Park officials make predictions of times to the next eruption of a particular geyser, and collect data for the errors (minutes) in those predictions. the display from technology available below results from using the prediction errors to test the claim that the mean prediction error is equal to zero. comment on the accuracy of the predictions. use a 0.05 significance level. identify the null and alternativehypotheses, test statistic, p-value, and state the final conclusion that addresses the original claim. what are the null and alternative hypotheses? a. upper h 0h0: muμequals=00 minutes upper h 1h1: muμless than< 00 minutes b. upper h 0h0: muμequals=00 minutes upper h 1h1: muμnot equals≠00 minutes c. upper h 0h0: muμequals=00 minutes upper h 1h1: muμgreater than> 00 minutes d. upper h 0h0: muμless than< 00 minutes upper h 1h1: muμequals=00 minutes identify the test statistic. nothing

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

answer: it's a
