The measurement of arc DB equals 74.57°. Step-by-step explanation: To clarify the resolution method: A secant intersects a circle in precisely two points, while a tangent intersects at just one point. When a tangent and a secant intersect outside of a circle, the formed angle's measurement is precisely half of the positive difference between the measures of the intercepted arcs. Now, applying this to the issue where secant CE intersects circle A at points D and E, while tangent CB touches circle A at B, forming angle ECB. As such, m∠ECB = 1/2 (m arc EB - m arc DB). Given m arc EB as 96° and m arc DB given as 25x + 21, along with m∠ECB as 5x, we establish the equation 5x = 1/2[96 - (25x + 21)]. After rearranging and solving, we find x = 75/35, simplifying to 15/7. Next, substituting x back into the arc DB formula gives m arc DB = 25(15/7) + 21 = 522/7 yields approximately 74.57°.

PIT_PIT [12445]
Let’s break it down:
The nine-digit number is structured as nnn,nnn,nnn

To be divisible by 100, the final two digits must be 00
In the hundred thousands position, the digit is 7
The digit in the millions place must be an even and prime number, which is 2(the only even prime)In the hundreds place, the digit is 0 (the freezing point of water at 0 °C)
The ten millions place digit is three times that of the millions position, which is 6(calculated as 2x3)
And in the thousands place, the digit is 8 (equivalent to 8 fluid ounces per cup)
Finally, the hundred millions position is 1 (the only number that divides evenly into every number)

Thus, the number is 162,708,000

PLEASE HELP MEE! the table below shows y, the average speed of a cyclist in miles per hour, and x, the time in hours that it tak
AnnZ [12381]
According to its definition, speed is determined by the distance over time.
This means that based on this definition, the last two options seem to be the plausible answers:
 Let’s analyze the third option:
 y = (3/2) * (1 / x)
 x = 12
 y = (3/2) * (1/12) = 3/24 = 1/8
 This does not comply with the table
 Now let’s assess the fourth option:
 y = (96 / x)
 x = 12
 y = (96/12) = 8
 This one fulfills the table's criteria.
 conclusion:
 y = (96 / x)

lawyer [12517]

Answer:

Step-by-step explanation:

It was noted that a music streaming platform modified its format to highlight previously unreleased tracks from emerging artists. The site manager is now aiming to assess whether the daily unique listener count has changed.

The hypothesis is set

H_0: Mean 1- Mean 2 =0\\H_a: Mean 1 - Mean 2 \neq 0

(A two-tailed test for mean difference)

The test statistic is calculated, and the p-value turns out to be 0.0743

Assuming a significance level of 5%, we observe that p-value = 0.0743>0.05

Thus, we accept the null hypothesis.

i.e. there is no statistically significant alteration in the average number of daily unique listeners

The p-value serves as an indicator of the extremity of the observed data. If p is lower than alpha, we thus reject H0; otherwise, we accept it.
