Answer:

7/10

Step-by-step explanation:

For a person to use at least two of the facilities means they can use the three facilities as well.

Let n(U) be the total people in the sport centre = 100

n(G) be people that uses gym = 67

n(S) be people that uses swimming pool = 62

n(T) be people that uses track = 56

n(GnP) be gym and pool = 38

n(PnT) be people that use the pool and the track = 31

n(GnT) be people that use the gym and the track = 33

n(GnPnT) be people that use all three facilities = 16

People that uses gym and pool only = n(GnP) - n(GnPnT)

= 38-16

= 22

People that uses pool and track only = n(PnT) - n(GnPnT)

= 31-16

= 15

People that uses gym and track only = n(GnT) - n(GnPnT)

= 33-16

= 17

Total people that uses at least 2 facilities = 16+22+15+17 = 70

Probability that this person uses at least 2 facilities = Total people that uses at least 2 facilities/Total people in the sport centre

Probability that this person uses at least 2 facilities = 70/100 = 7/10

Answer:

75,900 g

Step-by-step explanation:

m=d×v

(1.38g/cm^3) × (55,000)

The mass of the drum is 75.9 kg.

The mass of the drum is the product of the volume and density of the drum.

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have been given that the plastic shreds were placed into 55-liter drums.

We have to determine the mass of the plastic shreds inside one of the drums in kg.

Here density of the drum = 1.38g/cm³ and the volume of the drum = 55,000

The mass of the drum = (1.38g/cm³) × (55,000)

The mass of the drum = 75,900 g

The mass of the drum = 75.9 kg

Answer:

Line TU is parallel to line RS

Step-by-step explanation:

I just got a 100 on the test

Line TU is parallel to line RS and has a slope of -1/5

A linear equation is in the form:

y = mx + b

Where m is the slope and b is the y intercept.

Line V W goes through (-1, 5) and (1, 5). Line R S goes through (-5, 3) and (5, 1). Line T U goes through (-1,-2) and (4, -3).

Slope of VW = (5 - 5)/(1- (-1)) = 0

Slope of RS = (1 - 3) / (5 -(-5)) = -1/5

Slope of TU = (-3 - (-2))/(4 - (-1)) = -1/5

Line TU is parallel to line RS and has a slope of -1/5

Answer:

Neither parallel nor perpendicular

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Define lines

y = 2x + 4

y = -2x + 4

Parallel lines have the same slope but different y-intercepts. If the 2 lines were parallel, their m value would be the same. If the original line's slope is 2, the parallel line's slope would also be 2. Therefore, they aren't parallel.

Perpendicular lines have the negative reciprocal of the original slope. If the 2 lines were perpendicular, one slope would be 2 and the other slope would be -1/2. Therefore, they aren't perpendicular.

Therefore, our answer is neither parallel nor perpendicular.

Answer:

Neither parallel nor perpendicular.

Step-by-step explanation:

y =  2x +4

y = -2x + 4

The 2 slopes are 2 and -2.

If they were equal the 2 lines would be parallel.

If  they had the relationship  slope1 * slope2 = -1 they would be perpendicular.

They are neither so its the last choice.

Step-by-step explanation:

We should use this function to find the standard form the line :

[tex]y - y(given \: point) = (gradient) \times ( \: x - x(g \: p) \: ) \\ y - 4 = 5 \times (x - 3) \\ y - 4 = 5x - 15[/tex]

Answer:

California's rate for heart disease is more extreme than Cancer

Step-by-step explanation:

Given

Represent Cancer with C and Heart Disease with H

H = 143

C = 137

Population = per 100,000

First we need to determine the probability of both.

For H

P(H) = H/100000

P(H) = 143/100000

P(H) = 0.00143

For C

P(C) = C/100000

P(C) = 137/100000

P(C) = 0.00137

By comparison,

0.00143 > 0.00137

So, California's rate for heart disease is more extreme than Cancer.

Reason: P(H) > P(C)

Step-by-step explanation:

-0.71

The r - value -0.71 represents the strongest correlation which is negative correlation.

The correlation coefficient is a quantitative method of calculating correlation. It is a statistical concept, which helps in establishing a relation between predicted and actual values obtained in a statistical experiment.

For the given situation,

The options has the r - values, we need to check which option represents the strong correlation.

Now., The relationship between two variables is generally considered strong when their r value is larger than 0.7.

A correlation of r = -0.71 suggests a strong, negative association between two variables.

A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.

Hence, we can conclude that the r - value option (D) -0.71 represents the strongest correlation which is negative correlation.

Answer:

a. -7

b. -25

c. 27

d. 15

Step-by-step explanation:

The solution of expression is a) 13 + (-20) = -7

b) (-14) + (-11) = -25

c) 18 - (-9) = 27

d) (-21) - (-36) = 15

a) 13 + (-20) = -7

To add a positive number and a negative number, we subtract the absolute values and use the sign of the number with the greater absolute value.

b) (-14) + (-11) = -25

When adding two negative numbers, we simply add their absolute values and retain the negative sign.

c) 18 - (-9) = 27

Subtracting a negative number is equivalent to adding its positive value. Therefore, 18 - (-9) becomes 18 + 9, which equals 27.

d) (-21) - (-36) = 15

Similar to the previous example, subtracting a negative number is equivalent to adding its positive value. (-21) - (-36) becomes (-21) + 36, which equals 15.
