Answer:

5.5227%

Step-by-step explanation:

Z score formula = (x-μ)/σ

where x is the raw score = < 18.5

μ is the population mean = 26.8

σ is the population standard deviation = 5.2

For x < 18.5

z = 18.5 - 26.8/5.2

z = -1.59615

Probability value from Z-Table:

P(x<18.5) = 0.055227

Converting to percentage

= 0.055227 × 100

= 5.5227%

Therefore, the percentage of young women that are underweight by this criterion is 5.5227%

Step-by-step explanation:no

Answer:

C: 4 hours

Step-by-step explanation:

Mean = Σxn/n

Σx/n = ((2 × 4) + (3 × 5) + (4 × 6) + (5 × 3) + (6 × 3) + (7 × 0) + (8 × 1))/(4 + 5 + 6 + 3 + 3 + 0 + 1)

Σx/n = 88/22

Σx/n = 4 hours

Answer:

X=-8, y=-24

Step-by-step explanation:

Y=3x

x+y=-32

substitute value of y (3x) from first equation to the second equation

x+3x=-32

4x=-32

x=-8

solve for y by putting value of x (-8) into either equation

y=3x

y=3(-8)

y=-24

0r

x+y=32

-8+y=-32

y=-24

Answer:

angle 1=109

Step-by-step explanation:

a straight line =180

Answer:

answer is c

Step-by-step explanation:

angle m5 is 91

angle 1 = 89

angle 5= x

180=89-x

180=89+91

Answer:

c (91)

Step-by-step explanation:

Answer:

14x

Step-by-step explanation:

The (6x+1) = 7 and the other equation also equals 7 so you add together and just ad the x variable since there is no answer

Answer:

Gradient = 2

Step-by-step explanation:

Gradient of a line = Slope of the line

Since, slope of a line passing through two points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Given line in the graph passes through two points (1, 0) and (2, 2)

Therefore, slope or gradient of the line = [tex]\frac{2-0}{2-1}[/tex]

                                                                  = 2

Gradient = 2 will be the answer.

Answer:

choice D) x = 6.6

Step-by-step explanation:

sin 27° = 3/x

0.4540 = 3/x

x = 6.6

Step-by-step explanation:

correct answer is

[tex] \binom{ - 5 \: 2}{6 \: - 2} [/tex]

Answer:

D. 41°

Step-by-step explanation:

[tex](3x + 9) \degree = 132 \degree \\ (vertical \: \angle s) \\ 3x + 9 = 132 \\ 3x = 132 - 9 \\ 3x = 123 \\ x = \frac{123}{3} \\ x = 41 \\ \\ \because m\angle QRS =x\degree \\\therefore m\angle QRS = 41\degree [/tex]

Step-by-step explanation:

Plot the given points and connect in pairs to get a triangle.

Visually we can say it is a right triangle as legs TD and ED seem perpendicular.

Let's confirm this by finding the slopes.

Slope of TD:

Slope of ED:

Product of the slopes is:

This confirms DT⊥ED

Answer:

63m^2 + 18m

Step-by-step explanation:

9m x 7m + 9m x 2  

63m^2 + 9m x 2

the ^2 meaning exponent 2

Answer:

I'm going to guess and say that if HM is one side and OE is the other side of a rectangle, then:

OE = 3 cm

Step-by-step explanation:

36/12 = 3 cm

Answer:Since all the three sides of the triangle are of equal length, we can find the perimeter by multiplying the length of each side by 3. 20 + 20 + 20 = 3 × 20 = 60 cm. Thus, the perimeter of an equilateral triangle is 3 times the length of each side. Area of a two-dimensional shape is the space occupied by the shape.

Answer:

  21.07

Step-by-step explanation:

The tangent ratio is ...

  Tan = Opposite/Adjacent

For the given values, this is ...

  tan(36°) = x/29

Solving for x, we have ...

  x = 29·tan(36°)

  x ≈ 21.07
