What’s the answer in simplified form

Mathematics
1 answer:
Schach [20]2 years ago
3 0

Answer:

Step-by-step explanation:

To solve this correctly, you need to make sure to distribute the negative onto both terms in the second parentheses.

So fully expanded, the problem would be:

2y² + 8y -7 + 3y - 3 = ?

You can easily rearrange the terms, or just do it in your head!

It would become:

2y² + 8y +3y -7 -3

= 2y² + 11y -10

Make sure you keep the terms with different variables separate! I hope this is helpful!

insurance company checks police records on 559 accidents selected at random and notes that teenagers were at the wheel in 91 of
ss7ja [257]

Answer: (13.22\%,\ 19.34\%)

Step-by-step explanation:

Given : Sample space : n= 559

Sample proportion : \hat{p}=\dfrac{91}{559}=0.162790697674\approx0.1628

=16.28\%

Significance level : \alpha= 1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

Confidence level for population proportion:-

\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.1628\pm (1.96)\sqrt{\dfrac{0.1628(1-0.1628)}{559}}\\\\=0.1628\pm0.030604971367\\\\\approx 0.1628\pm0.0306=(0.1322,\ 0.1934)=(13.22\%,\ 19.34\%)

Hence, 95% confidence interval for the percentage of all auto accidents that involve teenage drivers.= (13.22\%,\ 19.34\%)
