between two tangent sections of a roadway. To connect two tangent road sections, horizontal curves are used. Horizontal curves are defined by a radius and a degree of curvature. The curve's radius is given as 2000 feet. The tangent length is 400 feet.
The pi is located at station 103+00.
To determine the stationing of the PT, we must first understand what the "pi" means. PC or point of curvature, PT or point of tangency, and PI or point of intersection are the three primary geometric features of a horizontal curve. The point of intersection (PI) is the point at which the back tangent and forward tangent of the curve meet. It is an important point since it signifies the location of the true beginning and end of the curve. To calculate the PT station, we must first determine the length of the curve's arc. The formula for determining the length of the arc is as follows:
L = 2πR (D/360)Where:
L = length of the arc in feet.
R = the radius of the curve in feet.
D = the degree of curvature in degrees.
PI (103+00) indicates that the beginning of the curve is located 103 chains (a chain is equal to 100 feet) away from the road's reference point. This indicates that the beginning of the curve is located 10300 feet from the road's reference point. Now we need to calculate the degree of curvature
:Degree of curvature = 5729.58 / R= 5729.58 / 2000= 2.8648 degrees. Therefore, the arc length is:
L = 2πR (D/360)= 2π2000 (2.8648/360)= 301.6 feet.
The length of the curve's chord is equal to the length of the tangent, which is 400 feet. As a result, the length of the curve's long chord is: Long chord length = 2R sin (D/2)= 2 * 2000 * sin(2.8648/2)= 152.2 feet To determine the stationing of the PT, we can use the following formula: PT stationing = PI stationing + Length of curve's long chord= 10300 + 152.2= 10452.2Therefore, the stationing of the PT is 10452+2.

the lendght of an arc intercepted by a cental angle in 6 pi the radios of the circle is 34 . find the measure of the central angle
The measure of the central angle is 3π/17 radians.
L = rθ
where L is the length of the arc, r is the radius of the circle, and θ is the measure of the central angle in radians.
The radius of the circle is 34 and the length of the arc intercepted by the central angle is 6π. Substituting these values into the formula, we get:
6π = 34θ
To solve for θ, we can divide both sides by 34:
6π/34 = θ
Simplifying the right side, we get:
3π/17 = θ
The measure of the central angle is 3π/17 radians.
The measure of the central angle, we can use the formula for the length of an arc:
Arc length = Radius × Central angle (in radians)
We are given the arc length (6π) and the radius (34). We can rearrange the formula to solve for the central angle:
Central angle = Arc length / Radius
Central angle = (6π) / 34
Now, divide 6π by 34 to get the measure of the central angle:
Central angle ≈ 0.556π radians

The scalar equation of the plane that contains given points and lines can be written as: (-4)(x-1) + 4(y-2) + (-10)(z-3) = 0.
What is equation of plane?
A given point p(x, y, z) that is located on the plane and a normal vector n define the equation of a plane. A plane's vector and scalar components can be used to formulate the equation for the plane.
The parametric form of line equation,
\(p = p_0 + t. \vec v\)
On comparing with the given equation in question, we can say that,
p = {x, y, z}, p₀ = {0, 6, 1,}, vec(v) = {3, -2, -2}
The scalar equation can be given by,
\([ \vec \omega, p - p_1] = 0\)
Here, p₁ = {1, 2, 3} and ω is perpendicular to v and to the segment p₁ - p₀ So,
\(\vec \omega = \vec v \times (p_1 - p_0) = ( 3, -2, -2 ) \times (1, -4, -2)\)
then,
\(\vec \omega = (-4, 4, -10)\)
Therefore, the scalar equation can be written as:
(-4)(x-1) + 4(y-2) + (-10)(z-3) = 0
It can also be written as:

By assuming that Toshiro spent less than an hour on both activities and analyzing the time constraints, we reach a contradiction. Thus, we can conclude that Toshiro must have spent more than an hour on at least one of the activities, during his two-hour gym session.
To prove that Toshiro did one of the activities, swimming laps or lifting weights, for more than an hour during his two-hour gym session, we can use proof by contradiction. Suppose Toshiro spent less than an hour on both activities combined. By analyzing the time constraints, we can demonstrate that this assumption leads to a contradiction. Therefore, it can be concluded that Toshiro must have spent more than an hour on at least one of the activities.
Let's assume that Toshiro spent less than an hour on both swimming laps and lifting weights. Since Toshiro was at the gym for just over two hours, it implies that he must have spent the remaining time on activities other than swimming and weightlifting.
If Toshiro spent less than an hour on swimming laps, that would leave him with over an hour for other activities. Similarly, if he spent less than an hour on lifting weights, he would still have over an hour left for other activities.

i need help on this (-4)²

Answer:
Step-by-step explanation:
To have anything to a power is just multiplying the number as many times as it says to. ex. 2^3 is two times itself 3 times. 2 x 2 x 2= 8
In your case, you need to multiply -4 x -4 because the exponents tell you how many of the number you multiply.
-4 x -4 = 16
Hope this helps :)
