Answer:

67

Step-by-step explanation:

From the question given above, the following data were obtained:

Number of terms (n) = 12

Last term (L) = 100

Common difference (d) = 3

First term (a) =?

We can obtain the first term of the arithmetic sequence as follow:

L = a + (n – 1)d

100 = a + (12 – 1)3

100 = a + (11)3

100 = a + 33

Collect like terms

100 – 33 = a

a = 67

Therefore, the first term of the arithmetic sequence is 67

Answer:

5935 base balls

Step-by-step explanation:

Volume of a cylinder : pi * r² * h

r = Radius, h = height = 6ft

Diameter = 4ft ; Radius = diameter / 2 = 4/2 = 2ft

V = π * 2^2 * 6

V = 75.398223 ft³

Diameter of baseball = 2.8 inches

2.8 inches = 2.8 × 2.8 * 2.8 = 21.952 in³ = 0.0127037 ft³

Hence,

75.398223 ft³ / 0.0127037ft³

= 5935.1370

= 5935 base balls

Answer: 2192.08

Step-by-step explanation:

6/100=0.06

1 - 0.06= 0.94

1 + 0.06= 1.06

2200*094*1.06= 2192.08

The value of the stock at the end of the second day is $2192.08.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

Value of stock = $2200

At the end of the first day →

6% decrement

6$ of 2200 ⇒ 2200 × 6/100 = 132

So,

2200 - 132 = $2068

At the end of the second day →

6% increment

6$ of 2068⇒ 2068× 6/100 = 124.08

So,

2068 +  124.08= $$2192.08

Hence "The value of the stock at the end of the second day is $2192.08".

Answer:

1.225 × 10 to the power 5 + 3.655 × 10³ = 1.26155 x 10 to the power 5

Step-by-step explanation:

Standard Notation:

122500 + 3655 = 1.26155 x 10 to the power 5

Scientific Notation:

1.225 × 10 to the power 5 + 3.655 × 10³ = 1.26155 x 10 to the power 5

E Notation:

1.225e5 + 3.655e3 = 1.26155e5

Answer:

56

Step-by-step explanation: Use the values of a, b, and c to find the discriminant.

Answer:

[tex]\Delta =56[/tex]

Step-by-step explanation:

We are given:

[tex]y = x^2 - 8x + 2[/tex][tex]y=x^2-8x+2[/tex]

So, a = 1, b = -8, and c = 2.

The discriminant (symbolized by Δ) is given by:

[tex]\Delta =b^2-4ac[/tex]

So, our discriminant in this case will be:

[tex]\Delta=(-8)^2-4(1)(2)=64-8=56[/tex]

Since our discriminant is a positive value, our equation has two real roots.

Answer:

Step-by-step explanation:

Answer:

a) 95% of people has an IQ score between 76 and 124​.

b) 0.3% of people has an IQ score less than 64 or greater than 136​.

c) 0.15% of people has an IQ score greater than 136

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 100

Standard deviation = 12

​(a) What percentage of people has an IQ score between 76 and 124​? ​

76 = 100 - 2*12

124 = 100 + 2*12

So within 2 standard deviations of the mean, and the percentage is 95%.

(b) What percentage of people has an IQ score less than 64 or greater than 136​?

64 = 100 - 3*12

136 = 100 + 3*12

99.7% of people has scores between 64 and 136. So 100 - 99.7 = 0.3% of people has an IQ score less than 64 or greater than 136​.

​(c) What percentage of people has an IQ score greater than 136​?

0.3% of people has an IQ score less than 64 or greater than 136​.

Since the normal distribution is symmetric, 0.3%/2 = 0.15% are below 64 are 0.15% are above 136.

Answer:

75,323,600

10.4%

292

4471

77

$2.54

Step-by-step explanation:

1. Voters in 2020 =

1.292 x 58,300,000 = 75,323,600

2.( number of turkey sandwich / total number of sandwich ) x 100

(51/491) x 100 = 10.4%

3. percent of chemistry majors = (number of chemistry majors / total students that graduated) x 100

0.017 = number of chemistry majors / 17,190

Multiply both sides of the equation by 17,190

17,190  x 0.017 = 292

4.  number of trees in 4 square miles = (4 x 1006) / 0.9 = 4471

5.  Percent from Canada = percentage of people from Canada x total number of people attending the conference

0.089 x 870 = 77

6. Average price =  total cost of items / total quantity sold

[(24 x 3.50) + (61 x0.25) + (18 x 9)] / 103 = 2.54

[tex] \sin(2x + 5) [/tex]

Let y = sin(z) . Where z = 2x +5

[tex]y = \sin(z) \\ z = 2x + 5[/tex]

Find the the derivatives

[tex] \frac{dy}{dx} = \cos(z) [/tex]

[tex] \frac{dz}{dx} = 2[/tex]

Multiply

[tex] \frac{dy}{dx} = \cos(z) \times 2 \\ = 2 \cos(z) [/tex]

Remember that z = 2x+5

Answer:

The answer is below.

Step-by-step explanation:

A square is a quadrilateral (has four sides and four angles) in which all the sides are equal. Also all the angle of a square are equal and measure 90°. The diagonals of a square are equal.

In square ABCD:

AB = BC = CD = AC

Given that  P, Q are the midpoints of BC, CD respectively. If AP = a and AQ = b.

a) In triangle ABP:

BC = AB (all sides of a triangle are equal)

BP = 1/2 (BC) = 1/2(AB) = 0.5AB

Using Pythagoras theorem:

AB² + BP² = AP²

substituting:

AB² + (0.5AB)² = a²

AB² + 0.25AB² = a²

1.25AB² = a²

AB² = a² / 1.25

AB² = 0.8a²

AB = √(0.8a²)

AB = a√0.8

b) In triangle ADQ:

AD = CD (all sides of a triangle are equal)

DQ = 1/2 (CD) = 1/2(AD) = 0.5AD

Using Pythagoras theorem:

AD² + DQ² = AQ²

substituting:

AD² + (0.5AD)² = b²

AD² + 0.25AD² = b²

1.25AD² = b²

AD² = b² / 1.25

AD² = 0.8b²

AD = √(0.8b²)

AD = b√0.8

c) In triangle ABD, Using Pythagoras theorem:

AB² + AD² = BD²

Substituting:

0.8a² + 0.8b² = BD²

But AB = AD (all sides of a triangle are equal). Hence AB = AD = 0.8a² = 0.8b²

BD = √(0.8a² + 0.8b²)

BD = √(1.6a²)     0.8a² = 0.8b²

BD = a√1.6

D) AC = AD (diagonal are equal)

AC = √(0.8a² + 0.8b²)

AC = √(1.6b²)     0.8a² = 0.8b²

AC = b√1.6

Answer:

[tex]\sqrt{61}[/tex] units

Step-by-step explanation:

We are given that

[tex]P_1=(-2,5)[/tex]

[tex]P_2=(4,0)[/tex]

We have to find the distance d (P1, P2) between the points P, and P2

We know that

Distance between  two points (x1,y1) and (x2,y2)  i

=[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using the formula

The distance d (P1, P2) between the points P, and P2

=[tex]\sqrt{(4-(-2))^2+(0-5)^2}[/tex]

The distance d (P1, P2) between the points P, and P2

[tex]=\sqrt{(4+2)^2+(-5)^2}[/tex]

The distance d (P1, P2) between the points P, and P2

=[tex]\sqrt{6^2+25}[/tex]

The distance d (P1, P2) between the points P, and P2

=[tex]\sqrt{61}[/tex] units

Answer:

Most likely answers are either 6 or 8.

Step-by-step explanation:

The sequence could be of all even numbers, so 2, 4, 6, 8, etc.

Or of all powers of 2, starting at 2, so 2, 4, 8, 16, etc.

Since there are an infinite number of sequences that fit the pattern, you just have to choose the most likely.
