Step-by-step explanation:

As x approaches negative infinity, h(x) approaches positive infinity / negative infinity, which is an indeterminate form.

Therefore we use L'Hospital's Rule:

Derivative = 30x⁵ / 7x⁶ = 30 / (7x)

As x approaches negative infinity, 30 / (7x) approaches 0, and it comes from below because it is a rational graph with positive coefficient.

Hence the anewer is C.

Answer:

The answer is "0.7794".

Step-by-step explanation:

Please find the complete question in the attached file.

Given:

$\to n_{1}=n_{2}=25\\\\$

Hypotheses:

$\to H_{0}:\mu_{B}-\mu_{A}\geq 0\\\\\to H_{a}:\mu_{B}-\mu_{A}< 0\\\\$

Testing statistics:

$\to z=\frac{(\bar{x}_{B}-\bar{x}_{A})-(\mu_{B}-\mu_{A})}{\sqrt{\frac{\sigma^{2}_{B}}{n_{1}}+\frac{\sigma^{2}_{A}}{n_{2}}}}=\frac{3.5-(0)}{\sqrt{\frac{16^{2}}{25}+\frac{16^{2}}{25}}}=0.77$

The test is done just so the p-value of a test is

$\to p-value = P(z < 0.77) = 0.7794$

Because the p-value of the management is large, type B can take it.

Answer: the number of roses sold is 69 while number of tulips is 37

Step-by-step explanation:

Let x represent the number of roses that the flower shop sold.

Let y represent the number of tulips that the flower shop sold.

The number of roses sold was 5 less than twice the number of tulips sold. This means that

x = 2y - 5 - - -- -- - - - - - ;1

If the shop sold 106 flowers in total, it means that

x + y = 106

Substituting x = 106 - y into equation 1, it becomes

106 - y = 2y - 5

3y = 106 + 5 = 111

y = 111/3 = 37

x = 106 - y = 106 - 37

x = 69
