If the base price of a concert ticket ticket is $30 and the handling the change is 15% is added to the brace what is the total c

mel-nik [20]

Answer: $34.50

Step-by-step explanation:

Based on the information given in the question, since the base price of a concert ticket ticket is $30 and the handling the change is 15% is added to the brace, then the total cost of the ticket will be calculated thus:

= $30 + (15% × $30)

= $30 + (0.15 × $30)

= $30 + $4.5

= $34.5

Therefore, the total cost of the ticket is $34.50

4 times a number is 32 less than the square of that number. Find the negative solution.

Korvikt [17]

The answer is -16

Step by step explanation:

the expression of this equation is √4x=-32, so first, we would find the square root of 4, which is 2. so now we have 2x=-32. Next we want to divide 2 from both sides, which gives us our final result: x=-16. So our answer is -16.

According to the Vivino website, the mean price for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System i

lozanna [386]

Answer:

a

The null hypothesis is $H_o : \mu = 32.48$

The alternative hypothesis is $H_a : \mu < 32.48$

b

$t = -1.504$

c

There is no sufficient evidence to conclude that the mean price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48

Step-by-step explanation:

From the question we are told that

The mean price of is $\mu = \$ 32.48$

The sample size is n = 56

The sample mean is $\= x = \$30.15$

The standard deviation is $\sigma = \$12$

The null hypothesis is $H_o : \mu = 32.48$

The alternative hypothesis is $H_a : \mu < 32.48$

Generally the test statistic is mathematically represented as

$t = \frac{\= x - \mu }{\frac{\sigma }{\sqrt{n} } }$

=> $t = \frac{30.15 - 32.48 }{\frac{12 }{\sqrt{60} } }$

=> $t = -1.504$

Generally the p-value is mathematically represented as

$p-value = P (t < -1.504 )$

From the z-table

$P(t < -1.504) = 0.066291$

So

$p-value = 0.066291$

From the value we obtain we see that

$p -value > \alpha$

Then we fail to reject the null hypothesis

Hence there is no sufficient evidence to conclude that the mean price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48
