Find ,giving your answer correct to 3 significant fig where necessary a. 60%of 850

Answer:

change it into slope intercept form: y=3/2x-5

Step-by-step explanation:

the slope is 3/2

Answer:

m = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

This is the answer because:

1) Use the slope-intercept form: y = mx + b to find the slope

1. The slope intercept form is y = mx + b where m is the slop and b is the y-intercept.

2. Subtract 3x from both sides of the equation:

-2y = 10 - 3x

3. Divide each term by -2 and simplify:

[tex]y=\frac{3}{2} -5[/tex]

4. Using the slope-intercept form, the slope is [tex]\frac{3}{2}[/tex]

Therefore, the answer is [tex]\frac{3}{2}[/tex]

Hope this helps! :D

Answer:

-16x

Step-by-step explanation:

6+(-16)=-10. If they all have "x", just combine like terms.

Answer:

?=-16x

Step-by-step explanation:

6x+?=-10x

-6x     -6x

    ?=-16x

I hope this is right, I don't know how to get the exact value of ? but if the ?  was a number I would be able to solve for x.

Answer: 0.0386

Step-by-step explanation:

Given: The probability hat the frozen chickens contain enough salmonella bacteria to cause illness if improperly cooked : p= 0.30

Sample size : n = 12

Let x = Number of contaminated chickens

Here , two outcomes for any chicken (either contaminated or not) , so it follows binomial distribution.

Binomial probability formula:

[tex]P(X=x) = \ ^nC_x p^x(1-p)^{n-x}[/tex]

The probability that the consumer will have more than 6 contaminated chickens :-

[tex]P(X>6)=P(X=7)+P(X=8)+P(X=9)+P(X=10)+P(X=11)+P(X=12)\\\\=^{12}C_6(0.3)^6(0.7)^6+^{12}C_7(0.3)^7(0.7)^5+^{12}C_8(0.3)^8(0.7)^4+^{12}C_9(0.3)^9(0.7)^3+^{12}C_{10}(0.3)^{10}(0.7)^2+^{12}C_{11}(0.3)^{11}(0.7)^1+^{12}C_0(0.3)^{12}(0.7)^0[/tex]

[tex]=0.03860084306\approx0.0386[/tex]  (simplified)

Hence, the required probability = 0.0386

284 CHILDREN

Step-by-step explanation:

5C+10A=7100

A=2C

5C +10(2C)=7100

5C+20C=7100

25C=7100

C=284

A=2C

A=568

Answer:

23º = x

Step-by-step explanation:

One straight line is ALWAYS 180º

(called a linear pair)

So your equation is

157º + x = 180

subtract x on both sides

and you get

23º

That is a question about angles.

The first thing that we should to note is that a line do a straight angle. A straight angle is an 180° angle.

So, we can say that the sum of the angle a and the angle of 157° is equal to a straight angle. Let's make and solve a equation:

[tex]a + 157 = 180\\a = 180 - 57\\a = 23[/tex]

Therefore, the missing angle is 23°.

I hope I've helped. :D

Answer:

me either lol sorry :)

Step-by-step explanation:

Answer:

A and B

Step-by-step explanation:

Basically all you have to do is combine those equations. How do you do that? You add/subtract the equations from each other, OR use substitution. It's hard to explain I recommend searching it up.

However, in this equation this is not what they are asking for. Only ONE equation has a solution when combined/substituted. Some have false solutions such as 3=0, which is not true. Some have infinite solutions where every number works.

Solving A:

This works because it actually gives us the value of y and x instead of giving us an incorrect statement.

Solving B:

This works as well!

Solving C:

This has no solution. It doesn't work and it ends up with 0 = -6, which is not true.

Solving D:

This has more than 1 solution.

Solving E:

This does not work, it has no solutions. It ends up with 0 = -2.
