HELP PLEASE HELP!!!!

Answer:

Y = -2,  X = 4

Step-by-step explanation:

When you first use the elimination method, you would multiply 2x-y = 10 by -2 so that you could get the 4x to be eliminated.

4x-3y = 22

(2x-y = 10)-2 = -4x + 2y = -20

When you add those 2 together you are left with -y = 2, which you divide by negative to get y = -2. Then you substitute -2 for y to solve for x. I substituted the bottom equation

2x - (-2) = 10

2x +2 = 10

2x = 8

Divide both sides by 2 to get x = 4.

Answer:

Average velocity = 1

Step-by-step explanation:

f(3) = 3² - 3(3) + 4 = 4

f(1) = 1² - 3(1) + 4 = 2

[tex]Velocity = \frac{f(3) - f(1)}{3-1} =\frac{4-2}{3-1} =\frac{2}{2} =1[/tex]

Answer:

D

Step-by-step explanation:

Range is all the possible Y values in a graph

we can see that the graph will never reach a y value greater than three but will go to negative infinity

This means that answer is D (the y value will always be less than or equal to 3)

Answer:

2 and -1/2 since -1/2 is negative the answer is 2

Step-by-step explanation:

I plugged the values into the quadratic formula

Answer:

The answer is below

Step-by-step explanation:

The question is not complete. A complete question is in the form:

A letter is chosen at random from the letters of the word EXCELLENT. Find the probability that letter chosen is i) a vowel ii) a consonant.

Solution:

The total number of letters found in the word EXCELLENT = 9

i) The number of vowel letters found in the word EXCELLENT = {E, E, E} = 3

Hence, probability that letter chosen is a vowel = number of vowels / total number of letters = 3 / 9 = 1 / 3

probability that letter chosen is a vowel = 1/3 = 0.333 = 33.3%

ii) The number of consonant letters found in the word EXCELLENT = {X, C, L, L, N, T} = 6

Hence, probability that letter chosen is a consonant = number of consonant / total number of letters = 6 / 9 = 2 / 3

probability that letter chosen is a consonant = 2/3 = 0.667 = 66.7%

Answer:

  ? = √87 ≈ 9.33

Step-by-step explanation:

The square of the hypotenuse (h) of the small triangle is the sum of the squares of its legs.

  h^2 = 5^2 + 12^2 = 25 +144 = 169

The square of the hypotenuse of the large triangle is also the sum of the squares of its legs.

  h^2 +?^2 = 16^2

  169 +?^2 = 256

  ?^2 = 256 -169 = 87

Taking the square root, we find the missing leg length to be ...

  ? = √87 ≈ 9.33

Answer:

Number of trout caught by Bill = 16 trout

Number of trout caught by Steve = 30 trout

Step-by-step explanation:

Given:

Total number of trout caught = 46

Number of trout caught by Steve = Number of trout caught by Bill + 14

Find:

Number of trout caught by Steve

Number of trout caught by Bill

Computation:

Assume;

Number of trout caught by Bill = a

Number of trout caught by Steve = a + 14

So,

Number of trout caught by Steve + Number of trout caught by Bill = Total number of trout caught

a + a + 14 = 46

2a = 46 - 14

2a = 32

a = 16

Number of trout caught by Bill = 16 trout

Number of trout caught by Steve = a + 14

Number of trout caught by Steve = 16 + 14

Number of trout caught by Steve = 30 trout

Step-by-step explanation:

g+g is like 1+1. You add them together to get 2. Instead of 2, it is g so the answer is 2g.

Answer:

Part A

The null hypothesis H₀; The injuries and illnesses have no relationship in the weekend

The alternative hypothesis Hₐ; The injuries and illnesses occur with equal frequency on the weekend

Part B

P-value from;

Tables, 0.1 < P([tex]\chi^2[/tex] < 4.12) < 0.9

Chi-square calculator, P([tex]\chi^2[/tex] < 4.12) = 0.87

Step-by-step explanation:

The given data is presented as follows;

[tex]\begin{array}{ccc}Day&&Number\\Fri&&21\\Sat&&19\\Sun&&10\end{array}[/tex]

The significance level, α = 0.05

Part A

The hypothesis is to test that the given injuries and illnesses occur with equal frequency of the weekend

The null hypothesis H₀; The injuries and illnesses have no relationship in the weekend

The alternative hypothesis Hₐ; The injuries and illnesses occur with equal frequency on the weekend

Let the expected frequency, each day of the weekend = (21 + 19 + 10)/3 = 50/3 = 16.[tex]\overline 6[/tex]

We get;

[tex]\begin{array}{ccc}Day & Observed \ Number& Expected \ Number \\Fri&21& 16.\overline 6\\Sat&19&16.\overline 6\\Sun&10&16.\overline 6\end{array}[/tex]

The chi-square test statistics

[tex]\chi^2[/tex] = (21 - 50/3)²/(50/3) + (19 - 50/3)²/(50/3) + (10 - 50/3)²/(50/3) = 4.12

The [tex]\chi^2_u[/tex] with (3 - 1) = 2 degrees of freedom = 5.991

The decision rule, [tex]\chi^2[/tex] > 5.991, we reject the null hypothesis

Given that we have [tex]\chi^2[/tex] = 4.12 < 5.991, we fail to reject H₀, therefore, there is not enough statistical evidence to suggest that the meal plan are related at α = 0.05

Part B

From the chi-square table, we have the p-value at 2  degrees of freedom for the test statistic of 4.12 is between 0.9 and 0.1

Using the chi-square calculator, we have;

P([tex]\chi^2[/tex] < 4.12) = 0.87.

Answer:

-1/2x+1=x-5

x=4

y=-4/2+1

y=-2+1

y=-1

(x,y)=(4,-1)

Answer:

12

Step-by-step explanation:

We can try and get both sides to have a common denominator. If we multiply the left side by 4, we get 12/16=x/16. Here, it is clear that x=12.

Answer:

x is equal to 12/16

Step-by-step explanation:

If you divide 12/16 by 4 you will realize that it is equal to 3/4. Therefore x is equal to 12. That is a really explanation, but hope it helps!

Answer:

24 cm²

Step-by-step explanation:

Given :-

And we need to find the area of the figure. We can find the area of ||gm as ,

[tex]:\implies[/tex] Area = base * height

[tex]:\implies[/tex] Area = 6cm * 4cm

[tex]:\implies[/tex] Area = 24 cm²

Hence the area of the ||gm is 24cm² .

Answer:

44u-36

Step-by-step explanation:

Apply the distributive property.

−6(−7u)−6⋅6+2u

Multiply −7 by −6.

42u−6⋅6+2u

Multiply −6 by 6.

42u−36+2u

Add 42u and 2u.

44u-36

Answer:

The Correct option is 36.60

Step-by-step explanation:

The key to solving this question lies around measurement conversion,specifically converting grams into its equivalence in kilograms.

1000 grams equal one kilogram

9 grams=9/1000 kg

9 grams=0.009 kg

70 grams=70/1000 kg

70 grams=0.07 kg

Julie pays=$600*0.009=$5.4

Jacques pays=$600*0.07=$42

Jacques pays   $36.60 more ($42-$5.4) than Julie paid

Option is wrong because that was what Julie paid

Option D is wrong because that was what Jacques paid

Option B is obviously wrong
