What is 39.79949748 rounded to the nearest hundredth?

Rufina [12.5K]

Answer:

$Number = 39.80$

Step-by-step explanation:

Given

$Number = 39.79949748$

Required

Approximate (to the nearest 100th)

This means that, we approximate at the second digit after the decimal.

So:

i.e,

Number = 39.79 [Begin approximation] 949748

The first digit after [Begin approximation] is then approximated using the following rule:

$0 - 4 \approx 0$

$5 - 9 \approx 1\\$

Since 9 falls in $5 - 9 \approx 1\\$ category, the number becomes:

$Number = 39.[79+1]$

$Number = 39.80$

Researchers collected data from 100 randomly chosen counties in Texas on pollution levels and asthma rates. Pollution levels wer

lesya692 [45]

Answer:

The answer is "3.14".

Step-by-step explanation:

The coefficient of pollution level is "b" and "a" intercept

$\to y=a+bx\\\\$

We must verify it.

$H_0 :\beta = 0\\\\H_a : \beta \neq 0\\\\$

$Beta \to b=1.76, SE=0.56 \ Estimate$

The statistics on tets are now provided

$\to t=\frac{b}{SE}=\frac{1.76}{0.56}=3.14$

Because statistics will be more than critical $(1.984)$ values, we thus reject $H_0$
