Classify the following angles as acute, Right, obtuse, straight and reflex angles.
30°,40°,120°,90°,180°,650,225°,1650,300°,170°,2150,315°,75°,
340º,170°
Answer:
any angle under 90 degrees is acute. A right angle is 90 degrees always, and obtuse angles are always above 90 degrees. Straight angles are always 180 degrees. A reflex angle is more than 180 degrees but less than 360 degrees. Hope this helps.

The decimal that is equivalent to (8 × 3)(1/10 × 1/10) is 0.24
How to determine which of the following decimals is equivalent?The expression is given as
(8×3)(110×110)
Rewrite the expression properly as follows
So, we have
(8 × 3)(1/10 × 1/10)
Evaluate the product of 8 and 3
So, we have
(8 × 3)(1/10 × 1/10) = (24)(1/10 × 1/10)
Evaluate the product of 1/10 and 1/10
So, we have
(8 × 3)(1/10 × 1/10) = (24)(1/100)
Express 1/100 as a decimal
So, we have
(8 × 3)(1/10 × 1/10) = (24)(0.01)
Remove the brackets
So, we have
(8 × 3)(1/10 × 1/10) = 24 x 0.01
This implies that
Evaluate the product of 24 and 0.01
So, we have
(8 × 3)(1/10 × 1/10) = 0.24
Hence, the decimal that is equivalent to (8 × 3)(1/10 × 1/10) is 0.24

miguel is working hard to save for a video game. he received $20 as a gift and gets $4 per week (x) in allowance. write the equation for the total amount of money he has saved, based on the number of weeks
Answer:
5
Step-by-step explanation:
x represents how much money he gets per week and if he got twenty dollars all together and gets four dollars a week then x represents 5 because 5 times 4 equals twenty and in the problem the letter that represents the number of weeks is x divide twenty by x if the number is 4 divide 20 by four and you'll get 5

What is the solution to -4 (2x +6)=-24
Answer:
x=0
Step-by-step explanation:
Distribute -4
-8x - 24 = -24
Add 24 to both sides
-8x = 0
x=0
Answer:
x=0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−4(2x+6)=−24
(−4)(2x)+(−4)(6)=−24(Distribute)
−8x+−24=−24

Step-by-step explanation:
use the given manimum and maximum data entries, and the number of classes, to find he class width, the lower class limits, and the upper class limits
minimum= 9 maximum= 66, 6 classes
The lower class and upper class limits are {9, 19, 29, 39, 49} and {10, 20, 30, 40, 50} respectively for the given class.
What is the class width of a given data set?The class width of a given class is the ratio of the difference between maximum and minimum to the number of classes.
Given, minimum= 9 maximum= 66, and classes = 6.
Therefore, class width
= [tex]\frac{maximum - minimum}{classes}[/tex]
= [tex]\frac{66 - 9}{6}[/tex]
= [tex]\frac{57}{6}[/tex]
= 9.5
Therefore, class width is 9.5.
Now, the lower class limits = {9, 19, 29, 39, 49}
The upper class limits = {10, 20, 30, 40, 50}

(Round your response to two decimal places.) The p-value for the test is nothing. (Round your response to six decimal places.) Hint: Use the Excel function Norm.S.Dist to help answer this question. Is there statistically significant evidence that the districts with smaller classes have higher average test scores? The ▼ small p-value large p-value suggests that the null hypothesis ▼ cannot be rejected can be rejected with a high degree of confidence.

Complete Question
The complete question is shown on the first uploaded image
Answer:
The 95% confidence interval is [tex] [670.03 , 673.97 ] [/tex]
The test statistics is [tex]t = 7.7 [/tex]
The p-value is [tex]p-value = 0[/tex]
The p-value suggests that the null hypothesis is rejected with a high degree of confidence. Hence there is statistically significant evidence that the districts with smaller classes have higher average test score
Step-by-step explanation:
From the question we are told that
The sample size is n = 408
The sample mean is [tex]\= y = 672.0[/tex]
The standard deviation is [tex]s = 20.3[/tex]
Given that the confidence level is 95% then the level of significance is
[tex]\alpha = (100 -95 )\% = 0.05[/tex]
From the normal distribution table the critical value of [tex]\frac{\alpha }{2} = \frac{0.05 }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }[/tex]
=> [tex]E = 1.96 * \frac{20.3}{\sqrt{408} }[/tex]
=> [tex]E = 1.970[/tex]
Generally the 95% confidence interval is mathematically represented as
[tex]\= y -E < \mu < \= y + E[/tex]
=> [tex] 672.0 -1.970 < \mu < 672.0 +1.970[/tex]
=> [tex] 670.03 < \mu < 673.97[/tex]
=> [tex] [670.03 , 673.97 ] [/tex]
From the question we are told that
Class size small large
[tex]Avg.score(\= y)[/tex] [tex]\= y_1 = 683.7[/tex] [tex]\= y_2 = 676.0[/tex]
[tex]S_y[/tex] [tex]S_{y_1} =20.2[/tex] [tex]S_{y_2} = 18.6[/tex]
sample size [tex]n_1 = 229[/tex] [tex]n_2 = 184[/tex]
The null hypothesis is [tex]H_o : \mu_1 - \mu_2 = 0[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 - \mu_2 > 0[/tex]
Generally the standard error for the difference in mean is mathematically represented as
[tex]SE = \sqrt{\frac{S_{y_1}^2 }{n_1} +\frac{S_{y_2}^2 }{n_2} }[/tex]
=> [tex]SE = \sqrt{20.2^2 }{229} +\frac{18.6^2 }{184_2} }[/tex]
=> [tex]SE = 1.913[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{\= y _1 - \= y_2 }{SE}[/tex]
=> [tex]t = \frac{683.7 - 676.0 }{1.913}[/tex]
=> [tex]t = 7.7 [/tex]
Generally the p-value is mathematically represented as
[tex]p-value = P(t > 7.7 )[/tex]
From the z-table
[tex]P(t > 7.7 ) = 0[/tex]
So
[tex]p-value = 0[/tex]
From the values we obtained and calculated we can see that [tex]p-value < \alpha[/tex]
This mean that
The p-value suggests that the null hypothesis is rejected with a high degree of confidence. Hence there is statistically significant evidence that the districts with smaller classes have higher average test score
PLEASE HELP I ONLY HAVE 10 minutes !!! (will give brainliest )........Find the perimeter of AABC with vertices A(-5, -5), B(3, -5), and C(-5, 1).
(picture is included)
Answer:
24
Step-by-step explanation:
So to start we need to find the length of the sides. luckily, since this is a right triangle we can subtract the x values on line AB to get 8 and we can subtract the y values on line AC to get 6. Now that we know two lengths we can use [tex]A^{2} +B^{2} =C^{2}[/tex] to find the last length.
When we plug in the two known lengths we get [tex]8^{2} +6^{2} =c^{2}[/tex] which can be simplified to [tex]64+36=c^{2}[/tex] and then simplified again to be [tex]100=c^{2}[/tex]. We can then take the square root of 100 to know that c=10.
Finally, we can add [tex]10+8+6[/tex] to get 24.
the total "cast" of a laptop computer is $1278.24 the local sales tax rate is 7.6% what is the retail price.
Answer:
x = 1187.96
Step-by-step explanation:
Let x = price before tax
tax = x* 7.6%
tax = .076x
The cost of the computer is price before tax plus tax
cost = x + .076x
cost = 1.076x
1278.24 = 1.076x
Divide each side by 1.076
1278.24/1.076 = 1.076x/1.076
x=1187.9553
Rounding to the nearest cent
x = 1187.96
