Brittany surveyed the students in three different Chemistry classes regarding the average number of hours of sleep they get each night. She calculated the mean and standard deviation, SD, of the data and recorded the results in the table below.Class A Mean = 7.35SD = 2.92Class BMean = 6.87SD = 3.65Class CMean = 8.14SD = 3.10Use the information provided to complete the following statement.Class ( A, B, C) shows the most consistency in the number of hours slept per night because the(standard deviation, mean) is the (highest, lowest).

Given: AB ≅ AE; BC ≅ DE Prove: ∠ACD ≅ ∠ADC Complete the paragraph proof. We are given AB ≅ AE and BC ≅ DE. This means ABE is an isosceles triangle. Base angles in an isosceles triangle are congruent based on the isosceles triangle theorem, so ∠ABE ≅ ∠AEB. We can then determine △ABC ≅ △AED by . Because of CPCTC, segment AC is congruent to segment . Triangle ACD is an isosceles triangle based on the definition of isosceles triangle. Therefore, based on the isosceles triangle theorem, ∠ACD ≅ ∠ADC.

Clayton needs to reflect the triangle below across the line y=xWhich statements about the reflection are true? Check all that apply.Clayton could use the relationship (x,y) - (y,x) to find the points of the image.Clayton could negate both the x and y values in the points to find the points of the image.C’ will remain in the same location as C because it is on the line of reflection.C’ will move because all points move in a reflection.The image and the pre-image will be congruent triangles.The image and pre-image will not have the same orientation because reflections flip figures.

100 POINTS!!A matinee ticket costs $6 per adult and $1 per child. On a certain day, the total number of adults (a) and children (c) who saw a movie was 35, and the total money collected was $70. Which of the following options represents the number of children and the number of adults who saw a movie that day, and the pair of equations that can be solved to find the numbers? (4 points) 7 children and 28 adults Equation 1: a + c = 35 Equation 2: 6a − c = 70 7 children and 28 adults Equation 1: a + c = 35 Equation 2: 6a + c = 70 28 children and 7 adults Equation 1: a + c = 35 Equation 2: 6a + c = 70 28 children and 7 adults Equation 1: a + c = 35 Equation 2: 6a − c = 70

50 POINTS AND ILL GIVE BRAINLIEST!!!! Arionna needed to graph triangle PQR reflected across the y-axis. Her work is shown below. Which statements identify her errors? Check all that apply.Arionna did not find the correct point for P’. She should have negated the x-value, not the y-value.Arionna did not find the correct value for Q’. All points in a reflection will move.Arionna did not find the correct value for R’. She should have negated the y-value, not the x-value.Arionna’s red triangle should be reflected below the horizontal axis rather than across the vertical axis.Arionna switched the order of the coordinates of P’ (3, –7) when she graphed them.
