Answer:
Read the claim. Schools should stop doing standardized testing. Read the counterclaim. The Department of Education says that teaching students to do well on standardized tests helps to motivate students and keep them focused on important subjects. Read the rebuttal. On the contrary, being forced to focus on testing stresses students and limits the amount of knowledge they can gain. How can the writer revise the rebuttal to make it stronger

¿Cuánto es el interés simple de $800.00 al 3.5 % durante un año?
Answer:
$28
Step-by-step explanation:
given that
The Principal amount is $800
The rate of interest is 3.5%
And, the time period is one year
we need to find out the simple interest
As we know that
Simple interest = Principal × rate × time period
= $800 × 3.5% × 1 year
= $28
hence, the simple interest is $28

Answer:
900 pi for first question and 14137 for 2nd
Step-by-step explanation:
SA=4pi r^2
r=15 (30/2)
SA=4pi(15^2)
SA=900pi
V=4/3pi r^3
V=4/3(3.14)(15^3)=14137
Answer:
Surface area: 900π in²
Volume: 4500π in³
Step-by-step explanation:
A = 4πr² = 4π(15²) = 900π
V = 4/3 πr³ = 4/3 π(15³) = 4500π
A study published in Psychiatry Research states that 62% of autistic children are left-handed.[12]
A local resource for children with autism, Central Coast Autism Learning Partners, is curious to see
if their set of autistic children show a similar proportion of being left-handed. When a random
sample of 26 autistic children were observed, 17 were found to be left-handed. Is there enough
statistical evidence based on the sample to dispute the results of the study published in Psychiatry
Research? Use the P-value method and let
a=.05.
Answer:
The pvalue of the test is 0.7188 > 0.05, which means that there is not enough statistical evidence based on the sample to dispute the results of the study published in Psychiatry Research.
Step-by-step explanation:
Test if there is enough statistical evidence based on the sample to dispute the results of the study published in Psychiatry Research:
This means that at the null hypothesis we test if the proportion is 62%, that is:
[tex]H_0: p = 0.62[/tex]
At the alternate hypothesis, we test if the proportion is different from 0.62, that is:
[tex]H_a: p \neq 0.62[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample
62% is tested at the null hypothesis:
This means that [tex]\mu = 0.62, \sigma = \sqrt{0.62*0.38}[/tex]
When a random sample of 26 autistic children were observed, 17 were found to be left-handed.
This means that [tex]n = 26, X = \frac{17}{26} = 0.6538[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.6538 - 0.62}{\frac{\sqrt{0.62*0.38}}{\sqrt{26}}}[/tex]
[tex]z = 0.36[/tex]
Pvalue of test and decision:
The pvalue of the test is the probability of a proportion that differs from the mean by at least 0.6538 - 0.62 = 0.0338, which is P(|z| > 0.36), which is two multiplied by the pvalue of z = -0.36
Looking at the z-table, z = -0.36 has a pvalue of 0.3594
2*0.3594 = 0.7188
The pvalue of the test is 0.7188 > 0.05, which means that there is not enough statistical evidence based on the sample to dispute the results of the study published in Psychiatry Research.

A dodecahedral die (one with 12 sides numbered from 1 to 12) is tossed once. Find the following probability. (Enter your probability as a fraction.)
The number on the upward face is not 4.
Answer:
11/12
Step-by-step explanation:
::::::::::::::::
The probability of the number on the upward face is not 4 would be 11/12 or 0.92 by calculating as follows:
Solution:
The possible outcomes for rolling a dodecahedral die, numbered from 1 to 12, once is given below in the term of sample space S:
S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.
Therefore,
n(S) = 12
Event A: Sample space in the case of not having number 4 on the upward face:
A = {1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 12}
therefore,
n(A) = 11
the probability of an event can be calculated by:the required probability = [tex]\dfrac{\text{Number of times event A, occurred}}{\text{Number of times this experiment performed}}[/tex]
then putting the space values here;
= [tex]\frac{n(A)}{n(S)}=\frac{11}{12}=0.92[/tex]
Thus, the required probability is 0.92

Answer:
y = ½x + 8
Step-by-step explanation:
✔️First, find the slope (m) using any two given pairs of values, say (0, 8) and (2, 9):
Slope (m) = change in y/change in x
Slope (m) = (9 - 8)/(2 - 0)
Slope (m) = 1/2
m = ½
✔️Find the y-intercept (b):
The y-inteeceot of the function would be the value of y when x = 0.
Form the table, when x = 0, y = 8. Therefore:
y-intercept (b) = 8
✔️To write the equation of the function, substitute m = ½ and b = 8 into y = mx + b.
Thus:
y = ½x + 8

the sum of 2 numbers is 56.twice the smaller number exceeds one-half the larger number by 22.find the numbers
9514 1404 393Answer:
20, 36
Step-by-step explanation:
Let x and y represent the smaller and larger numbers, respectively. The given relations let us write two equations:
x + y = 56 . . . . . . the sum of the two numbers is 56
2x -y/2 = 22 . . . . twice the smaller exceeds half the larger by 22
We can solve this by multiplying the second equation by 2 and adding the first.
2(2x -y/2) +(x +y) = 2(22) +56
5x = 100 . . . . . . simplify
x = 20
y = 56 -20 = 36
The two numbers are 20 and 36.

An isosceles triangle has an angle that measures 116°. Which other angles could be in that isosceles triangle? Choose all that apply.
Answer:
Step-by-step explanation:
since we know that triangles have 180° we know that 116° is two much if it's doubled 2*116 = 232° so that angle has to be the single angle and the left over of 180 - 116 is the left over amount that is even divided into the last two angles so 180 - 116 = 64 / 2 = 32° so the triangle is made up of 116 + 32 + 32 degree angles
