) What proportion of the sampled wafers had at least one particle? At least five particles? (Round your answers to two decimal places.)
Answer:
0.99
0.71
Step-by-step explanation:
The total number of frequency is 100 when added together
A.
The proportion with at least one particle.
Here we are to get :
Total frequency - (frequency of cases whose particles are 0.)
= 100-1
= 99
99/100
= 0.99
B.
At least 5 particles:
Total number of frequency - (cases that have frequencies with 4 or less particles)
= 100 - (12+11+3+2+1)
= 100 - 29
= 71
71/100
= 0.71

Step-by-step explanation:
The tangent function relates an angle to the opposite and adjacent sides of a right triangle:
Tan = Opposite/Adjacent
Here, we're looking for the measure of the side opposite the angle, so we can rearrange this relation to ...
Opposite = Adjacent×Tan
__
2. x = 32×tan(29°) ≈ 17.74
3. x = 13×tan(52°) ≈ 16.64

Step-by-step explanation:
55+30=85
The three angles together will equal 180 so 180-85=95. That would give you y. Y and X and vertical angles and since vertical angles are congruent and y=95 X has to also equal 95
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 432 gram setting. It is believed that the machine is underfilling the bags. A 29 bag sample had a mean of 425 grams with a standard deviation of 26. Assume the population is normally distributed. A level of significance of 0.02 will be used. Find the P-value of the test statistic. You may write the P-value as a range using interval notation, or as a decimal value rounded to four decimal places.
Answer:
-2.154
Step-by-step explanation:
We are given;
Population mean; μ = 432
Sample mean; x¯ = 425
Sample size; n = 29
standard deviation; σ = 26
Hypothesis is defined as;
Null hypothesis; H0: μ ≥ 432
Alternative hypothesis: Ha: μ < 432
Formula for the test statistic since sample size is less than 30 is;
t = (x¯ - μ)/(σ/√n)
Plugging in the relevant values;
t = (425 - 432)/(26/√29)
t = -1.45
Now,we are given significance level of 0.02; our DF = n - 1 = 29 - 1 = 28
From t-table attached, we can see that at DF of 28 and significance value of 0.02, the critical value is 2.154
However, this is a left tailed test as the rejection region is to the left.
Thus, the critical value of a left tailed test is negative. Thus, in this case our critical value will be -2.154
Choose a value for dilation to place triangle ABC on top

Describe how the triangle moves when it is dilated.
O The triangle changes size, but not shape.
The triangle changes shape.
O The triangle flips upside down.
O The triangle completes a full turn.
Dilation
Answer:
a
Step-by-step explanation:
The required, the triangle changes size, but not shape. Option A is correct.
Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.
Here,
A dilation to place triangle ABC on top of triangle DE is the triangle changes size, but not shape. Because it is necessary property of dilation. Since dilation only helps to scale the figure. In the question it is mention that shifting of triangle through dilation there is why triangle must be scale to shift over one another
Thus, the required, the triangle changes size, but not shape. Option A is correct.

There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a red marble is 8/9.
There are 63 marbles in total in the bag and each is equally likely to be chosen.
Work out how many red marbles there must be.
If the probability of picking a red marble out of the total 63 is 8/9, then it's reasonable to think that 8/9 of the total number of marbles must be red. So there are likely 8/9 × 63 = 56 red marbles in the bag.

what is the answer to this word equation? h +(2h - 1000) = 4400
Answer:
h+2h−1000=4400
Step 1: Simplify both sides of the equation.
h+2h−1000=4400
h+2h+−1000=4400
(h+2h)+(−1000)=4400(Combine Like Terms)
3h+−1000=4400
3h−1000=4400
Step 2: Add 1000 to both sides.
3h−1000+1000=4400+1000
3h=5400
Step 3: Divide both sides by 3.
3h3=54003
h=1800
Answer:
h=1800
Answer:
h = 1800
Step-by-step explanation:
Equations
Solve the following equation:
h + (2h - 1000) = 4400
Remove the parentheses. No changes are done because it doesn't have any operation of multiplication or division:
h + 2h - 1000 = 4400
Joining like terms on the left side:
3h - 1000 = 4400
Adding 1000:
3h = 5400
Dividing by 3:
h = 5400/3 = 1800
h = 1800

Step-by-step explanation:
The angle measure for 60 degrees and its corresponding side which measures 14 is greater than the measure of 50 degrees and its corresponding side which measures 12.4. That's correct. The reason Hector was incorrect is because the angle measure for 60 degrees and its corresponding side measured 12.4 was less than the measure of 50 degrees and its corresponding side that measured 14. 60 degrees is greater than 50 degrees, then the corresponding side for the angle that measures 60 degrees should be greater than the corresponding side for the angle that measures 50 degrees.

Original price is $56. Discount is 25%. what is the sales price
Answer:
Sale Price = $42 (answer). This means the cost of the item to you is $42. You will pay $42 for a item with original price of $56 when discounted 25%. In this example, if you buy an item at $56 with 25% discount, you will pay 56 - 14 = 42 dollars.
Step-by-step explanation:
Answer:
$42
Step-by-step explanation:
The original price is $56.
The discount is 25% off.
To solve the equation, turn 25 into a decimal. The you multiply it by 56.
25 to a decimal = 0.25
56 * 0.25 = 14
The answer is 14. That means the thing that is being bought is $14 off.
So, you have to subtract 56 and 14.
56 - 14 = 42
