Answer:

x=107/2, y=-40. (107/2, -40).

Step-by-step explanation:

y=-31-9=-40

2x+3(-40)=-13

2x-120=-13

2x=-13+120

2x=107

x=107/2

Answer: Greater than 10 N

Step-by-step explanation:

Given

Gravity force on metal is 10 N

But the metal piece is rising i.e. there must be an upward force greater than 10 N

Suppose the force is F

So, we can write

[tex]\Rightarrow F>10\ N[/tex]

Any force greater than 10 N is sufficient for the metal to move upwards

The greater the amount of force faster will be the movement

Answer:

15.13

Step-by-step explanation:

To find diameter, divide circumference by pi or 3.14

I'm going to change the fraction to a decimal, so 47.5

47.5/3.14 = 15.1273885

Round to nearest hundredth gives you 15.13

A company makes muesli which contains nuts and sultanas.

They counted the number of nuts in 50 individual serving packets.

They drew a table.

Number     Midpoint   Number of            

of nuts         (x)           packets (f)              f.x  

4 - 6               5                3                      15

7-9                 8                9                          

10 - 12           11                 12                      

13 - 15            14                17                          

16 - 18            17                 9                    

                                     50                    

To Find :

complete the table

calculate and estimate for the mean

The estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

a) To complete the table, we need to find the values of "fx" (frequency multiplied by the midpoint) for each class interval. Here's the updated table:

Number of Nuts Number of Packets Midpoint (x) fx

4-6 5 5 5 * 3 = 15

7-9 8 8 8 * 9 = 72

10 - 12 11 11 11 * 12 = 132

13 - 15 14 14 14 * 17 = 238

16 - 18 17 17 17 * 9 = 153

Total 50  610

b) To calculate an estimate for the mean, we use the formula:

Mean = Sum of (fx) / Total Number of Packets

Mean = 610 / 50

Mean ≈ 12.2

Therefore, the estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

Answer:x≤5

Step-by-step explanation:

Answer:

Option C 7.

Step-by-step explanation:

First lets define this symbol ≤.  This symbol mean smaller than or equal to.  So lets put options 3, 5, and 7 into this equation.

3 - 2 ≤ 3  This is correct.

5 - 2 ≤ 3   This is correct.

7 - 2 ≤ 3   This is incorrect.

Answer:

x = 5

Step-by-step explanation:

using the Pythagorean theorem:

(x-1)² + (x-2)² = x²

x²-2x+1 + x²-4x+4 = x²

reduce:

2x²-6x+5 = x²

subtract x² from each side:

x²-6x+5 = 0

(x-1)(x-5) = 0

x=1 but because shorter leg would be 0, a triangle would be impossible.

Answer:

  (c)  (6x^4 – 4)(36x^8 + 24x^4 + 16)

Step-by-step explanation:

The correct factoring can be found by looking at the first exponent in the second set of parentheses.

The factorization of ...

  (a^3 -b^3)

is ...

  (a -b)(a^2 +ab +b^2)

__

Here, you have a=6x^4 and b=4, so the first term in the second parentheses is ...

  a^2 = (6x^4)^2 = 6^2·x^(4·2) = 36x^8 . . . . matches the 3rd choice

Answer:

$3333.33 approx

Step-by-step explanation:

Given data

Rate r= 1.7%

Final Amount A=$4500

Time = 18years

Principal P= ????

The expression for the compound interest is given bellow as

A=P(1+r)^t

4500= P(1+0.017)^18

4500= P(1.017)^18

4500= P*1.35

P= 4500/1.35

P= $3333.33

Hence the principal is $3333.33 approx

Answer:3313.74

Step-by-step explanation:

Answer:

(7, 3)

Step-by-step explanation:

Using the midpoint formula

M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}

X = ax1+bx2/a+b

X = -5(1)+3(11)/1+3

X = -5+33/4

X = 28/4

X = 7

Y = ay1+by2/a+b

Y = 1(12)+3(0)/1+3

Y = 12/4

Y = 3

Hence the coordinate of P is at (7, 3)

Answer:

y = 8x + 2

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here, m = slope of the line

b = y-intercept

Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

By this formula, slope of a line passing through (1, 10) and (0, 2) will be,

m = [tex]\frac{10-2}{1-0}[/tex]

m = 8

Equation of the line will be,

y = 8x + b

Since, this line passes through (0, 2),

2 = 8(0) + b

b = 2

Therefore, equation of the line will be,

y = 8x + 2

40 people came to the Center to hike

Step-by-step explanation:

30 people took classes

22 did bird watching

12 did both

to solve, take 12 and subtract it from each one:

⇒ 22 - 12 = 10

18 people only took classes

10 people only did bird watching

12 people did both

18 + 10 + 12 = 40
