In conclusion  the value that correctly fills in the blank in the table is 0.69.

Why it is?

To find the relative frequency of boys, we need to use the information given in the frequency table. We know that the total number of boys is 120 - 37 = 83, since the total number of students is 120 and the number of girls is 37.

We can then calculate the relative frequency for boys by dividing the number of boys who prefer math or social studies (40 + 43 = 83) by the total number of students (120):

Relative frequency for boys = (40 + 43) / 120 ≈ 0.69

Rounding to the nearest hundredth, we get:

Relative frequency for boys ≈ 0.69

Therefore, the value that correctly fills in the blank in the table is 0.69.

Answer:

(A) The lines L1 and L2 are NOT parallel

(B) The lines DON'T intersect

(C) The lines ARE skew

Step-by-step explanation:

L1: x=26+7t; y=8+3t; z=18+5t

L2: x=-11+8t; y=-11+5t; z=-13+8t

TEST FOR PARALLEL

The direction vector for L1 is (7,3,5)

The direction vector for L2 is (8,5,8)

Since 8 is not a multiple of 7,

5 is not a multiple of 3,

and 8 is not a multiple of 5; both direction vectors are NOT propositional.

The lines are hence unparallel lines. They do not move in the same direction.

TEST FOR INTERSECTION

We equate the functions of X, the functions of Y or the functions of Z, and substitute the value of t gotten, into another equation herein.

26 + 7t = -11 + 8t

7t - 8t = -11 - 26

-t = -37

t = 37

Substituting 37 for t in equation 3, we have

18+5(37) = -13+8(37)

18+185 = -13+296

203 = 283

Obviously, 203 is not equal to 283

These 3 equations aren't consistent, so the lines don't intersect or cross paths. Lines L1 and L2 are skew.

The function f(x)* = 1 + x^2 is defined for all real numbers x, so the domain is all real numbers, or (-∞, ∞).

In determining the function's output values, one must consider its collection of feasible results to extract the range. Reviewing f(x)* exhibits a minimum value of 1 due to x^2 being perpetually non-negative, while adding another factor merely preserves positivity.

Concurrently as x skyrockets, so too does the value of f(x)* given that approaching infinity generates infinitely larger powers than any constant coefficient subordinated by it. Consequently, the overall range of f(x)* becomes [1, ∞), enwrapping all feasible solutions equivalent or superior to 1.

The correct the correct multiple of ( 52 x 4 ) is 208.

The number you obtain when you multiple a certain number by an integer. Multiple as like consisting of, including, or involving more than one.

Assume the multiplication of 52 x 4 is A.

To find the value of A

52 x 4 = ( 50 + 2 ) x 4

52 x 4 = 50 x ( 4 ) + ( 2 ) x 4

52 x 4 = ( 200 ) + 8

52 x 4 = ( 208 ).

A = 208.

$2.89

Step-by-step explanation:

7.6% of $37.99 is 2.88724. In dollars, this would be $2.89.

Answer:

Step-by-step explanation:

a((100+50)/100)(100-50)/100

a(1.5)(.5)=0.75a

So a is larger than a(1.5)(0.5)

How much larger is a than 3a/4?

a/(3a/4)

a(4/3a)

a is 4/3 greater, so it does indicate a 33(1/3)% increase. Maybe they just want the fraction saying it is 1/3 greater or the difference of 0.25a

the two planes will be at the same altitude of approximately 5675.48 feet after 49.45 seconds.

A plane is a flat two-dimensional surface that extends infinitely in all directions. In geometry, a plane is defined as a surface that is completely flat and has no thickness. It is often represented as a coordinate system with two perpendicular axes, usually labeled as the x-axis and y-axis.

Assuming that the two planes maintain their rates of ascent, we can use the following equations to determine when the planes will be at the same altitude:

altitude of plane A = 4000 + 33.5t

altitude of plane B = 3146 + 50.75t

where t represents time in seconds.

To find the time at which the two planes will be at the same altitude, we can set the two equations equal to each other and solve for t:

4000 + 33.5t = 3146 + 50.75tSubtracting 3146 from both sides, we get:

854 + 33.5t = 50.75t

Subtracting 33.5t from both sides, we get:

854 = 17.25t

Dividing both sides by 17.25, we get:

t = 49.45 seconds

Therefore, it will take approximately 49.45 seconds for the two planes to be at the same altitude. To find the altitude at which they will meet, we can substitute this value of t into either equation. Using the equation for plane A, we get:

altitude of plane A = 4000 + 33.5(49.45) = 5645.08 feet

Using the equation for plane B, we get:

altitude of plane B = 3146 + 50.75(49.45) = 5675.48 feet

\(area = \frac{1}{2} (p \times a)\)

\(perimeter = 5s\)

The ratio of the side lengths, yellow to green

We see yellow is 36 and green is 60, so we just put that slash mark in between as indicated in the directions, giving us

36/60. We can reduce this to it's simplistic form of 3/5

The ratio of the perimeters, yellow to green.

To find the perimeter, we multiply the side by 5

Yellow; 36x5= 180

Green; 60x5= 300

We put that ratio slash... 180/300. Reducing it comes out to 90/150 > 30/50 > 3/5 also...

And that's because the polygons are similar.

Since the polygons are similar... what would be the ratio for the areas...

Yep, 3/5

Last is to find the area of the green.

The yellow is 45 and the ratio is 3/5. We can write the equation as a ratio

\( \frac{45}{x} = \frac{3}{5} \)

Now if we cross multiply;

\((45)(5) = 3x > 3x = 225\)

Last but not least, divide by 3

\(x = 75\)

In this case, Simone calculates the volume of a cube with side length 2.3 cm. The length is w

2.3 cm.

  $26.15

Step-by-step explanation:

You want to know the profit from sales of 4 cups of hot chocolate for $0.75 each and 22 cups of hot chocolate for $1.50 each after spending $9.85 on supplies.

The revenue from the sale of hot chocolate is ...

  (4 cups)($0.75/cup) +(22 cups)($1.50/cup) = $3.00 +$33.00 = $36.00

Profit is the difference between revenue and cost. The cost for supplies was $9.85, so the profit is ...

  profit = revenue - cost

  profit = $36.00 -9.85 = $26.15

Harley and Dakaria made $26.15 in all.

The sketch for slope is attached below.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

The expression 48s represents the number of scarves (s) and its per unit  (48).

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Given that, Emiko makes shibori scarves and sells them for $48 each on a website for handmade goods.

Here, the expression 48s represents the total price of buying s scarves

We need to tell what 48s mean,

So,

48s here is the total cost for buying s scarves,

That mean, if we buy s scarves we will have to pay $48s

Similarly, if we will buy 4 scarves, we will pay = 48 × 4 = $192

For 10 scarves, we will pay = 48 × 10 = $480
