Answer:
In general , While estimating a bodies temperature that temperature is not the same for long, the temperature of the body is not at homeostasis, the temperature constantly has bumps and drops in the temperature this causes in accuracy thats why the thermometer takes 10-20 seconds because it takes the average of all the temperature's so it is accurate, that is a difficulty when estimating temperature because estimates are not good and the temperature keeps having ups and downs.
Express each of the following subsets with bit strings (of length 10) where the ith bit (from left to right) is 1 if i is in the subset and zero otherwise.
Subsets with bit strings:
001110000010100100010111001110What are subsets?A set A is a subset of a set B if all of its items are also elements of B; B is, therefore, a superset of A. A and B can be equal; if they are unequal, then A is a legitimate subset of B. Inclusion refers to the relationship of one set being a subset of another.To find the subsets with bit strings:
We need to express a) b) and c) into bit strings.
Firstly, a number of elements in the universal set represent the number of bits in the bit string.
Secondly, 1 = yes element is present in both universal sets as well as in subset.
0 = No, the element is not present in the subset but present in the universal set.
Hence, we have:
a) Subset {3,4,5} = 0011100000 (As there are 3 1's which means only 3,4,5 are present in both universal set and subset.
Similarly,
b) Subset {1, 3, 6, 10} = 1010010001
c) Subset {2, 3, 4, 7, 8, 9} = 0111001110

The height, h, in feet of a ball suspended from a spring as a function of time, t, in seconds can be modeled by the equation h = a sine (b (t minus h)) k. what is the height of the ball at its equilibrium?
Based on the height of the ball suspended from a spring, the height of the ball at equilibrium is K feet.
What is the ball's height at equilibrium?The model for the height of the ball when it is suspended from a spring is shown as:
= aSin(b ( t - h)) + k
Given this, we can infer the value of h by looking at the general form of the Sin function which is:
y = Asin(Bx) + c
In the above:
A = amplitude
B = (2 x pi) / Period
C = midline
Comparing the function and the general Sin function, we notice that:
C = K
If C = K then it means that K is the height of the ball at its equilibrium because C as the midline represents the equilibrium height.
In conclusion, the height of the ball at equilibrium is K feet.

The average weight of 3 men a, b and c is 84 kg. another man d joins the group and the average now becomes 80 kg. if another man e whose weight is 3 kg more than that of d, replaces a then the average weight of b, c, d and e becomes 79 kg. what is the weight of a?
The weight of A is 75kg.
How to calculate the weight?Total weight of A + B + C = 84 x 3 = 252kg
Total weight of A + B + C + D = 80 x 4 =.320 kg
Weight of D = 320 - 252 = 68 kg
Given, E = D + 3 = (68 + 3) kg = 71 kg
Total weight of B + C + D + E = (79 x 4) = 316 kg
Weight of B + C = 316 kg - 71 kg - 68 kg = 177 kg

If a person stands at a point and looks up at an object, the angle between their horizontal line of sight and the object is called the angle of elevation.
To find how tall the flagpole is, model as a right triangle and solve using the tan trigonometric ratio.
Tan trigonometric ratio
[tex]\sf \\tan(\theta)=\dfrac{O}{A}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleGiven information:
Person height = 1.6 mHorizontal distance (from person to flagpole) = 35 mAngle of elevation = 65°Therefore:
[tex]\theta[/tex] = 65°O = height of flagpole less height of personA = 35 mAs the person is 1.6 m tall, we model the line of sight as 1.6 m above ground level. Therefore, when calculating the height of the flagpole, we will need to add the height of the person to the value found using the trig ratio.
Substitute the given values into the formula and solve for O:
[tex]\implies \sf \tan(65^{\circ})=\dfrac{O}{35}[/tex]
[tex]\implies \sf O=35\tan(65^{\circ})[/tex]

To prove that triangles are similar, you must show that the 3 angles in one triangle are equal to the 3 angles in the other triangle. We know that they both have a 50 degree angle. We can also see that they both have a right angle. That means that the 3rd angle must also equal 40 (180-90-50). So by AAA the two triangles are congruent.

In a mathematics test, Jack scored 17 marks more than Yazid while Susan scored twice Yazid's score. If their total score is 161, what is Jack's score?
Answer:
53
Step-by-step explanation:
Let yazid's score be x
x + x + 17 + 2x = 161
4x + 17 = 161
4x = 144
x = 36
jack = x + 17
jack = 53
Answer:
Jack: 36
Bonus: Yazid: 53 and Susan: 72
Step-by-step explanation:
Let J, Y, and K stand for Jack, Yazin, Susan's scores.
We are told that:
J = Y + 17 [Jack scored 17 marks more than Yazid]
S = 2Y [Susan scored twice Yazid's score]
J + Y + S = 161 [total score is 161]
Substitute the first two expressions into the last equation:
J + Y + S = 161
(Y+17) + Y + (2Y) = 161
4Y = 144
Y = 36
Use Y = 36 to find the other scores:
J = Y + 17
J = 36 + 17
J = 53
S = 2Y
S = 2*(36)
S = 72

Does 36+53+72 = 161?

the width of a rectangle is 9 inches less than its length and the area is 36 square inches. what are the length and width of the rectangle
Answer:

Step-by-step explanation:
Let x= length
If you draw a rectangle. two sides would be the length x. The other two sides would be (x-9).
(length)(width) = Area
(x)(x-9) = 36
x^2 - 9x = 36 Substitute in x and x-9 for the length and width
x^2 - 9x - 36 =0 Subtract 36 from both sides
(x-12)(x+3) = 0 We are looking for 2 number that add to -9 and mult. to -36
x-12=0 and x+3=0 Set both factors to 0 and solve
x = 12 and x =-3. It does not make sense that a length could be -3 so we reject that answer. If the length is 12, then the width is 3

P(E and F)=
(Simplify your answer.)
E and F are two events and that P(E)=0.3 and P(F|E)=0.5. Thus, P(E and F)=0.15
Bayes' theorem is transforming preceding probabilities into succeeding probabilities. It is based on the principle of conditional probability. Conditional probability is the possibility that an event will occur because it is dependent on another event.
P(F|E)=P(E and F)÷P(E)
It is given that P(E)=0.3,P(F|E)=0.5
Using Bayes' formula,
P(F|E)=P(E and F)÷P(E)
Rearranging the formula,
⇒P(E and F)=P(F|E)×P(E)
Substituting the given values in the formula, we get
⇒P(E and F)=0.5×0.3
⇒P(E and F)=0.15
∴The correct answer is 0.15.

Step-by-step explanation:
remember, the sum of all angles in a triangle is always 180°.
and the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
with a, b, c being the sides opposite of their associated angles (A, B, C).
1)
17/sin(26) = 12/sin(C)
sin(C) = 12×sin(26)/17 = 0.309438457...
C = 18.02539254...° ≈ 18°
3)
180 = 27 + 115 + C
C = 38°
19/sin(38) = AC/sin(27)
AC = 19×sin(27)/sin(38) = 14.01065332... in ≈ 14 in
In first triangle side angle m∠C is 18° and in first triangle side AC is 14 in. This can be obtained by using the law of sine.
Find the required angle and side:We know the law of sine which is,
If in a triangle, Δ ABC,
[tex]\frac{sin A}{a} =\frac{sin B}{b}= \frac{sinC}{c}[/tex], where a is the side opposite to the angle m∠A, b is the side opposite to the angle m∠B and c is the side opposite to the angle m∠C.
sine of the angle scan be found using calculator.
From the question,
1) In first triangle side,
AB = 12ft, BC = 17 ft and m∠A=26°
⇒By using the law of sine,
[tex]\frac{sin A}{a} =\frac{sin B}{b}= \frac{sinC}{c}[/tex]
sin 26°/17 = sin B/AC = sin C/12
sin 26°/17 = sin C/12
12×sin 26° = 17×sin C
sin C = 5.26/17 = 0.3091
C = 18.023° ≈ 18°
3) In second triangle side,
m∠B = 27°, AB = 19 in and m∠A = 115°
m∠A + m∠B +m∠C = 180°
115° + 27° + m∠C = 180°
142° + m∠C = 180°
m∠C = 38°
⇒By using the law of sine,
[tex]\frac{sin A}{a} =\frac{sin B}{b}= \frac{sinC}{c}[/tex]
sin 115°/BC = sin 27°/AC = sin 38°/19
sin 27°/AC = sin 38°/19
sin 27° × 19 = sin 38° × AC
8.63 = 0.62 × AC
AC = 13.91 in ≈ 14 in.
Hence in first triangle side angle m∠C is 18° and in first triangle side AC is 14 in.
