An education researcher is comparing four different algebra curricula. Eighth grade students are randomly assigned to one one of the four groups. Their state achievement test scores are compared at the end of the year. Use the appropriate statistical procedure to determine whether the curricula differ with respect to math achievement. An alpha criterion of .05 should be used for the test.
n mean std
curriculum 1 50 170.5 14.5
curriculum 2 50 168.0 12.8
curriculum 3 50 167.6 17.7

Which of the following represents the measures of all angles coterminal with a -220° angle?
O 360 + 140n, for any whole number n
O 360 + 140n, for any integer n
O 140 + 360n, for any whole number n
O 140 + 360n, for any integer n
The measurement of all angles co-terminal with a -220° angle is represented by 140+ 360 n, for any integer number n.
What are Co-terminal angles?These are the angles which shares the same initial line or terminal side. They are obtained by adding or subtracting 360° from the given angles.
Given, angle is -220° then its one positive co-terminal angle= -220°+360 = 140°
So, 140° is a positive co-terminal angle of -220°.
Therefore, co-terminal angle must be the type of 140°+360° n,

( Need Help Now!!!!!!) Noelle has four times as many apples in her grocery bag as her friends Dakota and Kylie combined. Dakota has 1 apple in her bag. Noelle has 16 apples in her bag. How many apples does Kylie have in her grocery bag? The equation 4(x + 1) = 16 models this situation. Which choice shows the sequence of operations needed to solve this problem, using both arithmetic and algebra?
Answer:
3 Apples
Step-by-step explanation:
3 + 1 = 4, 4 x 4 = 16 Apples :D
Answer:
The answer is 6 Apples
Step-by-step explanation:
You have to ad 3+2 equals 4 then 4 times 4 is 16 so the answer is 16 apples.
3 + 1 = 4, 4 x 4 = 16 Apples

Answer:
See bolded answers
Step-by-step explanation:
Since 1=100%, then 1.15=115%, meaning x increased by 15% is correct
Since 1=100%, then 0.15=15%, meaning 15% of x is correct
Since 1=100%, then 0.85=85%, meaning x decreased by 15% is correct
Help please! This has to do with the Pythagorean theorem.
Answer:
x = 11.49
Step-by-step explanation:
Apply the pythagorean theorem to find x
Thus:
a² + b² = c²
Where,
a = x = ???
b = 8
c = 14 (hypotenuse)
Plug in the values
x² + 8² = 14²
x² + 64 = 196
x² = 196 - 64 (subtraction property of equality)
x² = 132
x = √132
x = 11.49 (approximated to nearest hundredth)

y ≥ 12x – 1
y < 43x – 2
Answer:
Step-by-step explanation:
The solution to this problem is a graph.
Graph y ≥ 12x - 1: this is a straight solid line with slope 12 and y-intercept -1. Due to the presence of the ≥ operator, we must shade (darken) the entire area above this line.
Next, graph y < 43x – 2 using a dashed line (due to the < operator): The slope is 43 and the y-intercept is -2.
Determine where the two lines intersect, either from the graph or algebraically. If algebraically:
equate the two givens:
y = 12x - 1 = y = 43x – 2, which simplifies first to:
12x - 1 = 43x - 2, and second to
1 = 43x - 12x = 31x, which results in x = 1/31.
Substituting 1/31 for x in the first equation, we get:
y = 12(1/31) - 1, or y = 12/31 - 1, or y = 12/31 - 31/31, or y = 19/31
The two graphs intersect at (1/31, 19/31)
Shade (darken) the area beneath (under) the dashed line y < 43x – 2.
The solution is the area that you have darkened twice.
