Answer: 49+x≤  125, where  x = Amount she can spend more on props.

Now she can spend no more than $76 on props.

Step-by-step explanation:

Given: Lucy can spend no more than $125 on props for a school play.

I.e. Total money she can spend ≤ $ 125

She already purchased costume fabrics that cost $49.

Let x = Amount she can spend more on props.

Required inequality: 49+x≤  125

Subtract 49 from both sides, we get

x≤ 76

Hence, now she can spend no more than $76 on props.

Answer:

The graph shows a line of best fit because the points are plotted evenly above and below the line.

Step-by-step explanation:

The best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

We have a line of best fit shown in the picture.

As we know if the slope of the line is positive then the correlation will be positive.

From the line of best fit:

Because the points are evenly spaced above and below the line, the graph displays a line of best fit.

Thus, the best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

Answer:

24 movies

Step-by-step explanation:

48 is a constant. 2 and 4 are variables. So we write 48+2x=4x to show they are equal after some amount of movies. Isolate to get 4x-2x=48. Simplify to get 2x=48. Divide each side by 2 to get x=24. The answer is 24.

Answer:

5 times

Step-by-step explanation:

Given that,

The area of Canada is approximately 1×10⁷ square kilometers, and the area of Mexico is approximately 2×10⁶ square kilometers.

We need to find the area of Canada is approximately how many times the area of Mexico.

Dividing both areas as follows :

[tex]\dfrac{A_c}{A_m}=\dfrac{10^7}{2\times 10^6}\\\\\dfrac{A_c}{A_m}=5\\\\A_c=5A_m[/tex]

So, the area of Canada is approximately 5 times the area of Mexico.

Answer:he should build them 25x10

Step-by-step explanation:

Encik Ahmad can build 10 square plots with three different sizes.

Rectangle is a polygon in two dimensional geometry which has four sides and four angles and each angle being right angles.

Length of the rectangular plot = 85 m

Width of the rectangular plot = 30 m

We have to find the number of square plots Encik Ahmad can built of three different sizes.

For that first we take a 45 m length of the plot.

Divide it to three equal lengths. We get three lengths with each 15 m length.

Along the width also, divide into two equal width, each having a width of 15 m.

Each 15 m length, we will get two square plots.

Along 45 m length, we get 3 × 2 = 6 square plots.

The remaining rectangle has length 40 m and width 30 m.

Divide this length as 30 m and 10 m.

So we get a square of dimension 30 m.

Remaining is a rectangle whose remaining length is 10 m and width 30 m.

Along the width, divide into three equal widths, each 10 m.

So there we get three square plots with side length 10 m.

So we have 10 square plots, 6 having the side length 15m, 1 having the side length 30 m and 3 having the side length 10 m.

Hence he get 10 square plots having three different sizes as 15 m, 30 m and 10 m.

The answer is  ( D ),   y ≤ 6

The range begins from minimum value to maximum value.

However, in the graph. There's no minimum value as it's heading toward negative infinity.

So we use y ≤ 6 instead.

So the clear answer is y ≤ 6 or ( D )

Answer:

Step-by-step explanation:

Resolvemos usando la fórmula de puntuación z

z = (x-μ) / σ, donde

x es la puntuación bruta

μ es la media poblacional = 70 kg

σ es la desviación estándar de la población = 3 kg

a) Entre 60 y 75 kg

Para x= 60kg

z = 60 - 70/3 kg

=-3.33333

Valor de probabilidad de la tabla Z:

P(x = 60) = 0.00042906

Para x = 75 kg

z = 75 - 70/3 kg

= 1.66667

Valor de probabilidad de la tabla Z:

P(x = 75) = 0.95221

P(x = 75) - P(60)

0.95221 - 0.00042906

b) Más de 90 kg

Para x> 90 kg

z = 90 - 70/3

= 6.66667

Valor de probabilidad de la tabla Z:

P (x <90) = 1

P (x> 90) = 1 - P (x <90) = 0

Número de árboles = 500

Por tanto, 500 × 0 = 0 árboles

c) Menos de 64 kg

x <64 kg

z = 64 - 70/3 kg

= -2

Valor de probabilidad de Z-Table:

P (x <64) = 0,02275

Hay 500 arboles

= 500 × 0.02275

= 11.375 árboles

D) 64 kilogramos

x = 64 kg

z = 64 - 70/3 kg

= -2

Valor de probabilidad de Z-Table:

P (x = 64) = 0,02275

Hay 500 arboles

= 500 × 0.02275

= 11.375 árboles

Answer:

step 2

Step-by-step explanation:

Answer: Amount borrowed at 9% = 9,428.57

Amount borrowed at 7% = $18,857.14

Amount borrowed at 10% = $ 21,714.29

Step-by-step explanation:

Formula for simple interest :

I = PRT,

P= Principal, R =rate , T= time

Let x = amount borrowed at 9%.

y = amount borrowed at 7%.

z = amount borrowed at 10%.

i.e. x+y+z= 50000    (i) [Given : amount invested = 50000]

Interest on x = x (0.09)(1)   [as P=x,  T=1 year, r= 0.09]

= 0.09x

Similarly

Interest on y = y(0.07)(1) = 0.07y

Interest on z = z(0.1)(1)=0.1z

Total interest = 0.09x+0.07y+0.1z = 4340   (ii)

Also, y=2x   [given]  (iii)

Put y=2x in (i) and (ii), we get

x+2x+z= 50000 ⇒ 3x+z=50000    (iv)

0.09x+0.07(2x)+0.1z=4340  ⇒ 0.09x+0.14x+0.1z=4340

⇒ 0.23x+0.1z=4340    (v)

Multiply 10 on both sides of (v)

2.3x+z=43400   (vi)

Eliminate (vi) from (v)

0.7x=6600

⇒ x= 9,428.57

From (iii), y= 2(9428.57) =18,857.14

From (vi),

2.3(9428.57)+z=43400

⇒ 21685.71+z=43400

⇒ z= 43400-21685.71

⇒ z=21714.29

Hence, Amount borrowed at 9% = 9,428.57

Amount borrowed at 7% = $18,857.14

Amount borrowed at 10% = $ 21,714.29
