Solve the system by substitution.
x + 6y = -2
-x= 3y - 10

Answers

Answer 1

Answer:

x = 22, y = -4

Step-by-step explanation:

x + 6y = -2 --- Equation 1

-x = 3y - 10 --- Equation 2

Equation 2 ×(-1): x = -3y + 10 --- Equation 3

Substitute x = -3y + 10 into Equation 1:

x + 6y = -2

-3y + 10 + 6y = -2

3y + 10 = -2

3y = -2-10

    = -12

y = -12 ÷ 3

y = -4

Substitute y = -4 into Equation 3:

x = -3y + 10

x = -3(-4) + 10

  = 12 + 10

x = 22

we are to find: the probability that the number of U.S. adult who thinks that the government should help fight childhood obesity is:

(a) exactly two  (b) at least four

Answer:

P(X =2) = 0.3160

P(X  ≥ 4) = 0.1656

Step-by-step explanation:

From the given information:

The population proportion = 39/100 = 0.39

the sample size = 6

(a) The required probability that exactly two adults fight childhood obesity out of the six is:

[tex]P(X=2) = (^6_2) (0.39)^2 (1-0.39)^{6-2}[/tex]

[tex]P(X=2) = \dfrac{6!}{2!(6-2)!} (0.39)^2 (1-0.39)^{4}[/tex]

[tex]P(X=2) = 15 \times 0.1521 \times 0.1385[/tex]

P(X =2) = 0.3160

(b)

The probability that at least 4 adults did is:

P( X ≥ 4) = P(X = 4) + P(X = 5) + P(X = 6)

[tex]P( X \ge 4) =(^6_4) (0.39)^4 (1-0.39)^{6-4} + (^6_5) (0.39)^5 (1-0.39)^{6-5}+ (^6_6) (0.39)^6 (1-0.39)^{6-6}[/tex]

[tex]P( X \ge 4) =(\dfrac{6!}{4!(6-4)!}) (0.39)^4 (1-0.39)^{2} +(\dfrac{6!}{5!(6-5)!}) (0.39)^5 (1-0.39)^{1}+ (\dfrac{6!}{6!(6-6)!}) (0.39)^6 (1-0.39)^{0}[/tex]

P(X  ≥ 4) = 0.1291 + 0.0330 + 0.0035

P(X  ≥ 4) = 0.1656

Miley has a shoe shelf 33 inches wide. If each of her shoes is 2 3 4 inches wide, how many shoes can she fit on the shelf? Which statements are correct? Check all that apply. To solve this problem, divide 33 by StartFraction 11 Over 4 EndFraction. To solve this problem, multiply 33 by StartFraction 11 Over 4 EndFraction. Miley’s shoe shelf can fit 12 shoes. Miley’s shoe shelf can fit 90 shoes.

Answers

Answer:
number of his shoe that can fit = 12 shoes
Step-by-step explanation:
Miley shoes shelf is 33 inches wide and each of her shoes is 2 3/4 inches wide . Her shoe width is represented in whole number fraction , so let's convert it to improper fraction .
2 3/4 = (4 × 2) + 3 = 11
2 3/4 = 11/4
Each of his shoe is 11/4 inches wide.
Her shoe shelf whole width is 33 inches wide . To get how many of her shoes can fit into the shelf , the shelf width will be divided by her each shoe width.
Mathematically,
number of his shoe that can fit = 33 ÷ 11/ 4
number of his shoe that can fit = 33 × 4/11
number of his shoe that can fit = 3 × 4
number of his shoe that can fit = 12 shoes

Kia buys a shirt that costs $12.50 and some pairs of socks that are $2.50 each. She pays a total of $27.50 How many pairs of socks did Kia buy? Write your solution in a complete sentence.

Answers

Answer:

6

Step-by-step explanation:

Given that:

Cost of shirt = $12.50

Cost per socks = $2.50

Total amount paid = $27.50

How many pairs of socks was purchased =?

Let Number of socks purchased = x

Total amount paid = cost of shirt + (cost per socks * number of socks)

27.50 = 12.50 + (2.50 * x)

27.50 = 12.50 + 2.50x

27.50 - 12.50 = 2.50x

15 = 2.50x

x = 15 / 2.50

x = 6

Number of pairs purchased = 6

one third of a land is on maize, a fifth of the remainder is on potatoes and the rest which is 0.5 ha is on beans. how much of the land is on potatoes?

Answers

Answer: [tex]1250\ m^2[/tex]

Step-by-step explanation:

Let x= Total land.

Then for Maize = [tex]\dfrac{x}{3}[/tex]    

For Potatoes = [tex]\dfrac15(x-\dfrac {x}{3})=\dfrac15(\dfrac{2x}{3})=\dfrac{2}{15}x[/tex]

For beans = [tex]x- (\dfrac{x}{3}+\dfrac{2}{15}x)=0.5 \ ha[/tex]

[tex]\Rightarrow\ x- (\dfrac{5x+2x}{15})=0.5 \ ha\\\\\Rightarrow\ x- (\dfrac{7x}{15})=0.5 \ ha\\\\\Rightarrow\ \dfrac{15x-7x}{15}=0.5 \ ha\\\\\Rightarrow\ \dfrac{8x}{15}=0.5 \ ha\\\\\Rightarrow\ x=0.5\times\dfrac{15}{8} \ ha\\\\\Rightarrow\ x=0.9375 \ ha[/tex]

1 ha = 10000.00 m²

0.9375 ha = 9375 m²

Land for potatoes = [tex]\dfrac{2}{15}(9375) =1250\ m^2[/tex]

Hence, [tex]1250\ m^2[/tex] of the land is on potatoes.

Find the x-intercept and y-intercept of the line. -3x+6y=11

Answers

Answer:

x- intercept is at [tex]( - 3 \frac{2}{3} ,0)[/tex].

y- intercept is at [tex](0,1 \frac{5}{6} )[/tex].

Step-by-step explanation:

The x-intercept occurs when y=0.

Thus, substitute y= 0 into the equation to find the x- intercept.

-3x +6y= 11

When y= 0,

-3x +6(0)= 11

-3x= 11

x= 11 ÷ (-3)

[tex]x = - \frac{11}{3} \\ x = - 3 \frac{2}{3} [/tex]

The y-intercept occurs at x= 0.

When x= 0,

-3(0) +6y= 11

6y= 11

y= 11÷ 6

[tex]y = 1\frac{5}{6} [/tex]
