What is the measure of ABD?
A 32
B 58
C 64
D 148
E 180
Answer: The answer is 148
Step-by-step explanation:
Angle CBA and ABD should add up to 180 degrees. So you just do 180-32=148
The measurement of the ∠ABD in the given figure is 148°.
Hence the correct option is D.
Given that are two lines AE and CD are intersecting at point B, making angle ∠ABC = 32°.
We need to find the measurement of the ∠ABD.
To find the measurement of the ∠ABD, we will use the concept of linear pair angles.
According to the figure, angles ABC and ABD are linear pair angles, that mean they are supplementary, or we can say their sum is 180°.
Therefore, setting up the equation.
∠ABC + ∠ABD = 180°
Plugging the value of angle ABC from the given information,
32° + ∠ABD = 180°
Subtracting 32 from both the sides,
∠ABD = 180° - 32°
∠ABD = 148°
Hence the angle ABD is equal to 148°.
Therefore, the correct option is D.

In a certain mathematics examination, the probability of being award a grade A is believed to be 0.3
For a group of 10 candidates, calculate:
i) the probability that at least half achieve grade A
The probability of being awarded a grade B is also 0.3
ii) Find the probability that all ten candidates achieve either grade A or grade B
Answer: (i) 15% (ii) 0.6%
Step-by-step explanation:
Given: P(A) = 0.3 ⇒ ~P(A) = 0.7
P(B) = 0.3 ⇒ ~P(B) = 0.7
P(A ∪ B) = 0.6 ⇒ ~P(A ∪ B) = 0.4
If you don't have a calculator function for the Binomial Formula, the equation is: [tex]P(X)=\dfrac{n!}{X!(n-X)!}\cdot p^X\cdot (1-p)^{n-X}[/tex] where
n is the number of trialsp is the probability of successX is the number of successes(i) Probability of at least 5 --> P(X ≥ 5) means P(5) + P(6) + P(7) + P(8) + P(9) + P(10)
P(5): n = 10, p = 0.3, X = 5 → P(5) = 0.1029
P(6): n = 10, p = 0.3, X = 6 → P(6) = 0.0368
P(7): n = 10, p = 0.3, X = 7 → P(7) = 0.0090
P(8): n = 10, p = 0.3, X = 8 → P(8) = 0.0014
P(9): n = 10, p = 0.3, X = 9 → P(9) = 0.0001
P(10): n = 10, p = 0.3, X = 10 → P(10) = 0.0000
TOTAL = 0.1502 → 15.02%
(ii) Probability of A or B = 10 --> P(X = 10)
P(10): n = 10, p = 0.6, X = 10 → P(10) = 0.0060 → 0.6%
a = √7 + √c and b = √63 + √d where c and d are positive integers.
Given that c: d = 1: 9
find, in its simplest form, the ratio a: b
Answer:
[tex]\displaystyle a:b=\frac{1}{3}[/tex]
Step-by-step explanation:
Ratios
We are given the following relations:
[tex]a=\sqrt{7}+\sqrt{c}\qquad \qquad[1][/tex]
[tex]b=\sqrt{63}+\sqrt{d}\qquad \qquad[2][/tex]
[tex]\displaystyle \frac{c}{d}=\frac{1}{9} \qquad \qquad [3][/tex]
From [3]:
[tex]9c=d[/tex]
Replacing into [2]:
[tex]b=\sqrt{63}+\sqrt{9c}[/tex]
We can express 63=9*7:
[tex]b=\sqrt{9*7}+\sqrt{9c}[/tex]
Taking the square root of 9:
[tex]b=3\sqrt{7}+3\sqrt{c}[/tex]
Factoring:
[tex]b=3(\sqrt{7}+\sqrt{c})[/tex]
Find the ration a:b:
[tex]\displaystyle a:b=\frac{\sqrt{7}+\sqrt{c}}{3(\sqrt{7}+\sqrt{c})}[/tex]
Simplifying:
[tex]\boxed{a:b=\frac{1}{3}}[/tex]

Find the Simplify interest earned $720, 5% 2 years A. 74 B.73 C.75 D.72 PLZZZZZZ HELP ME ANYNONE ;(
Answer:
Option D, 72
Step-by-step explanation:
Before touching the question, Let me tell you something about simple interest.
Simple Interest: It is something that is calculated for the additional amount paid on a loan amount. The formula for simple Interest is given by, SI = (P × R × T)/100 where, P specifies principal, R specifies rate, and T denotes time.
Now, Let's go for solving the question.
Simple Interest = P × R × T/100
0r, Simple interest = (720 × 5 × 2)/100
0r, Simple Interest = 72 × 2 × 5/10
0r, Simple Interest = 72
Hence, 72 is the required answer.
