Please help me solve this
Nataly_w [17]

Answer:

x = 24

Step-by-step explanation:

using the rule of exponents

a^{m} × a^{n} = a^{(m +n)}

consider left side

5^{\frac{x}{6} } × 5^{\frac{x}{2} }

= 5^{\frac{x}{6} } × 5^{\frac{3x}{6} }

= 5^{\frac{4x}{6} }

then

5^{\frac{4x}{6} } = 5^{16}

since the bases on both sides are equal, both 5 then equate exponents

\frac{4x}{6} = 16 ( multiply both sides by 6 )

4x = 96 ( divide both sides by 4 )

x = 24

At a large company banquet for several thousand employees and their families, many of the attendees became ill the next day. The
yan [13]

Answer:

a. Yes.  This provides convincing evidence that the true proportion of all attendees who ate the fish that got sick (80%) is more than the true proportion of all attendees who did not eat the fish that got sick.

b. The mistake here would have been the rejection of the Doctor's theory or hypothesis to the effect that more attendees who ate the fish got sick than those who did not eat the fish. This is a Type 1 error.   A Type 1 error occurs when a null hypothesis is rejected when it is true. On the other hand, a Type II error occurs when the null hypothesis is accepted when it should be rejected.  While a Type I error is equivalent to a false positive, a Type II error is equivalent to a false negative.

Step-by-step explanation:

Total number of attendees who ordered fish = 1,000

Sample size of the attendees who ate fish = 80

Number of attendees who ate the fish and got sick = 64 (80% or 64/80)

Sample size of attendees who did not eat fish = 60

Number of attendees who did not eat fish and got sick = 39 (65% or 39/60)
