Answer:

B, 10.5

Step-by-step explanation:

It's actually 10.54, but since you want be to round it, it's 10.5

The daily expense for food and lodging will be 337.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x - μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

A recent survey by the American Automobile Association showed that a family of two adults and two children on vacation in the United States will pay an average of $247 per day for food and lodging with a standard deviation of $60 per day.

Assuming the data are normally distributed if the family had a z-score of 1.5.

Then the daily expense for food and lodging will be

z = (x - μ) / σ

1.5 = (x - 247) / 60

90 = x - 247

x = 247 + 90

x = 337

The daily expense for food and lodging will be 337.

[tex]2x + y = 1[/tex]

Slope intercept form :

[tex]y = - 2x + 1[/tex]

Equation :

[tex]x - 2y = 8[/tex]

Answer:

Step-by-step explanation:

you can re-write 3 1/2 hours into minutes.

1 hr = 60 minutes,

Therefore:

3 1/2 hours = 3.5 times 60 = 210 minutes

So now we have the ratio:

3 1/2 hours : 36 minutes

210 minutes : 36 minutes

Both numbers can be divided by 6

210/6 = 35 and 36/6 = 6

So now we can re-write the ratio as :

35 : 6

Answer:

The first point is right in the origin, so it's (0,0)

Our second point is (2, 1)

Our first point (0,0) would look like if labeled

0(X1) , 0(Y1)

Our second point would look like if labeled

2(X2) , 1(Y2)

Order them to find the slope;

Answer:

y=-4x-8

Step-by-step explanation:

use the equation y-y1=m(x-x1) and solve for y

Answer:

y=-4x-3

Step-by-step explanation:

For this, you would use the point-slope formula, which is (y-y1)=m(x-x1), with x1 and y1 being the coordinates from the ordered pairs, and m being the slope. You can plug the values from the problem into the formula:

(y-5)=-4(x+2)

y-5=-4x-8

y=-4x-3

Answer:

x=3y-2

x+3y=6

if x value is above

place the value of x

3y-2+3y=6

3y+3y_=6+2=8

6y=8

y=8/6=4/3

y=4/3.

x=3,4/3-2

x=12/3-2/1

to make alceeam same 2/1we multiply by 3

The equation of the translated function will be given by f(x) = ( x + 1 ) 2 + 5

The vertex of the original function is (0, 0 )

The vertex of the translated function is (- 1, 5 )

Given f(x) then f(x + a) represents a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

The translated graph has been shifted 1 unit left, thus

f(x) = (x + 1)²

Given f(x) then f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

The translated graph has been shifted 5 units up,

Thus the equation of the translated function will be given by f(x) = ( x + 1 ) 2 + 5

Answer:

10.1119 m or √102.25 m

Step-by-step explanation:

Using our lovely Pythagorean theorem, a² + b² = c², we can find the value of x in this triangle.

Let's say that a = 4.8 and b = 8.9, then set c as x.

(4.8)² + (8.9)² = x²

23.04 + 79.21 = x²

x² = 102.25

x = √102.25

  = 10.111874208...

Answer:

[tex]\sf{x=\dfrac{7}{2}=3.5 }[/tex]

Step-by-step explanation:

It is necessary to isolate the term of x from both sides in order to solve this problem.

First, subtract by 5 from both sides.

2x+5=12

[tex]\sf{2x+5-5=12-5}[/tex]

Solve.

[tex]\sf{12-5=7}[/tex]

2x=7

Divide by 2 from both sides.

2x/2=7/2

Solve.

Dividing is another option.

7/2=3.5

So, the final answer is 7/2=3.5.

First let's calculate the final price at the electronic store.

499.99*(1+0.05)≈524.99

Now let's calculate the final price online

(549.99+22.95)*(1-0.1)≈515.65

If we compare the two we can see that the online price is cheaper at around 515.65 dollar therefore the second choice is correct.
