Answer:

6. D.

7. F.

8. A.

9. B.

10. C.

Step-by-step explanation:

6. 9 + (12 - 10)

12 - 10 = 2

9 + 2 = 11

7. (20 - 15) x 2

20 - 15 = 5

5 x 2 = 10

8. 10 ÷ 5 + 7

10 ÷ 5 = 2

2 + 7 = 9

9. 6 + 2 x 3

2 x 3 = 6

6 + 6 = 12

10. (2 x 4) + 8

2 x 4 = 8

8 + 8 = 16

Let me know if this helps!

Help me solve this question for geometry and thanks !!

Degger [83]

Answer:

(-2, -6)

Step-by-step explanation:

g(x) = (x+2)²-6

= x²+4x+4-6

= x²+4x-3

the vertex :

x = -4/2 = -2

y = (-2+2)²-6 =0-6 = -6

point of vertex : (-2, -6)

Svet_ta [14]

Answer:

Required equation is y - 36 = (24 - 36)/(2 - 1) (x - 1)

y - 36 = -12(x - 1)

y - 36 = -12x + 12

12x + y = 12 + 36

12x + y = 48

A study found that a 95% confidence interval for the mean μ of a particular population was computed from a random sample of 1200

kotykmax [81]

Answer:

95% confidence interval for the mean μ is (6,14)

The Population mean μ lies between ( 6, 14 )

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given random sample 'n' = 1200

95% confidence interval for the mean μ is determined by

$(x^{-} -Z_{\alpha } \frac{S.D}{\sqrt{n} } , x^{-} +Z_{\alpha } \frac{S.D}{\sqrt{n} } )$

Level of significance = 95% 0r 0.05

Z₀.₀₅ = 1.96

$(x^{-} -Z_{\alpha } \frac{S.D}{\sqrt{n} } , x^{-} +Z_{\alpha } \frac{S.D}{\sqrt{n} } )$ = 10 ± 4

Mean of the small sample = 10

95% of confidence intervals are

( 10 ±4 )

( 10 -4 , 10+4)

( 6 , 14 )

95% confidence interval for the mean μ lies between ( 6, 14 )
