Answer:

∡A = 48°

∡B = 58°

∡BCA = 74°

Step-by-step explanation:

start by finding m∡BCA; this angle is supplementary with ∡BCD and the pair must add up to 180. therefore, m∡BCA = 74°

all three interior angles of a triangle must add up to 180:

74 + 4y + 3y + 22 = 180

96 + 7y = 180

7y = 84

y = 12

substitute '12' for 'y' in 3y + 22 to get 58

substitute '12' for '4y' to get 48

Answer:

$90.75

Step-by-step explanation:

First we convert kilograms to pounds.

1 kg = 2.2 lb

15 kg = 15 * 2.2 lb = 33 lb

Cost of shipping: $2.75/lb

Cost of shipping 33 lb: 33 lb * 2.75/lb = $90.75

Answer: $90.75

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

32.3 , 28.8 , 29.1 , 29.5 , 30.8 , 31.0 , 17.5 , 34.5 , 23.5 , 33.0 , 31.7 , 28.6 , 27.4

Reordered data:

17.5, 23.5, 27.4, 28.6, 28.8, 29.1, 29.5, 30.8, 31.0, 31.7, 32.3, 33.0, 34.5

The mean ; m

Mean, m = Σx /n

Σx = 377.7

n = sample size = 13

m = Σx / n = 377.7 / 13 = 29.05

Median = 1/2(n+1)th term

= 1/2(14) = 7th term = 29.5

Range = maximum - minimum

Range = 34.5 - 17.5 = 17

Lower quartile (Q1) = 1/4(n+1)th term

1/4(14)th term = 3.5th term

(3rd + 4th) / 2

= (27.4 + 28.6) / 2

= 28

Upper quartile (Q3) = 3/4(n+1)th term

3/4(14)th term = 10.5th term

(10th + 11th) / 2

= (31.7 + 32.3) / 2

= 32

IQR = Q3 - Q1

IQR = 32 - 28 = 4

Variance : (V) = Σ(x - m)²/n-1

[(32.3-29.05)^2 +(28.8-29.05)^2 + (29.1 - 29.05)^2 + (29.5-29.05)^2 + (30.8-29.05)^2 + (31.0-29.05)^2 + (17.5 - 29.05)^2 + (34.5-29.05) ^2 + (23.5-29.05)^2 + (33.0-29.05)^2 + (31.7-29.05)^2 + (28.6-29.05)^2 + (27.4 - 29.05)^2] / 12

Variance = 19.76

Standard deviation = sqrt(variance)

Standard deviation = sqrt(19.76)

Standard deviation = 4.45

Answer:

It will be 5:2 or 2:5

Answer:27.1c

Step-by-step explanation:

18.6 + 8.5 =27.1

Answer:

27.1

Step-by-step explanation:

Answer:  approximately 3.57 seconds

========================================================

Work Shown:

x = number of seconds

distance = speed*time

250 meters = (70 m/s)*(x seconds)

250 = 70x

70x = 250

x = 250/70

x = 3.57142857142858

x = 3.57

It takes approximately 3.57 seconds for the car to travel 250 meters, when it travels a constant speed of 70 meters per second.

Answer:

A rational number is any number that can be expressed as a ratio of two integers (hence the name "rational"). ... For example, 1.5 is rational since it can be written as 3/2, 6/4, 9/6 or another fraction or two integers. Pi (π) is irrational since it cannot be written as a fraction

Answer:

Step-by-step explanation:

From the given information:

Note that the possible values of Y are 0 and 1 because;

y = 0 if X = 0 and y = 1 if X = ±1

∴

[tex]P(Y =0) = P(X = 0) =\dfrac{1}{3}[/tex]

[tex]P(Y = 1) = P(X = -1 \ or \ 1) \\ \\ = P(X = -1) + P(X = 1)[/tex]

[tex]= \dfrac{1}{2}+ \dfrac{1}{6}[/tex]

[tex]=\dfrac{3+1}{6}[/tex]

[tex]= \dfrac{2}{3}[/tex]

b)

[tex]E(|X|) = \sum |x| P(X=x) = ( 1 \times \dfrac{1}{2}) + ( 0\times \dfrac{1}{3}) + ( 1 \times \dfrac{1}{6})[/tex]

[tex]= \dfrac{2}{3}[/tex]

Answer:

For the substance to decay to one-half of its original amount, it will take:

10.6 weeks.

Step-by-step explanation:

The decay rate = dQ/dt= -rQ

Where r > 0.

100 mg of a mystery substance decays to 81.14 mg in 4 weeks

This implies that it has decayed by 18.86 mg (100 - 81.14) in 4 weeks

The rate of decay per week = 4.715 mg (18.86 mg/4)

For the substance to decay to one-half of its original amount, i.e. 50 mg (100 mg/2), it will take 10.6 (4/18.86 * 50) weeks.

We can also determine the time it will take the substance to decay by working with the decay rate and the volume of decay, thus:

Decay rate = 4.715 / week

Decay volume = 50 mg (100 mg/2)

Time for 50 mg to decay = Decay volume/Decay rate

= 50 mg/4.715

= 10.6 weeks

Answer:

1/4

Step-by-step explanation:

3/12 ÷3= 3÷3=1 and 12÷3=4

We have that for the Question ,it can be said that the next 3 sequence is

Respectively

Generally

We notice that the difference between numbers in the sequence rises by 4

therefore

For the first differ

9-2=7

7+4=11

Hence

11+9=20

Generally

for the sixth value

4*5=20

20+7=27

27+77=104

Therefore

the next 3 sequence is

Respectively

Step-by-step explanation:

The Probability that Ginger will eat pizza for lunch every day for next week is 0.2.

Probability is "possibility that deals with the occurrences random event. It values varies from 0 to 1".

According to the question,

Ginger assigns digits 0 and 1 = no Pizza available and also assign digits

2,3,4,5,6,7,8 and 9 = Pizza available.

The table shows the results of the simulation,

08458 this simulation contains digit '0' so there is no pizza.

47165 this simulation contains digit '1' so there is no pizza.

68194 this simulation contains digit '1' so there is no pizza.

88490 this simulation contains digit '0' so there is no pizza.

01841 this simulation contains digits '0 and 1' so there is no pizza.

43226this simulation contains no digits '0 and 1' so there is pizza available.

12924 this simulation contains digit '1' so there is no pizza.

52568 this simulation contains no digits '0 and 1' so there is pizza available.

93039 this simulation contains digit '0' so there is no pizza.

39406this simulation contains digit '0' so there is no pizza.

Total number of simulation = 10.

Formula for Probability = [tex]\frac{Number of favorable events }{Total number of outcomes}[/tex]

Probability of availability of Pizza = [tex]\frac{2}{10}[/tex] = [tex]\frac{1}{5}[/tex] = 0.2.

Hence, the Probability that Ginger will eat pizza for lunch every day for next week is 0.2.
