13.48x - 200 < 256.12

podryga [215]

Answer:

x < 33.84

Step-by-step explanation:

we have

13.48x-200 < 256.12

Solve for x

Adds 200 both sides

13.48x-200 +200 < 256.12+200

13.48x < 456.12

Divide by 13.48 both sides

13.48x/13.48 < 456.12/13.48

x < 33.84

The solution is the interval ----> (-∞, 33.84)

All real numbers less than 33.84

Plz help with any of them it’s a emergency

devlian [24]

To find a perimeter, add all sides together:

9) 12 + 12 + 8 + 8 = 20 + 20 = 40 in
10) 3 + 3 + 3 + 3 = 6 + 6 = 12 cm

To find area, multiply length and width, or base and height:

11) 3 x 6 = 18
12) 10 x 30 = 300 ft
13) 12 x 12 = 144 cm
14) 7 x 4 = 28 m

15)
Perimeter: 2(2) + 2(16) = 4 + 32 = 36
Area: 1 x 16 = 16

hope this helps

Testing to see if there is evidence that the proportion of US citizens who can name the capital city of Canada is greater than 0

klemol [59]

Answer:

b) B and D and c) A and C

Step-by-step explanation:

The hypotheses would be:

$H_0: p =0.75\\H_a: p >0.75$

(Right tailed test at 5% level)

Sample proportions are

Sample A B C D

Success 31 34 27 38

Proportion p 0.775 0.85 0.675 0.95

Std error

(sqrtpq/n) 0.066 0.056 0.074 0.034

p diff

p-0.75 0.025 0.10 - 0.075 0.20

Z stat

p diff/SE 0.0757 1.77 1.01 5.80

p value 0.469 0.038 0.156 0.000001

we find that p value is more smaller than alpha, the more accurate the alternate hypothesis.

b) Only B and D provide against the null. Because p <0.05

c) A and C provide no evidence for the alternative because p >0.05
