Find the value of x to make the following expression true. 5º = 3,125​

Answer:

280 adult tickets

130 student tickets

190 children tickets

were sold at the concert

Step-by-step explanation:

Let the number of students be s , adults a and children c

Total 600;

Thus;

a + s + c = 600 •••••••(i)

let us look at revenue

Revenue = number * ticket price

For adults; a * 7 = $7a

For students ; s * $3 = $3s

For children; c * $2 = $2c

Total is 3150

thus;

7a + 3s + 2c = 3150 ••••••••(ii)

150 more adults than students;

a = s + 150 ••••••(iii)

Substitute iii into ii and i

into ii

7(s + 150) + 3s + 2c = 3150

7s + 1050 + 3s + 2c = 3150

9c + 3s = 3150-1050

9c + 3s = 2,100 •••••••(x)

Substitute into i

a + s + c = 600

s + 150 + s + c = 600

2s + c = 600 - 150

2s + c = 450

c = 450 - 2s ••••••(xx)

Now substitute xx into x

9(450-2s) + 3s = 2100

= 4050-18s + 3s = 2100

4050-2100 = 18s - 3s

15s = 1950

s = 1950/15

s = 130

c = 450 -2s

c = 450 - 2(130)

c = 450 - 260

c = 190

a = 150 + s

a = 150 + 130

a = 280

Answer:

The size of your sample is 75.

Step-by-step explanation:

The sample collected is as follows:

Flower               Customers

 Lily                         10  

Daffodil                   23

Rose                      28  

Daisy                      14

A sample denotes a smaller, controllable form of a larger cluster. It is a subset comprising of the characteristics of a bigger population. Samples are used in statistical experiments when the population under consideration is too large for the test to include all the members.

The sample size in this case =  10 + 23 + 28 + 14 = 75

Thus, the size of your sample is 75.

Answer:

8 signs

-9 - 5        -14

———  =   ——

5 - (-3)        8

Step-by-step explanation:

The equation to find a slope is y2 - y1 over x2 - x1, so the equation would be -9 - 5 over 5 - negative 3.

(btw -14 / 8 is -1.75 so the answer is -1.75)

1. Convert to improper fraction:

2. Change sign and find reciprocal of second number

3. Multiply

4. Simplify

Answer:

D

Step-by-step explanation:

we're given the three zeros of a cubic polynomial

[tex]f(x) = (x-1)(x+2)(x-2)\\f(x) = (x-1)(x^2-4)\\f(x) = x(x^2) - 4x - x^2 + 4\\f(x) = x^3 - x^2 - 4x + 4[/tex]

The expression (3)(4)(-3/4) is equivalent to -9.

None of the given options is correct.

Given information:

The expression is (3) (4) (-3/4).

Multiplying 3, 4, and -3/4, we get:

(3)(4)(-3/4),

Simplify the parenthesis,

= 12(-3/4)

Multiplying,

= -36/4

Divide -36 by 4, and we get,

= -9

Therefore, the expression is equivalent to:-9

Answer:

An isosceles triangle

Step-by-step explanation:

An isosceles triangle has 2 of the same sides and angles.

Plz give me brainliest.

The given triangle with two angels is 70° and will be the isosceles triangle.

A summation, also abbreviated as a sum, is the consequence of adding two or more numbers or quantities. Usually are always an equivalent number of terms in a summation.

There could be only two terms, and there could be one hundred, thousand. There seem to be summations with an infinite number of representatives.

On another hand, an isosceles triangle is a triangle in which any two sides or angles will be the same.

Hence given that the triangle has

Angle first = 70°

Angle second = 70° since there are two angles same so there will also be two sides equal so it will be an isosceles triangle.

Answer:

h<0

Step-by-step explanation:

27h-61h>61h-61h

-34h>0

-34h/-34h>0/-34h

H<0

4. H(17)+H(27)=h(29)

H•17 +h(21)=h(29)

17h+h(21)=h(29)

H17 +h•(21)=h(29)

17h+h(21)=h(29)

combine it

17h+21h=h(29)

38=h(29)

38h=h•29

38h=h29

38h-29h=h29-29h

9H=0

divide both side

9h/9 =0/9

H=0/9 or H=0

Answer:

a.) 0.468

b.) -0.075

c.) 0

Step-by-step explanation:

Given the distribution :

Z~N(μ = 0,σ = 1)

Distribution = normal

Mean (μ) = 0

Standard deviation (σ) = 1

a) Find x so that P(Z ≤ x) = 68%

Using the z probability calculator : Zscore corresponding to 68% = 0.68 = 0.468

Usingbthe relation :

Zscore = (x - m) / σ

0.468 = (x - 0) / 1

0.468 = x - 0

x = 0.468

b) Find the data value x at the 47th percentile

47th percentile = Zscore of - 0.075

Zscore = (x - m) / σ

-0.075 = (x - 0) / 1

-0.075 = x - 0

x = -0.075

c) Find the data value x at the 50th percentile

50th percentile = Zscore of 0.0

Zscore = (x - m) / σ

0.0 = (x - 0) / 1

0.0 = x - 0

x = 0

• x+y = 4

• 2x+3y= 6.

• x and y.

• x+ y = 4

=> x = 4 - y

put x in :

• 2x + 3y = 6

=> 2 (4-y)+3y = 6

=> 8 - 2y +3y = 6

=> y = 6 - 8

=> y = -2 .

Now, put y in x+y= 4.

=> x+(-2)= 4

=> x - 2 = 4

=> x = 4+2

=> x= 6.

Hence, the value of x is 6 and y is -2.

I hope it will help you.

Answer:

7 min : 24 min

Step-by-step explanation:

Convert 2 hours into minutes (it's easier when the units are the same)

35 min : 120 min

Both have a high common factor of 5

Divide both sides by 5

35/5 : 120/5

7 min : 24 min

Answer:

m = 2/5

Step-by-step explanation:

If you look carefully you see that each new y value is obtained by adding 2/5 to the previous one.  That 4/5 came from adding 2/5 to 2/5.

If we move from x = 0 to x = 1, y increases from 6/5 to 8/5.

Thus:  the "run" is 1; the "rise" is 2/5.

Thus, the slope is m = rise / run = 2/5 divided by 1, or just m = 2/5

It is given that,

Jonathan wants to buy his whole basketball team new clothes.

On Amazon there is a sell for 11 shirts for $145.23

The cost of 1 shirt on amazon:

[tex]C=\dfrac{145.23}{11}=\$13.20[/tex]

On Walmart sell for 23 shirts for $212.19.

The cost of 1 shirt on Walmart:

[tex]C=\dfrac{212.19}{23}=\$9.225[/tex]

Cost of 1 shirt on Amazon is $13.20 and on Walmart is $9.225. It is clear that on Walmart it is better to buy for $9.225.
