The values of the two supplementary angles are 89 and 1.
To arrive at this, we set the angles as A and B.
We understand that A=B+88 and A+B=90 degrees. Solving this gives A as 89 and B as 1.
Answer:
the speed value produced by the radar equipment.
Step-by-step explanation:
In an experiment, a random variable is typically referred to as a dependent variable. In this context, the random variable pertains to the speed value produced by the radar equipment. This value is reliant on the actual speeds of the cars that go past the equipment. A higher speed results in a greater value shown by the radar. Thus, it relies entirely on the automobiles.
The <span>root<span> of a numeral x represents another number that, when multiplied by itself for a specific amount of times, results in x. For instance, the square <span>root<span> of 9 is 3, given that 3 x 3 equals 9. The square <span>root<span> is the term commonly used for the second <span>root<span>. Meanwhile, the term for the third <span>root<span> is known as the cube <span>root<span>. Refer to <span>Root<span> (of a number). because then/</span>

Regardless of the value of M, it will correspond to 18m squared.
Answer:
At a confidence level of 90%, the margin of error is calculated to be 0.5133 grams.
Step-by-step explanation:
The formula for margin of error (E) is: (critical value × sample standard deviation) ÷ sqrt(n)
The sample standard deviation is 1.5 grams.
A 90% confidence level translates to 0.9.
Significance level is determined as 1 - C, which equals 1 - 0.9 resulting in 0.1 or 10%.
The sample size (n) is 25.
Degrees of freedom are calculated as n - 1, which is 25 - 1 equaling 24.
The critical value (t) for 24 degrees of freedom at a significance level of 10% is found to be 1.711.
Using these values, we calculate: E = (1.711 × 1.5) ÷ sqrt(25) = 2.5665 ÷ 5 = 0.5133 grams.
