The apporoximate length of the RP is 6.1 units, the correct option is B.
What is Pythagoras theorem?The Pythagoras theorem states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of the other two sides of the right-angled triangle.
Given
QR is the tangent to circle P at point Q.
QP = 3 units and QR = 5,.3 units
The length of the RP is given by;
[tex]\rm RP=\sqrt{QP^2+QR^2} \\\\RP=\sqrt{3^2+5.3^2}\\\\ RP=\sqrt{9+28.09} \\\\RP=\sqrt{37.09}\\\\RP= 6.1 \ units[/tex]
Hence, the apporoximate length of the RP is 6.1 units.

The distribution (D) is negatively skewed because more values are concentrated on the right side (tail) of the distribution.
What is Statistic?A statistic is a piece of data derived from a subset of a population. It's the inverse of a parameter — census data, which polls everyone.
Statistics is a method of comprehending data collected about us and the world.
Here, a negatively skewed (also known as left-skewed) distribution is a sort of distribution in which more values are concentrated on the right side (tail) of the distribution graph while the left tail of the distribution graph is longer.
Thus, the distribution (D) is negatively skewed
Hence, the correct answer is an option (D).

You are building a flower bed with a perimeter of 16 feet. The length of the bed is 4 feet longer than the width. What are the dimensions ?
Answer:
Step-by-step explanation:
The perimeter is basically the outline of the shape. The perimeter of a rectangle is given by P=2l+2w, where l is the length and w is the width. Thus, the perimeter of the flower bed would be given by P=2(3n5o)+2(5n5o).

Write down letters of the circled points and order them by least to greasiest. You will spell a word that describes y way to compare quantities
One way to compare quantities is with fractional numbers that represent quantities using divided numbers.
What is a fraction?Fractional number is a mathematical concept that refers to a quantity divided by another quantity. Common fractions are made up of: numerator, denominator and dividing line between them (horizontal or oblique bar).
The denominator "b" expresses the number of equal parts that represent the unit.The numerator "a" indicates how many of them are taken.Some examples of fractional numbers are:

Ruchi measured the area of her kitchen as 2. 81 times 10 Superscript 4 square units. When she recorded the area, she wrote 2. 81 times 10 Superscript 4 square feet. Which statement about her labeling of the units is true? She is correct because dimensions of rooms must always be measured in feet and area would be square feet. She is correct because 2. 81 times 10 Superscript 4 ftSquared is equivalent to 2, 810 ftSquared, which is an average size for a kitchen since area is always so much more than length. She is incorrect because 2. 81 times 10 Superscript 4 is around 30,000 so the units must be smaller than feet. She most likely measured in inches. She is incorrect because 2. 81 is a small number. She probably measured in yards to arrive at such a small value.
Ruchi is incorrect because 2.81×10⁴ is around 30,000. so the units must be smaller than feet.
What is Units conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
As it is given that the measurement that Ruchi wrote is 2.81×10⁴ ft². And, the area of 2.81×10⁴ ft² is 28,100 ft² which is nearly 30,000 ft², while the size of an average house is 2,300 ft². Therefore, the area that is written by Ruchi is too big compared to an average kitchen.
Hence, Ruchi is incorrect because 2.81×10⁴ is around 30,000 so the units must be smaller than feet.

Find the circumference of the object. Use $3.14 or 22/7
for Pi. Round to the nearest hundredth if necessary.
Answer:
18.84
Step-by-step explanation:
Circumference = 2πd
where d = diameter
the shape given has a diameter of 6
to find the circumference we simply plug in the value of the diameter as well as π into the formula
formula : C = πd
π = 3.14 and d = 6
C = 3.14(6) = 18.84cm

27) Jim and his uncle went to the circus. Together they spent $30, 4/15 of that for a bus ride, 2/5 for food, 7/30 for tickets, and the rest on souvenirs. What part of their money did they spend on souvenirs?
Answer:
3 dollars
Step-by-step explanation:
4/15 of 30 = $8
2/5 of 30 = $12
7/30 of 30 = $7
8 + 7 + 12 = $27
30 - 27 = $3
They only had 3 dollars left after spending everything else they had.
Answer:
3/30
Step-by-step explanation:
4/15 so times 15 by 2 and 4 by 2 to get 8/30
leave 7/30 alone
2/5 five times 6 is 30, since you multiplied 5 by 6 you have to do 2 x 6 which is 12, 12/30
now you can add bc a common denominator 12 + 7 + 8 = 27
30 - 27 = 3, so 3/30ths was spent on souvenirs.
Find an equation for the parabola with focus (-4, 0) and directrix x=4.
HELP!
Answer:
[tex]y = - \frac{ {x}^{2} }{16} [/tex]
Step-by-step explanation:
First, notice the diretcrtirx is a negative horinzontal lie so this means we have a parabola facing downwards
Equation of a Parabola with center (h,k) >
[tex](x - h) {}^{2} = - 4p(y - k)[/tex]
Where p is the distance of the vertex to focus/ or distance to vertex to directrix
This emans that the vertex is halfway of (-4,0) and x=4.
Since this is a upwards parabola, the y value that lies on focal axis doesn't change so know this means that
The vertex is halfway between (-4,0) and (4,0).
So the vertex is (0,0).
Plugging that in we get,
[tex] {x}^{2} = - 4py[/tex]
The distance to the vertex or either the focus or directrix is 4 so p=4
[tex] {x}^{2} = - 4(4)y[/tex]
[tex] {x}^{2} = - 16y[/tex]
[tex]y = - \frac{ {x}^{2} }{16} [/tex]

The mean can be found when you add all the numbers in a set, and then divide that sum by the amount of numbers given. Find the average tree growth of four Douglas Fir trees: 2.2 in., 1 1/5 in., and 1 1/2 in.
Answer:
49/30
Step-by-step explanation:
To find the mean, add up 2.2 + 1 1/5 + 1 1/2 to get 49/10
Then divide that by 3 (it says four Douglas trees but you only put 3 types)
49/10 divided by 3 is 49/10 times 1/3, which is 49/30
