Step-by-step explanation:
In order to do this you have to understand PEMDAS, which stands for Parentheses,Exponents,Multiplication,Division,Addition,Subtraction. This basically tells us what order we have to do the equation in. So first up, do we have any parentheses? No. Do we have any exponents? No. Okay now, this is what you have to understand. Multiplication and division are on the same level, meaning that if there is any multiplication or division, we do whatever comes first. This also goes for addition and subtraction.
This might sound a bit confusing but let's try! Since division is first, let's do it.
36 divided by 2 is 18.
That means the equation is...
18 x 4+12.
Since multiplication comes after, let's do multiplication now.
18 x 4 =72.
That means the equation is now...
72+12.
Now, our final step is to do addition, so 72+12=84. The answer is 84!

Find the measure of the angle given below
Answer:
can you post a pic pls
Step-by-step explanation:
=============================================================
Explanation:
You subtract the arc measures, and then divide the result in half.
The order of subtraction is larger arc minus smaller arc.
Angle ABC = ( (arc AC) - (arc DE) )/2
Angle ABC = (90 - 40)/2
Angle ABC = 50/2
Angle ABC = 25 degrees
Side note: segments AB and BC are considered secant segments.
The next section will go into a more in-depth look. The next section is optional.
-------------------------------------
Alternative Method:
Refer to the diagram below. I've added points D and E to the diagram.
Based on those points, let
x = measure of minor arc CEy = measure of minor arc DANote how inscribed angle CAB subtends the arc CED. The measure of arc CED is 40+x. Half this is (40+x)/2, which is the measure of inscribed angle CAB. Through similar logic, inscribed angle ACB is (40+y)/2.
Also, note how the four arc pieces of the full circle are: AC = 90, EC = x, DE = 40, and AD = y.
The four arc pieces must add to 360 as they form a full circle
AC+EC+DE+AD = 360
90+x+40+y = 360
x+y+130 = 360
x+y = 360-130
x+y = 230
y = 230-x
From this, we can rewrite the expression for inscribed angle ACB
angle ACB = (40+y)/2
angle ACB = (40+230-x)/2
angle ACB = (270-x)/2
Now because the interior angles of a triangle must add to 180, we can then use this fact to find angle ABC
(angle ABC) + (angle CAB) + (angle ACB) = 180
angle ABC = 180 - (angle CAB) - (angle ACB)
angle ABC = 180 - (40+x)/2 - (270-x)/2
angle ABC = 180 - 40/2 - x/2 - 270/2 + x/2
angle ABC = 180 - 20 - x/2 - 135 + x/2
angle ABC = 25 degrees
Ultimately the x terms cancel out when we combine the -x/2 and +x/2 together.
A random sample of 11 fields of rye has a mean yield of 20.1 bushels per acre and standard deviation of 7.66 bushels per acre. Determine the 80% confidence interval for the true mean yield. Assume the population is approximately normal. Round your answer to one decimal place.
Answer:
17.1≤x≤23.1
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as;
CI = x ± z*s/√n
x is the mean yield = 20.1
z is the 80% z-score = 1.282
s is the standard deviation = 7.66
n is the sample size = 11
Substitute
CI = 20.1 ± 1.282*7.66/√11
CI = 20.1 ± 1.282*7.66/3.3166
CI = 20.1 ± 1.282*2.3095
CI = 20.1 ±2.9609
CI = (20.1-2.9609, 20.1+2.9609)
CI = (17.139, 23.0609)
hence the required confidence interval to 1dp is 17.1≤x≤23.1
Consider the triangle below
Is w = 13 a solution of the inequality 8 < w - 5? Yes or no?
Answer: not a solution
Step-by-step explanation:
plug it into the inequality
8 < 13 - 5
8 < 8
it is not true because 8 is not less than 8
therefore it is not a solution
which values are solutions to the inequality below? √x > 25?
Answer:
C and D
Step-by-step explanation:
So basically when u square -5 or +5, u get 25 either way
And since the square root of x is greater than or equal to 25, u can use both of them for answers.

Given that:
The number of suitcases on a flight caring 250 passengers.To Find:
The number of suitcases.Equation:
y = 1.98x + 7.97Where,
x = Number of passengers y = Number of suitcasesFinding the number of suitcases:
⟶ y = 1.98x + 7.97
⟶ y = 1.98(250) + 7.97
⟶ y = 495 + 7.97
⟶ y = 502.97 ≈ 503

Find the area and explain how you did it
Could someone help me please?
Answer:
1150 sq cm.
Step-by-step explanation:
22*45+20*8= 1150 sq cm.
Answer: 1150 cm^2
Step-by-step explanation:
find the area of the rectangle above the dotted line and the area of the one below the dotted line, then add those areas together
so for the rectangle above the area would be 22 * 45 = 990 cm^2
for the lower one the area is 20 * 8 = 160 cm ^2
now add those two together
990 + 160 = 1150
so the total area of the figure would be 1150 cm^2
hope this helped :))

A submarine travels 8.6 km due North from its base and then turns and travels due West for 11.4 km. How far away is the submarine from its base? Give your answer rounded to 1 DP.
Answer:
The submarine is 14.28 kilometers away from its base.
Step-by-step explanation:
Given that a submarine travels 8.6 km due North from its base and then turns and travels due West for 11.4 km, to determine how far away is the submarine from its base the following calculation must be performed, applying the Pythagorean Theorem:
8.6 ^ 2 + 11.4 ^ 2 = X ^ 2
73.96 + 129.96 = X ^ 2
√203.92 = X
14.28 = X
Therefore, the submarine is 14.28 kilometers away from its base.

A researcher is testing a hypothesis of a single mean. The critical z value for a = .05 and a two‑tailed test is +1.96. The observed z value from sample data is ‑2.05. The decision made by the researcher based on this information is to _____ the null hypothesis.
Answer:
The decision made by the researcher based on this information is to reject the null hypothesis.
Step-by-step explanation:
Two-tailed hypothesis test:
Critical value: [tex]z_c[/tex]
Test statistic: z
If [tex]|z| < |z_c|[/tex], we do not reject the null hypothesis.
If [tex]|z| > |z_c|[/tex], we reject the null hypothesis.
In this question:
[tex]z_c = 1.96, z = -2.05, |z| = 2.05[/tex]
Since [tex]|z| > |z_c|[/tex], we reject the null hypothesis.
The decision made by the researcher based on this information is to reject the null hypothesis.

Answer:
246
Step-by-step explanation:
The accounting department analyzes the variance of the weekly unit costs reported by two production departments. A sample of 16 cost reports for each of the two departments shows cost variances of 2.8 and 5.7, respectively. Is this sample sufficient to conclude that the two production departments differ in terms of unit cost variance
Answer:
We can conclude that the result is significant and production differ in cost variance.
Step-by-step explanation:
Given :
n1 = 16
n2 = 16
s1² = 5.7
s2² = 2.8
α = 0.10
H0 : σ1² = σ2²
H1 : σ1² ≠ σ2²
The test statistic :
Ftest = s1² / s2² =
Ftest = 5.7 / 2.8
Ftest = 2.036
Using the Pvalue from Fratio calculator :
df numerator = 16 - 1 = 15
df denominator = 16 - 1 = 15
Pvalue(2.036, 15, 15) = 0.0898
Pvalue = 0.0898
Since the Pvalue is < α ; We can conclude that the result is significant and production differ in cost variance.
