a) Complete the Venn diagram.
The universal set, &, contains all of the
25 students.
[3]
b) One of these students is chosen at random.
What is the probability that this person plays football?

Answers

Answer 1

Answer:

a) see explanation

b) 40%

Explanation:

a) sorry, i can't specifically help with this one unless you attach a picture of the venn diagram. but the way venn diagrams work is that you draw several circles, each representing a trait (i.e. plays rugby). circles will overlap if someone has more than one trait (i.e. plays both sports).

b) the probability is 10 ÷ 25 × 100% = 40%.

i hope this helps! :D

Sam and Dave, who are both Park Rangers, each manage a nature preserve. ​ ​Devin's nature reserve is 14 hectares and Sam's nature reserve is 14\cdot 10^{6}14⋅10 6 square meters. ​Who manages the smaller nature preserve? Note: 1 hectare = 10,000 square meters

Answers

Answer: Devin's

Step-by-step explanation:

Given

Devin's nature reserve is 14 hectares

Sam's nature reserve is [tex]14\times 10^6\ m^2[/tex]

Also, [tex]1\ \text{hectare}=10,000\ m^2[/tex]

Devin reserve in square meter [tex]14\ \text{hectares}=14\times 10^4\ m^2[/tex]

Clearly, [tex]14\times 10^6> 14\times 10^4[/tex]

So, Devin's manages smaller area

Una parcela de forma cuadradra mide 1089km2 de superficie cuantos metros mide el lado de la parcela

Answers

Respuesta:

3.3 × 10⁴ m

Explicación paso a paso:

Paso 1: Información provista

Superficie de la parcela cuadrada (S): 1089 km²

Paso 2: Determinar la longitud del lado (l) de la parcela

Podemos determinar la superficie de un cuadrado usando la siguiente fórmula.

S = l²

l = √S = √1089 km² = 33 km

Paso 3: Convertir "l" a metros

Vamos a usar el factor de conversión 1 km = 10³ m.

33 km × 10³ m/1 km = 3.3 × 10⁴ m

Write an equation in standard form for a line that is perpendicular to the line with an equation of y = 3x —5 that passes through the point (8, 5).

Answers

Answer:

x + 3y = 23

Step-by-step explanation:

m = -1/3, find 'b'

5 = -1/3(8) + b

15/3 = -8/3 + b

23/3 = b

y = -1/3x + 23/3

multiply each side by 3 to get:

3y = -x + 23

x + 3y = 23

A delivery company is logging the number of miles each employee drives each day. The company found an average of about 85.6 miles. Assume that the standard deviation is 9.85 miles and that a random sample of 50 drivers was used to determine the average. Which statements are true about this situation?
1.)The 99% confidence interval is from about 81.43 to 90.58 miles.
2.)The 95% confidence interval is from about 82.87 to 88.33 miles.
3.)The margin of error for 95% confidence is about 2.52 miles.
4.)The sample isn’t large enough to use a normal distribution.
5.)The margin of error for 99% confidence is about 3.59 miles.
There are multiple answers

Answers

The correct answer is: (the margin of error for 99% confidence is about 3.59 miles.

The delivery company's statistics on the average driving miles show that the true statements are:

95% confidence interval ... 82.87 to 88.33 miles.Margin of error 99% confidence ... 3.59 miles.

What is the 99% confidence interval?

Z score for 99% confidence interval is 2.576 so this can be found as:

= 85.6 ± (2.576 x 9.85) / √50

= (82.01 to 89.19)

What is the 95% confidence interval?

Z score for 95% confidence interval is 1.960 so this can be found as:

= 85.6 ± (1.96 x 9.85) / √50

= (82.87 to 88.33)

What is the 95% confidence margin of error?

With a Z score of 1.960:

= (1.96 x 9.85) / √50

= 2.70 miles

What is the 99% confidence margin of error?

= (2.576 x 9.85) / √50

= 3.59 miles

The correct options are therefore 2 and 5.

Answers

Answer:

176.25in^2

Step-by-step explanation:

You can tell that the two triangles on the left, and the two triangles on the right make a rectangle if you flip one of them. Because of this, you can multiply the base and height to get the area of both.

7.5*16=120 (left side)

7.5*7.5=56.25 (right side)

Now we add them to get the full area:

120+56.25=176.25in^2

Difference between 3/5 of Raman's present age and his age 4 years ago is zero. What will be his age after 5 years?

Answers

Answer: 15 years

Step-by-step explanation:

Given

Difference between [tex]\frac{3}{5}[/tex] Raman's present age and his age 4 years ago is 0

Suppose Raman's present age is [tex]x[/tex]

So, we can write

[tex]\Rightarrow \dfrac{3x}{5}-(x-4)=0\\\Rightarrow \dfrac{3x-5x}{5}+4=0\\\Rightarrow \dfrac{-2x}{5}+4=0\\\Rightarrow x=\dfrac{20}{2}=10[/tex]

His age after 5 years is [tex]x+5=15\ yr[/tex]

~Thanks in advance! :D ​

Answers

Answer:

Solution given:

A(a,b) lie in 6x-y =1

substituting value of A in equation ,we get

6a-b=1...................(1)

B(b,a) lie in 2x - 5y = 5

substituting value of B in equation ,we get

2b-5a=5

b=5(a+1)/2............(2)

substituting value of b in equation 1 ,we get

6a-5(a+1)/2=1

12a-5a-5=2

7a=2+5

a=[tex] \frac{7}{7} [/tex]=1

substituting value of a in equation 1 ,we get

6×1-b=1

6-1=b

b=5

so points are A(1,5) and B(5,1)

we have
