-7.
5x-3 = -15
-15-4\4= -16
-16 + 9 = -7

Using with PEMDAS: First, using with parentheses, you do 6-2= 4. Now the problem should be 9+5×(-3)-4÷4. Then, exponents, but in this problem, there are no exponents so we can skip that. Now, M (Multiplying), if you see a multiplication problem, just do it. 5×(-3)= -15. If the two signs are the same, then the answer will be a positive. But the two factors are different so they have to be negative. 9+(-15)-4÷4, should be the problem. Now, D (Division), you get 4÷4= 1. The problem should be 9+(-15)-1. This should be A, or Addition. 9+(-15)= -6. So, (-6)-1. The last one is subtraction so get (-6)-1 equals -5. The answer should be a -5.

(Remember, if you see several multiplication problems, do it from left to right. This goes for all of the PEMDAS strategy.)

Answer:

As=0.13

Step-by-step explanation:

If we have central angle we use this rule to find area of sector :

$As=\pi r^{2}(\frac{C}{360})$

C is central angle. r is radius.

$As=\pi *9*\frac{\frac{9\pi }{17} }{360} =\\\\As=\pi *9*\frac{9\pi }{17*360} =\\\\$

Evaluate :

$\frac{798.63}{6120}=0.13$

A nutrition laboratory tested 25 "reduced sodium" hotdogs of a certain brand, finding that the mean sodium content is 310 mg wit

Answer:

The 95% confidence interval is $295.9 < \mu< 324.1$

A 95% level of confidence mean that there is 95% chance that the true population mean will be in this interval

Step-by-step explanation:

From the question we are told that

The sample size is $n = 25$

The mean is $\= x = 310 \ mg$

The standard deviation is $\sigma = 36 \ mg$

Given that the confidence level is 95% then the level of significance is mathematically represented as

$\alpha = 100 - 95$

=> $\alpha = 5\%$

=> $\alpha = 0.05$

Next we obtain the critical value of $\frac{\alpha }{2}$ from the normal distribution table , the value is

$Z_{\frac{\alpha }{2} } =Z_{\frac{0.05 }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

substituting values

$E = 1.96 * \frac{36 }{\sqrt{25} }$

$E = 14.1$

The 95% level of confidence interval is mathematically represented as

$\= x - E < \mu$

substituting values

$310- 14.1 < \mu< 310+ 14.1$

$295.9 < \mu< 324.1$

The 95% level of confidence mean that there is 95% chance that the true population mean will be in this interval
