Flying with the wind a plane went 386 km/h. Flying into the same wind the plane only went 318 km/h. find the speed of the plane
zysi [14]

Answer:

Speed of plane  in air is  352 km/hr and speed of wind is 34 km/hr

Step-by-step explanation:

Average speed of plane in with wind = 386 km/h

Average speed of plane against wind = 318 km/hr

Consider the speed of plane in wind be  x km/hr and speed of plane against wind  be  y  km/hr

As such speed of plane in wind would be  x + y km/hr and speed of plane  against wind would be  x - y km/hr. i.e

x+y = 386

x-y = 318

by solving these two equation, we get

2x=704

x= 352 km/hr

y=386 - 352

y= 34 km/hr

Hence, Speed of plane  in air is  352 km/hr and speed of wind is 34 km/hr

HELP!!!!!!!
lesantik [10]

Answer:

Option A, Left by 4 units

Step-by-step explanation:

<u>Step 1:  Convert g(x) to a function square</u>

We currently have g(x) in this order:  ax^2 + bx + c

However, we want g(x) to be in this order:  (ax + c)^{2}

The first thing we have to do is to factor it out:

g(x)=x^{2}+8x+16

g(x) = (x + 4)(x + 4)

g(x) = (x+4)^{2}

<u>Step 2:  Now we can see which way we need to move it</u>

The original form is:  f(x) = (ax - b)^{2}

Since the - has changed to a +, that means that we moved -4 spaces down the x-axis.  This means that we move left by 4 units.

Answer:  Option A, Left by 4 units

We expect that students who do well on the midterm exam in a course will usually also do well on the final exam. Gary Smith of P
dybincka [34]

Using the model equation, the predicted mean score on the final given a score of <em>10 points above the class mean</em> in the mid term exam is 50.7

<u>The Least - Square Regression equation which models the relationship between midterm and final exam score is</u> :

  • γ=46.6 + 0.41x

x = 10 points ; <u>substitute the value of x = 10 into the regression equation</u> ;

γ=46.6 + 0.41(10)

γ=46.6 + 4.1

γ = 50.7

The <em>number of points above the mean</em> he'll score in the final exam is predicted to be 50.7
