Answer:

27 : 100

Step-by-step explanation:

Given :

__________ no cold ____ cold _____ total

Vitamin C ___ 41 ________ 15 ______ 56

Zinc _______ 12 _________5 ______ 17

Echinacea __ 21 _________ 6 ______ 27

Total ______ 74 _________ 26 ____ 100

The ratio of people who took Echinacea :

Number of people who took Echinacea : total number of people in the survey

From the TOTAL column:

Number of people who took Echinacea = 27

Total Number of people in survey = 100

Hence, ratio equals :

27 : 100

The statements that are necessary and sufficient to prove that ABCD is a parallelogram are, (B), (C) and (D).

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

The area of a parallelogram is base multiples by height as two triangles form a parallelogram.

From the properties of parallelograms the statements that are necessary and sufficient to prove that ABCD is a parallelogram are,

[tex]\overline{AE}[/tex] ≅ [tex]\overline{CE}[/tex] and [tex]\overline{BE}[/tex] ≅ [tex]\overline{DE}[/tex]  as diagonal of a parallelogram bisect each other.

[tex]\overline{AB}[/tex] ≅ [tex]\overline{CD}[/tex] and [tex]\overline{BE}[/tex] ≅ [tex]\overline{CE}[/tex] opposite sides of a parallelogram are equal.

m∠ABC + m∠BAD is 180° as the sum of the adjacent sides in a parallelogram are supplementary.

Answer: I can’t see the shape

Step-by-step explanation:

but I still we help you if you are finding the area if a rectangle, you multiply the length by width. Like if the rectangle length is 7 and the width is 9 they you multiply it together which you get 63. If you are trying to find a area of a triangle then, duplicate the triangle and try to make a rectangle then caculate area of the rectangle and divide that area by two. Like this photo

Answer: [tex]-4,-15;\ \left(-\dfrac{19}{2},-\dfrac{121}{4}\right)[/tex]

Step-by-step explanation:

Given

Function is [tex]F(t)=t^2+19+60[/tex]

Zeroes of the function are

[tex]t^2+19t+60=0\\\\\Rightarrow t=\dfrac{-19\pm\sqrt{19^2-4\times 1\times 60}}{2\times 1}\\\\\Rightarrow t=\dfrac{-19\pm \sqrt{121}}{2}\\\\\Rightarrow t=\dfrac{-19\pm 11}{2}\\\\\Rightarrow t=-4,-15[/tex]

Using completing the square method

[tex]y=t^2+2\times \dfrac{19}{2}t+\dfrac{19^2}{2^2}-\dfrac{19^2}{2^2}+60\\\\y=\left(t+\dfrac{19}{2}\right)^2+60-\dfrac{361}{4}\\\\y=\left(t+\dfrac{19}{2}\right)^2-\dfrac{121}{4}\\\\y+\dfrac{121}{4}=\left(t+\dfrac{19}{2}\right)^2\\\\\left(y-(-\dfrac{121}{4}\right)=\left(t-(-\dfrac{19}{2})\right)^2\\\\\text{The vertex is }\left(-\dfrac{19}{2},-\dfrac{121}{4}\right)[/tex]

Given:

The right angle triangle with legs 4 units and 7 units.

To find:

The length of hypotenuse.

Solution:

Pythagoras theorem: In a right angle triangle,

[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]

Let x be the length of the hypotenuse.

Using the Pythagoras theorem for the given triangle, we get

[tex]x^2=4^2+7^2[/tex]

[tex]x^2=16+49[/tex]

[tex]x^2=65[/tex]

Taking square root on both sides, we get

[tex]x=\sqrt{65}[/tex]                [∵Side length cannot be  negative]

[tex]x\approx 8.06[/tex]

Therefore, the length of the missing side for the given right angle triangle is 8.06 units.

Answer:

Mean: 39  Median: 32.5 Range: 62

Step-by-step explanation:

First, you organize the numbers from least to greatest, so 10  15  19  46  72  72. The median is the middle number, so the average of 19 and 46( 32.5). The Range is the largest number minus the smallest number, so 62. and the mean is all the numbers added up, then divided by the amount of numbers, so 234/6 or 39.

Answer:

a) 5units

b) (4.5, 4)

Step-by-step explanation:

Let the coordinate of P and Q be P(3, 2) and Q(6, 6)

PQ can be gotten using the distance formula;

PQ =√(6-2)²+(6-3)²

PQ = √4²+3²

PQ =√16+9

PQ =√25

PQ = 5units

Midpoint M is  expressed as;

M(X, Y) = {(x1+x2)/2, y1+y2/2}

X = x1+x2/2

X = 3+6/2

X= 9/2

X = 4.5

Similarly;

Y = y1+y2/2

Y = 2+6/2

Y = 8/2

Y = 4

Hence the midpoint of PQ is (4.5, 4)

Answer: A

Step-by-step explanation:

The maximum amount of weight the truck can carry is 1600lbs. You do not want to exceed 1600lbs, but you can reach 1600lbs. This makes the inequality symbol ≤. This symbol says that the weight load has to be less than 1600lbs, but It can equal 1600lbs. You know that the piano is 400lbs and each box is 50lbs. Since you want to figure out how many boxes you can put on the truck alongside the piano, you can use the inequality: 50x + 400 ≤ 1600.

50 represents pounds per/box

x represents the number of boxes you can hold

400 represents the weight of the piano

1600 represents the max weight.
