Plz help if correct ill give brailiest also the first answer was x<1

Answers

I think it is A it has to be x<1 but i am not totally sure

Answer:

For x<1, answer would be A.

Step-by-step explanation:

Since the less than sign doesn't have a line under it "making it less than or equal to" the dot on the graph is not shaded, and if you simply read the inequality, x is less than 1, so it goes in the direction less than 1.

From a random sample of 185 children from school G, 108 indicated they wanted to study science in college. From a different random sample of 165 children from school H, 92 indicated they wanted to study science in college.

Underroot(108/185)(1 − 108/185)185 − (92/165)(1−92/165)/165.C. Underroot(108/185)(1 − 108/185)185 + (92/165)(1−92/165)165.D 1.96 underroot(108/185)(1 − 108/185)185 + (92/165)(1 − 92/165)165.E. Underroot(200/300)(1 - 200/300)/350.

Answers

Answer:

C. Underroot(108/185)(1 − 108/185)185 + (92/165)(1−92/165)165.

Step-by-step explanation:

Sample size, n1 = 185

x1, = 108

P1 = x1 / n1 = 108 / 185 =

Sample size, n2 = 165

x2, = 92

P2 = x2 / n2 = 92/165

Standard Error = sqrt[(p1(1-p1))/n1 + (p2(1-p2))/n2]

sqrt[(108/185(1 - 108/185)) /185 + (92/165(1 - 92/165)) / 165]

C. Find the equation that is parallel to y = 12x-2 and crosses the point (6,2)

Answers

Answer:

The equation of line a is y=(1/2)x−1, and it passes through point (6,2).

       line b is: y = -2x + c and we use point (-6,2) to find b.

      2 = -2(-6) + c

     14 = c

The equation for line b is: y = -2x + 14

The y-intercept (which is the point where x=0) is the point (0,14.)        So, y=14

$45.00 iPod shuffle 1GB

What will the sale price be if you purchase this item?

Answers

Answer:

$44.55

Step-by-step explanation:

10% of 45 is 4.5

45 * 0.1 = 4.5

So subtract 4.5 from 45

45 - 4.5 = 40.5

Now get 10% of 40.5

40.5 * 0.1 = 4.05

Add 4.05 to 40.5

4.05 + 40.5 = 44.55

is 1 equivalent to -13 - (-12)

Find the height of this cone using the Pythagorean Theorem. 9 in. h = [?] in. 6 in. a C Pythagorean Theorem: a2 + b2 = c2 b​

Answers

Answer:

h = √72 in.

Step-by-step explanation:

Height of the cone using pythagorean theorem, a² + b² = c², where:

a = h

b = ½(6) = 3 in.

c = 9 in.

Plug in the values

h² + 3² = 9²

h² + 9 = 81

h² + 9 - 9 = 81 - 9

h² = 72

h = √72
