Answer:

Yes

Step-by-step explanation:

Because A categorical variable can bexpressed as a number when statistical evaluation is intended, However, these numbers do not mean the same as a numerical value e.g giving numbers to waist sizes, test scores, grade level etc

Answer:

y + 5 = (-13/4)(x - 3)

Step-by-step explanation:

Going from (-1, 8) to (3, -5), x (the 'run') increases by 4 and y (the 'rise') decreases by 13.  Thus, the slope of the desired line is m = rise / run = -13/4.

The point-slope formula is

y - k = m(x - h), and here m = -13/4, k = -5 and h = 3:

y + 5 = (-13/4)(x - 3)

Answer:

P( 43 ≤ X ≤ 49) = 0.9545

Step-by-step explanation:

We are given mean of 46 and a standard deviation of 3

We want to find the percentage of daily phone calls numbering between 43 and 49. This can be written as;

P( 43 ≤ X ≤ 49)

Using the z-formula, we have;

z = (x - μ)/s

This transforms to;

P((43 - 46)/3)) ≤ Z ≤ ((49 - 46)/3))

This gives;

P(-2) ≤ Z ≤ P(2)

From z - table attached, P(-2) = 0.02275 and P(2) = 0.97725

Thus;

P( 43 ≤ X ≤ 49) = 0.97725 - 0.02275

P( 43 ≤ X ≤ 49) = 0.9545

Answer:

i think sorry if im wrong

Step-by-step explanation:

Answer:

9.22

Step-by-step explanation:

The calculation of z is shown below:-

Given that

2x-4y+4z-6w=4 .... (1)

6w-4x+4y-4z=-12 ..... (2)

6w+4x-2y+6z=64 ...... (3)

4z+2w+6y-4x=56 .... (4)

Here we need to decrease the equations with the help of canceling out a few variables.

Now we need to add equations 1 and 2 that is

(2x - 4x) + (-4y + 4y) + (4z - 4z) + (-6w + 6w) = 4 + 12

Now we solve the above equation

-2x + 0 = 16

-2x = 16

x = -8

Now, equation 2 minus 3

6w - 6w + (-4x - 4x) + 4y + 2y + (-4z - 6z) = 12 - 64

-8x + 6y - 10z = -52

Now we will put the value of x

-8(-8) + 6y - 10z = -52

64 + 6y - 10z = -52

6y - 10z  = -52 - 64

6y - 10z = -116

3y - 5z = -58 ... 5

Equation 3 × 1 and equation 4 × 3

6w + 4x - 2y + 6z = 64 ..... (3)

4z + 2w + 6y - 4x = 56 .... (4)

6w + 4x - 2y + 6z = 64

12z + 6w + 18y - 12x = 168

Now we will subtract both equations that are

16x - 20y - 6z = -104

8x - 10y - 3z = -52

8(-8) - 10y - 3z = -52

-64 - 10y - 3z = -52

-10y - 3z = -52 + 64

-10y - 3z = 12 ....... (6)

equating 5 and 6 and solving that is

3y - 5z = -58 ... 5 × 10

-10y - 3z = 12 ....... 6 × 3

30y - 50z = -580

-30y - 9z = 36

we will add both equation

-50z - 9z = -580 + 36

-59z = -544

z = -544 ÷ -59

After solving z value we will get

= 9.22

Step-by-step explanation:

One side of a triangle is 9 cm and other side is 37 cm. We need to find what could be the length of the third side of the triangle.

If we add one and other side i.e. 9 cm + 37 cm = 46 cm

If we subtract one and other side i.e. 37 cm - 9 cm = 28 cm

We know that, the length of the third side must be less than the sum of the other two sides and greater than the difference between the other two sides.

Thus, the third side could be between 46 cm and 28 cm.

Answer:

19.8

Step-by-step explanation:

Answer:

26

Step-by-step explanation:

When we find the values of questions like this, we have to remember to use "PEMDAS".

Because multiplication comes before addition, we have to multiply first.

(Since there are two multiplication parts in the question, we start off by the first one.)

When we multiply both parts, we'll get:

[tex](18)+(8)[/tex], which equals to 26.

So, your answer is 26.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = - 19}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 3 = 12x - 5(2x - 7)}[/tex]

Distribute 5 through the parentheses

⇒[tex] \sf{ - 3 = 12x - 10x + 35} [/tex]

Collect like terms

⇒[tex] \sf{ - 3 = 2x + 35}[/tex]

Swap the sides of the equation

⇒[tex] \sf{2x + 35 = - 3}[/tex]

Move 45 to right hand side and change it's sign

⇒[tex] \sf{2x = - 3 - 35}[/tex]

Calculate

⇒[tex] \sf{2x = - 38}[/tex]

Divide both sides of the equation by 2

⇒[tex] \sf{ \frac{2x}{2} = \frac{ - 38}{2} }[/tex]

Calculate

⇒[tex] \sf{x = - 19}[/tex]

Answer:

[tex] x = 10 [/tex]

m<CQF = 32°

m<AQE = 32°

Step-by-step explanation:

m<CQB = m<CQA = 90° (right angle)

m<CQB = m<CQF + m<FQB

m<CQF = 3x + 2

m<FQB = 58°

Therefore,

[tex] 90 = 3x + 2 + 58 [/tex]

Solve for x:

[tex] 90 = 3x + 60 [/tex]

[tex] 90 - 60 = 3x + 60 - 60 [/tex]

[tex] 30 = 3x [/tex]

[tex] \frac{30}{3} = \frac{3x}{3} [/tex]

[tex] 10 = x [/tex]

[tex] x = 10 [/tex]

m<CQF = 3x + 2

Plug in the value of x to find m<CQF

m<CQF = 3(10) + 2 = 30 + 2

m<CQF = 32°

m<CQF and m<AQE are vertical opposite angles, therefore, they are congruent.

Thus,

m<AQE = 32°

Answer:

x = 10

m∠CQF = 32

m∠AQE = 58

Answer:

49 -- No. 71 U.S. Naval Base, Guantanamo Bay

Step-by-step explanation:

Answer:

6 hours 15 minutes

Step-by-step explanation:

1 litre = 1000cm³

45 litres = 45000cm³

Volume = rate × time

45000 = 2 × t

t = 22500 secs

= 375 mins

BRAINLIEST PLEASE

All time values listed above are equivalent, so you only need to pick one value to write as the answer.

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

Work Shown:

1 liter = 1000 cubic cm

45 liters = 45*1000 = 45000 cubic cm

The container has a capacity of 45000 cubic cm

It will take 45000/2 = 22500 seconds to fill the container since the rate is 2 cubic cm per second.

-----------------

Convert from seconds to minutes

22500 seconds = (22500)*(1 min/60 sec)

22500 seconds = (22500/60) min

22500 seconds = 375 min

-----------------

Convert to hours

375 min = (375)*(1 hr/60 min)

375 min = (375/60) hr

375 min = 6.25 hr

----------------

Converting to hours,minutes

6.25 hr = 6 hr + 0.25 hr

6.25 hr = 6 hr + (0.25*60) min

6.25 hr = 6 hr + 15 min

6.25 hr = 6 hr, 15 min

Answer:

A: 12.5 per week B= 12.75

Step-by-step explanation:

1/2 times 7 (days in a week) is 3.5. So A is 8+3.5=12.5. 7 times 5/4 is 8.75. So B is 4+8.75=12.75

Answer:

[tex]22.805 < \mu < 24.575\\[/tex]

Step-by-step explanation:

Given parameters

Z interval E = (23.305,25.075)

mean xbar = 23.69

number of samples n = 30

Required

we are to find the confidence interval for the Z interval given.

The formula for finding the confidence interval is expressed as shown below;

[tex]\overline x - E < \mu < \overline x + E[/tex] where;

xbar is the mean = 30

E is the margin of error

[tex]E = \frac{U-L}{2}[/tex]

U =  upper limit = 23.305

L = lower limit = 25.075

[tex]E = \frac{25.075-23.305}{2}\\E = \frac{1.77}{2}\\E = 0.885[/tex]

The confidence interval is therefore expressed as [tex]23.69 - 0.885 < \mu < 23.69+ 0.885\\22.805 < \mu < 24.575\\[/tex]

Hence the confidence interval is expressed as [tex]22.805 < \mu < 24.575\\[/tex]

Answer:

50

Step-by-step explanation:

a = # of apples

b = # of bananas

5a + 3b = 570

3a + 5b = 470

Solve with substitution or elimination.  To solve by elimination, multiply the first equation by 5 and the second equation by 3.

25a + 15b = 2850

9a + 15b = 1410

Subtract:

16a = 1440

a = 90

Plug into either equation to find b.

5(90) + 3b = 570

450 + 3b = 570

3b = 120

b = 40

So apples are 90 cents, and bananas are 40 cents.  Therefore, apples are 50 cents more than bananas.

Answer:

The value of [tex]x(y-z)^2[/tex] is -16.

Step-by-step explanation:

We need to evaluate [tex]x(y-z)^2[/tex] for x = -1, y = 5 and let us assume that z = 1

It can be simply done by putting the values of x,y and z in the given expression.

[tex]x(y-z)^2=(-1)(5-1)^2\\\\=-1(4)^2[/tex]

We know that the value of 4² = 16

So,

[tex]x(y-z)^2=16\times -1\\\\=-16[/tex]

So, the value of [tex]x(y-z)^2[/tex] is -16.

Answer:

Step-by-step explanation:

Probability is defined as the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome

probability = n{E}/n{S}

n(E) is the total number of events

n{S} is the total number of sample space.

For a coin that is tossed 3times, the possible outcome are:

S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

The total number of sample space is n(S) = 2³ = 8

n{S} = 8

a) probability of getting two heads.

Events E = {HHH, HHT, HTH, THH}

n(E) = 4

Pr(getting two heads) = 4/8 = 1/2

b) probability of getting one head.

Events E = {HTT, THT, TTH}

n(E) = 3

Pr(getting one head) = 3/8

c) probability of getting at least one head means probability of getting 1 head and more but not less than a head.

Events E = {HHH, HHT, HTH, HTT, THH, THT, TTH}

n(E) = 7

Pr(getting at least one head) = 7/8

d) probability of getting at least two heads means probability of getting 2 head and more but not less than 2 head.

Events E = {HHH, HHT, HTH, THH}

n(E) = 4

Pr(getting at least two head) = 4/8 = 1/2

Answer:

(t•s )(x) = 4x^3 - 29x^2 + 10x - 21

Step-by-step explanation:

(t•s )(x) is the product of functions s and t:

(t•s )(x) = ( 4x^2 - x + 3)(x - 7).  Applying the Distributive Property of Multiplication, we get:

(t•s )(x) = 4x^3 - 28x^2 - x^2 + 7x + 3x - 21

which needs to be simplified by combining like terms:

(t•s )(x) = 4x^3 - 29x^2 + 10x - 21
