Sophia wrote 260,880 as (2 times 100,000)+(6 times 10,000)+(8 times 100). What error did Sophia make
Romashka [77]

260,880 as (2 times 100,000)+(6 times 10,000)+(8 times 100).

here Sophia must consider 80 as 8 times 10

so that complete expression becomes

260,880 = (2 times 100,000)+(6 times 10,000)+(8 times 100)+(8 times 10)

A newspaper article states that 90% of drivers in Iowa wear their seatbelt. Suppose we are interested in estimating the proporti
konstantin123 [22]

Answer:

The sample size is  n  = 3457

Step-by-step explanation:

From the we are told that

  The population proportion is  p =  0.90

  The margin of error is  E =  0.01  

From the question we are told the confidence level is  95% , hence the level of significance is    

      \alpha = (100 - 95 ) \%

=>   \alpha = 0.05

Generally the sample size is mathematically represented as

       n  =[  \frac{ Z_{\frac{\alpha }{2} }  }{E} ]^2 * p(1-p)

=>  n  =[  \frac{ 1.96  }{0.01} ]^2 * 0.90(1-0.90)

=>   n  = 3457

Solve with steps<br> 5^(x+3)=25^(x-2)
Taya2010 [7]

5^(x+3)=25^(x-2)

Apply the exponent rule ( 5 ^2 = 25, so remove the 5 and replace 25?with 2)


x + 3 = 2(x-2)

Simplify:

X + 3 = 2x -4

Add 4 to both sides:

X + 7 = 2x

Subtract x from both sides

X = 7


Answer: x = 7

1.) 75 x .62 = 46.5 I multiplied by .62 because the kph to mph ratio is 1:.62
2.) 20 x 1.6 = 32 I multiplied by 1.6 because that's how many km are in a mile.
