Plane A was flying at an altitude of 8 km and Plane B was flying at an altitude of 700 dam. Which plane was flying at a greater altitude?

Answer: B.) 1 and 111 only.

Step-by-step explanation:

75% = 75/100 = 0.75

0.75 falls into the category of rational numbers. Rational numbers comprises of numbers which can be expressed in the form a/b where a and b are integers and B is not 0. Here, both 75 and 100 are integers, thus 75% is a rational number.

Irrational numbers are the opposite of rational numbers thus, 75% is not irrational.

All rational numbers and irrational numbers are REAL numbers, hence, 75% is a real number.

Natural numbers are whole digits starting from 1 e.g ( 1, 2, 3,......). Hence 75% is not a natural number

Whole numbers are natural numbers including 0. (0, 1, 2,.....). Hence, 75% is not a whole number

Integer numbers are comprises of both positive and negative whole numbers. (..., - 1, - 2, 0, 1, 2,...). Hence, 75% is not an integer.

Answer:

[tex]\huge \boxed{\mathrm{12}}[/tex]

Step-by-step explanation:

R is a point on the line segment QS.

QR = 2

RS = 10

QS = 2 + 10

QS = 12

The length of the line segment QS is 12 units.

Given that, point R is on the line segment QS. Given QR =2 and RS = 10.

We need to determine the length of QS.

A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions.

Here, since R is in between QS, QS=QR+RS

=2+10=12 units

Therefore, the length of the line segment QS is 12 units.

Step-by-step explanation:

Hey, there!!

I hope you mean to subtract (-137) +(-43) from sum of -103 and 27.

First, add -103 + 27

[tex] = - 103 + 27[/tex]

[tex] = - 76[/tex]

{As ( minus + plus )= subtracts with sign which has greator value. }

now,

[tex]( - 137) + ( - 43) = - 180[/tex]

{ minus + minus = add with minus sign}.

Now, subtracting -180 from -76.

=(-76) - (-180 )

Now, multiply the sign (- × -)= +

so, -180 becomes +180

= -76+180

= 104..... is answer.

Hope it helps...

Answer:

104

Step-by-step explanation:

With what you provide, the expression would be:

[tex](-103+27)-(-137+-43)[/tex], which equals to:

[tex](-76)-(-180)= (-76)+(180)=104[/tex].      [negative minus a negative equals positive]

So, the answer would be 104.

Answer:

y= -5/3x + 8

Step-by-step explanation:

parallel lines have the same slope

5x + 3y = 6

3y = -5x + 6

y = -5/3x + 2

the new line will have the slope (-5/3x)

y = (-5/3x) + b

plug in the (x, y) value to find b

-2 = -5/3(6) + b

-2 = -10 + b

b = 8

your equation is: y= -5/3x + 8

Answer:

ŷ = 6.69X - 706.18 ; ŷ = 270.56 ; B. The predicted value is not close to the actual diastolic reading.

144

145

Diastolic (y) :

80

106

841

Using the online regression calculator, the regression equation obtained using the data values provided above is:

ŷ = 6.69X - 706.18

Comparing with the regression equation formula: ŷ = mX + c

Where :

ŷ = predicted variable (Diastolic)

m = 6.69 = gradient or slope of the regression line

c = - 706.18 = intercept ( where the regression line intersects the y-axis).

2.) What is the best predicted diastolic pressure for a person with a systolic reading of 146

X = 146

ŷ = 6.69(146) - 706.18

ŷ = 976.74 - 706.18

ŷ = 270.56

The predicted value, 270.56 is not close to the actual Diastolic reading of 91.0

Answer:

The  probability is  [tex]P(14 < X < 20 ) = 0.5354[/tex]  

Step-by-step explanation:

From the question we are told that

   The  proportion that live with their parents is  [tex]\r p = 0.142[/tex]

   The  sample  size is n =  125

Given that there are two possible outcomes and that this outcomes are independent of each other then we can say the Recent census data follows a Binomial distribution

  i.e  

       [tex]X \ \~ \ B( \mu , \sigma )[/tex]

Now the mean is evaluated as

      [tex]\mu = n * \r p[/tex]

      [tex]\mu = 125 * 0.142[/tex]

      [tex]\mu = 17.75[/tex]

Generally the proportion that are not staying with parents is  

      [tex]\r q = 1 - \r p[/tex]

= >    [tex]\r q = 0.858[/tex]

The standard deviation is mathematically evaluated as

     [tex]\sigma = \sqrt{n * \r p * \r q }[/tex]

     [tex]\sigma = \sqrt{ 125 * 0.142 * 0.858 }[/tex]

    [tex]\sigma = 3.90[/tex]

Given the n is large  then we can use normal approximation to evaluate the probability as follows  

     [tex]P(14 < X < 20 ) = P( \frac{ 14 - 17.75}{3.90} <\frac{ X - \mu }{\sigma } < \frac{ 20 - 17.75}{3.90} )[/tex]

Now applying continuity correction

      [tex]P(14 < X < 20 ) = P( \frac{ 13.5 - 17.75}{3.90} < \frac{ X - \mu }{\sigma } < \frac{ 19.5 - 17.75}{3.90} )[/tex]

Generally  

    [tex]\frac{ X - \mu }{\sigma } = Z ( The \ standardized \ value \ of X )[/tex]

    [tex]P(14 < X < 20 ) = P( \frac{ 13.5 - 17.75}{3.90} < Z< \frac{ 19.5 - 17.75}{3.90} )[/tex]

     [tex]P(14 < X < 20 ) = P( -1.0897 < Z< 0.449 } )[/tex]

    [tex]P(14 < X < 20 ) = P( Z< 0.449 ) - P(Z < -1.0897)[/tex]

So  for the z -  table  

         [tex]P( Z< 0.449 ) = 0.67328[/tex]

         [tex]P(Z < -1.0897) = 0.13792[/tex]

 [tex]P(14 < X < 20 ) = 0.67328 - 0.13792[/tex]    

  [tex]P(14 < X < 20 ) = 0.5354[/tex]  

Answer:

C

Step-by-step explanation:

The definition of a limit is the value a function it is approaching as the limit approaches a certain point.

We have the limit:

[tex]\lim_{x\to3} f(x)=5[/tex]

In other words, the value of f(x) as x approaches 3 approaches 5.

We do not care what happens at x=3. Rather, the limit tells us that as x approaches or gets closer to x=3, the function f(x) gets closer to 5.

Thus, the correct answer is C.

Answer:

16Km due east of school P

Step-by-step explanation:

Given

A school P is 16km due west of a school Q

Thus, we can say that distance PQ = 16 km.

________________________________

now we have to find  the bearing of Q from P​

As distance is same

distance PQ = distance QP

Thus,

Distance will remain same of 16 km.

For direction,

If Q is west of P, then P will be east of Q[tex]P------------------>Q[/tex]

as shown in figure P is west of Q,

now from point P , Q is west P.

Thus,

Bearing of  School Q from P is 16Km due east of school P

When n < 1, Declan's statement is incorrect because 4 * 0 = 0 which is not greater than 4 and this continues for all n values that are less than 1.

Step-by-step explanation:

first you group like terms.

-3s-s+8+1-2

-4s+7

Answer:

-4s + 7

Step-by-step explanation:

We need to combine like terms. Like terms are terms whose variables (and exponents) are the same (note that they could be constants as well). Basically, they are "like" each other. In this case, the like terms are -3s and - s and also 1, 8, and -2. -3s - s = -4s and 1 + 8 - 2 = 7 so the answer is -4s + 7.

a is negtive  bcs grph opens down. h value is -1 and k is +2

Answer:

[tex]\frac{3}{13} i+\frac{11}{130} j-\frac{6}{65} k\\[/tex]

Step-by-step explanation:

Given A = 5i + 11j – 2k and B = 4i + 7k​, the vector projection of B unto a is expressed as [tex]proj_ab = \dfrac{b.a}{||a||^2} * a[/tex]

b.a = (5i + 11j – 2k)*( 4i + 0j + 7k)

note that i.i = j.j = k.k  =1

b.a = 5(4)+11(0)-2(7)

b.a = 20-14

b.a = 6

||a|| = √5²+11²+(-2)²

||a|| = √25+121+4

||a|| = √130

square both sides

||a||² = (√130)

||a||²  = 130

[tex]proj_ab = \dfrac{6}{130} * (5i+11j-2k)\\\\proj_ab = \frac{30}{130} i+\frac{11}{130} j-\frac{12}{130} k\\\\proj_ab = \frac{3}{13} i+\frac{11}{130} j-\frac{6}{65} k\\\\[/tex]

Hence the projection of b unto a is expressed as [tex]\frac{3}{13} i+\frac{11}{130} j-\frac{6}{65} k\\[/tex]

Answer:

296.5 miles

Step-by-step explanation:

Round trip distance of City X to City Y is 647 miles.

Round trip includes to and fro.

i.e. City X to City Y and then City Y to City X back.

Let the distance between City X and City Y = D

Distance traveled in round trip between City X and City Y = D + D = 2D

Given than 2D = 647

OR

D = [tex]\frac{647}2[/tex] = 323.5 miles

Kindly refer to the attached diagram, for the location of City Z.

Distance between XY = Distance from X to Z + Distance from Z to Y.

Distance XY = XZ +ZY

323.5 = 27 +ZY

ZY =296.5 miles
