Answer:2.66

Step-by-step explanation:

The z-score for this delivery time is 2.67

A z-score is defined as the fractional representation of data point to the mean using standard deviations.

Given,

Restaurant delivers orders within 30 minutes

The average delivery time for one restaurant is 27 minutes with a standard deviation of three minutes(ц) = 27

One particular order delivery took 35 minutes(X)= 35

ц = 27

σ = 3

X = 35

z-score = (X-ц )/σ

Substitute the values,

z-score =  (35-27 )/3

z-score = 8/3

z-score = 2.67

Hence, the z-score for this delivery time is 2.67.

The path described by the limit of the radar is the circle 50 km circle, and

the path of the ship is the 60 km dashed straight line.

The shortest distance between the ship and Point O, \(\overline {OP}\) is (C) 40 km

Reasons:

The tracking distance of the radar, r = 50 km

Distance the ship moves while within the reach of the radar = 60 km.

Required:

The shortest distance between the ship and the Point O

Solution:

The closest distance between the path of the ship and the Point O is given

by the perpendicular distance from the Point O to the path of the ship

which is given by Pythagoras's theorem and that the perpendicular line

from O to the path of the ship bisects the length of the ship's path.

Let A and B represent the points where the path of the ship intersects with

the circumference of the radar, and let P represent the point the

perpendicular from O intersects AB, we have;

\(\overline {AO}\) = The radius of the radar = 50 km

\(\overline {AB}\) = \(\overline {AP}\) + \(\overline {PB}\)  (segment addition postulate)

\(\overline {AB}\)  = 60 (given)

\(\overline {AP}\) + \(\overline {PB}\) = 60 (transitive property)

\(\overline {AP}\) = \(\overline {PB}\) (definition of \(\overline {AB}\) bisected by \(\overline {OP}\))

∴ \(\overline {AP}\) + \(\overline {PB}\) = \(\overline {AP}\) + \(\overline {AP}\)  = 2× \(\overline {AP}\) = 60

\(\overline {AP}\) = 30

\(\overline {AO}\)² = \(\overline {OP}\)² + \(\overline {AP}\)² (Pythagoras's theorem)

\(\overline {OP}\)² = \(\overline {AO}\)² - \(\overline {AP}\)²

∴  \(\overline {OP}\)² = 50² - 30² = 1600

\(\overline {OP}\) = √(1600) = 40

\(\overline {OP}\) = 40

The shortest distance between the ship and point O is 40 kilometers. (Option C)

The shortest distance between the ship and point O is the distance perpendicular to the line segment AB. We calculate the angle B by the law of cosine:

\(B = \cos^{-1}\left[\frac{50^{2}-60^{2}-50^{2}}{-2\cdot (50)\cdot (60)} \right]\)

\(B \approx 53.130^{\circ}\)

Now we calculate the shortest distance by trigonometric functions:

\(d = OB\cdot \sin B\)

\(d = 50\cdot \sin 53.130^{\circ}\)

\(d = 40\,km\)

The shortest distance between the ship and point O is 40 kilometers. (Option C)

Step-by-step explanation:

The area of the space available for onions is:n12 square feet - 0.12x square feet. number of onion bulbs Mark can plant is: (12 - 0.12x) / y

What is percentage?

Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".

Mark has marked off a certain percentage of the 12 square feet to save for a tomato plant, which means the remaining space will be used for onions.

Let's say Mark marks off x% of the space for the tomato plant. That means he will have (100-x)% of the space for onions.

The area of the space reserved for the tomato plant is:

12 square feet x (x/100) = 0.12x square feet

The area of the space available for onions is:

12 square feet - 0.12x square feet

Let's say each onion bulb needs y square feet of room to grow. Mark can plant as many onion bulbs as can fit in the remaining space, which is:

(12 square feet - 0.12x square feet) / y

So the number of onion bulbs Mark can plant is:

(12 - 0.12x) / y.

Step-by-step explanation:

The coordinates of point P are (5, -3.5). The equation of the circle is \((x - 5)^2 + (y + 3.5)^2 = 1.5^2\). The equation of KL is y = (-4/3)x + 22/3.

To find the coordinates of point P, we can first find the midpoint of MN, which is the center of the circle. The midpoint formula is given by:

Midpoint = ( (x1 + x2) / 2 , (y1 + y2) / 2 )

Using the coordinates of M(3,-5) and N(7,-2), we can calculate the midpoint:

Midpoint = ( (3 + 7) / 2 , (-5 + -2) / 2 ) = (5, -3.5)

Since the midpoint of MN is the center of the circle, the coordinates of P will be the same as the coordinates of the center, which are (5, -3.5).

i. To determine the equation of the circle in the form of \((x-a)^2\) + \((y-b)^2\) = \(r^2\), we can use the center and any point on the circle. We can use point N(7,-2), which lies on the circle.

The radius of the circle is half the length of PN. Therefore, the radius is given by:

Radius =\(1/2 * \sqrt((7 - 5)^2 + (-2 - (-3.5))^2) = 1.5\)

Substituting the values into the equation, we get:

\((x - 5)^2 + (y + 3.5)^2 = 1.5^2\)

ii. To determine the equation of KL in the form of y = mx + c, we can use the slope of the tangent line.

The slope of KL can be calculated as the negative reciprocal of the slope of the radius line MN. The slope of MN is given by:

m = (y2 - y1) / (x2 - x1) = (-2 - (-3.5)) / (7 - 5) = 1.5 / 2 = 0.75

The negative reciprocal of 0.75 is -4/3, which represents the slope of KL.

Using the point N(7,-2) and the slope -4/3, we can use the point-slope form of a line to find the equation of KL:

y - (-2) = (-4/3)(x - 7)

y + 2 = (-4/3)x + 28/3

y = (-4/3)x + 22/3

Answer:

$3606.44

Step-by-step explanation:

The question asks us to calculate the principal amount that needs to be invested in order to earn an interest of $6180 in 28 years at an annual interest rate of 6.12%.

To do this, we need to use the formula for simple interest:

\(\boxed{I = \frac{P \times R \times T}{100}}\),

where:

I = interest earned

P = principal invested

R = annual interest rate

T = time

By substituting the known values into the formula above and then solving for P, we can calculate the amount that James needs to invest:

\(6180 = \frac{P \times 6.12 \times 28}{100}\)

⇒ \(6180 \times 100 = P \times 171.36\)     [Multiplying both sides by 100]

⇒ \(P = \frac{6180 \times 100}{171.36}\)    [Dividing both sides of the equation by 171.36]

⇒ \(P = \bf 3606.44\)

Therefore, James needs to invest $3606.44.

Answer:

3.999 millimeters.

Step-by-step explanation:

To find the height of the cylinder, we can use the formula for the volume of a cylinder:

V = πr²h

Given that the radius (r) of the cylinder is 4 millimeters and the volume (V) is 200.96 cubic millimeters, we can substitute these values into the formula and solve for the height (h).

200.96 = π(4²)h

200.96 = 16πh

To solve for h, we can divide both sides of the equation by 16π:

200.96 / (16π) = h

Using a calculator, we can calculate the approximate value of h:

h ≈ 200.96 / (16 × 3.14159)

h ≈ 3.999

Therefore, the height of the cylinder is approximately 3.999 millimeters.

Answer: Height = 20 inches, Width = 36 inches

Step-by-step explanation:

Let the height be \(h\) and the width be \(h+16\).

Using the formula for the perimeter of a triangle,

\(2(h+h+16)=112\\\\2(2h+16)=112\\\\2h+16=56\\\\2h=40\\\\h=20 \implies h+16=36\)

When 2 items are selected without replacement from a population of 6 items, there are 15 possible samples that can be formed. Option A.

To determine the number of possible samples when 2 items are selected at random without replacement from a population of 6 items, we can use the concept of combinations.

The number of combinations of selecting k items from a set of n items is given by the formula C(n, k) = n! / (k! * (n-k)!), where n! represents the factorial of n.

In this case, we have a population of 6 items and we want to select 2 items. Therefore, the number of possible samples can be calculated as:

C(6, 2) = 6! / (2! * (6-2)!) = 6! / (2! * 4!) = (6 * 5 * 4!) / (2! * 4!) = (6 * 5) / (2 * 1) = 15. Option A is correct.
