(2.02 -16.61 : 5.5 ) : 2.5 - 1.6 =
solve this pls ​

Answer:

Yes, your simultaneous equations are correct;

Solve them like so:

170 + 1.6449σ = 180 - 0.8416

2.4865σ = 10

σ = 4.0217...

μ = 170 + 1.6449(4.0217...)

μ = 176.615...

MS is correct, you must've made an error in solving or rearranging

Answer:

23 & 13

Step-by-step explanation:

23+13=36

Answer:

x = 23

y = 13

Step-by-step explanation:

Let the number be x and y.

As given,

x + y = 36 ---(i)

x - y = 10 ---(ii)

Adding eq(i) and eq(ii) we get,

2x = 46

x = 23

Now putting the value of x in eq(ii)

23 - y = 10

y = 13

So the two numbers are 23 and 13.

Answer:

Olivia's puppy is linear i know this because after applying to the graph i got a straight line.

Step-by-step explanation:

Answer:

When looking at the table you can see that for every increase of 1 in the x value it results in an increase of 1 in the y value. The rate of change is constant.

Rate of change is calculated by the change in y/change in x

For the points (1,2), (3,3) and (5,4) the rate of change calculation would be as follows:

(1, 2)(3, 3)

3-2 / 3-1= 1/2

(3, 3)(5, 4)

4-3 / 5-3= 1/2

Since both equal 1/2 the rate of change is constant therefore making it linear.

Answer:

-4.3

Step-by-step explanation:

a+(-1.2)= -5.5

a-1.2=-5.5

add 1.2 to both sides

a-1.2+1.2= - 5.5+1.2

simplify

a= - 4.3

Answer:

a=-4.3

Why?:

You would have to keep the answer negative, this is because if it were to be positive it would make the negative decrease.

You could easily get a line paper and line up-

-4.3

+ -1.2

_______

-5.5

-5.5-(-1.2) would make the equation end up like -5.5+1.2, and -5.5+1.2=-4.3

Therefore,

a=-4.3

Step-by-step explanation:

Answer:

D: (-6,0)

Step-by-step explanation:

Set f(x) equal to 0 and solve for the values of x:

f(x) = (x+6)(x-3)

0 = (x+6)(x-3)

x+6=0 and x-3=0

x=-6 and x=3

Therefore, the x-intercepts are (-6,0) and (3,0). Because only (-6,0) is an option, then option D is correct.

Answer: (-6, 0)

Step-by-step explanation:

got it right on my test

Step-by-step explanation:

Given,

a/b = c/d = 2/5

=> a + 3c + 4/b + 3d + 10

=> (a/b) + (3c/3d) + (4/10)

=> 2/5 + 3(c/d) + 4/10

=> 2/5 + 3(2/5) + 4/10

=> 2/5 + 6/5 + 2/5

=> 2 + 6 + 2/5

=> 10/5

=> 2

Answer:

The solution would be C. (2, -4)

Step-by-step explanation:  Equation: 2y = -3x - 2

1. (2, -3)

  2(-3) = -3(2) - 2

  -6 = -6 - 2

  -6 = -8   (Not a solution)

2. (-3, 2)

   2(2) = -3(-3) - 2

   4 = 9 - 2

   4 = 7   (Not a solution)

3. (2, -4)

   2(-4) = -3(2) - 2

   -8 = -6 - 2

   -8 = -8   (Solution)

4. (-4, 2)

   2(2) = -4(-4) - 2

   4 = 12 - 2

   4 = 10   (Not a solution)

Answer:

C

Step-by-step explanation:

The probability of getting heads or tails is 50%.

300*50% = 150

Answer:

C. 150 times

Step-by-step explanation:

Because a coin only has tails and heads, you can say that the probability would be half. Because it was tossed 300 times, you can say: 300*0.5=150

20x=400-100

20x=300

x= 300/20
