In psychological theory, there are 66 types of basic instincts in a human being, and personality is determined by the presence or absence (2(2 choices) of these 66 basic instincts. How many different types of personalities can be identified
Answer:
2145
Step-by-step explanation:
Given that:
Number of basic instincts present = 66
Number of choices = 2
Using combination :
nCr = n! / (n - r)! r!
66C2 = 66! / (66 - 2)!2!
66C2 = 66! / 64!2!
66C2 = (66 * 65) / 2
66C2 = 2145 different personalities

If a factory can produce 250 desks in 5 days, how many desks will it produce in 15 days?
Answer:
750 would be ur answer
Step-by-step explanation:
happy new year!
Answer:750 desks
Step-by-step explanation: I would start by setting up an equation. 5d=250 (d means days). Then, to isolate the d, I would divide both sides of the equation by 5. I would get d=50. So there are 50 desks made daily. To find out the number of desks made in 15 days, I would just multiply both sides of the equation d=50 by 15 and I would get 15d=750. That means, there are 750 desks produced in 15 days. I hope this helps you out a bit!
During second period, Kiera completed a grammar worksheet. Of the 90 questions, she got 70% right. How many questions did Kiera get right?
Answer:
we conclude that Kiera got the right 63 questions.
Step-by-step explanation:
Total questions = 90
The percentage of correct question = 70%
Using the formula
The number of correct questions = 70% of 90
= [70/100] × 90
= 0.7 × 90
= 63
Therefore, we conclude that Kiera got the right 63 questions.

Answer:
y = \frac{4}{5}x + \frac{32}{5}
Step-by-step explanation:
(x₁ , y₁) = (-3, 4) & (x₂ , y₂) = (2 , 8)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]= \frac{8-4}{2-[-3]}\\\\= \frac{8-4}{2+3}\\\\= \frac{4}{5}[/tex]
m = 4/5 ;
Equation of the line: y - y₁ = m(x - x₁)
[tex]y - 4 = \frac{4}{5}(x - [-3])\\\\y - 4 = \frac{4}{5}(x +3)\\\\y - 4 = \frac{4}{5}x + \frac{4}{5}*3\\\\ y = \frac{4}{5}x + \frac{12}{5}+4\\\\ y = \frac{4}{5}x + \frac{12}{5} + \frac{4*5}{1*5}\\\\ y =\frac{4}{5}x + \frac{12}{5} +\frac{20}{5}\\\\ y = \frac{4}{5}x + \frac{32}{5}[/tex]

H = -16t^2 + 84t + 100 what is maxium height
Answer:
[tex]H=210.25\ \text{units}[/tex]
Step-by-step explanation:
Given that,
[tex]H = -16t^2 + 84t + 100[/tex] ...(1)
We need to find the maximum height
For maximum height, put dH/dt = 0
[tex]\dfrac{d(-16t^2 + 84t + 100)}{dt}=0\\\\-32t+84=0\\\\t=\dfrac{84}{32}\\\\t=2.625\ s[/tex]
Put t = 2.625 in equation (1)
[tex]H = -16(2.625)^2 + 84(2.625) + 100\\\\=210.25\ \text{units}[/tex]
Hence, the maximum height [tex]=210.25\ \text{units}[/tex]

Algebra...George bought 2 identical couches and 3 identical chairs. A couch cost twice as much as a chair. He spent $270 more on th ecouches than on the chairs. How much did he spend altogether
Answer:
$1890
Step-by-step explanation:
x= couches
y=chair.
x=2y
2x=3y+270
2(2y) or 4y=3y+270
y=270
x=540
2(540)+3(270)=1890.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
George bought 2 identical couches and 3 identical chairs.
A couch costs twice as much as a chair.
Let the cost of one couch = 2x
Let the cost of one chair = x
Now,
He spent $270 more on the couches than on the chairs.
This means that,
2(2x) = 270 + 3x
4x = 270 + 3x
Subtract x on both sides.
x = 270
The total spending.
= 4x + 3x
= 4 x 270 + 3 x 270
= 1080 + 810
= $1890
Thus,
The total spending is $1890

Jodie spent 25% less buying her English reading books thank Claudia. .Gianna spent 9% less than Claudia. Gianna spent more than Jodie by what percent? If your using decimal round to the nearest tenth
Answer:
21.3%
Step-by-step explanation:
Given that:
Money spent by Jodie for buying English reading books = 25% lesser than that of Claudia
and
Money spent by Gianna is 9% lesser than that of Claudia.
To find:
By what percent, Gianna spent more than Jodie ?
Solution:
Let the money spent by Claudia on her English books = 100
Now, as per question statement:
Money spent by Jodie = 100 - [tex]\frac{9}{100}\times 100[/tex] = 75
Money spent by Gianna = 100 - [tex]\frac{25}{100}\times 100[/tex] = 91
Now, to find the answer:
[tex]\dfrac{\text{Difference between money spent by Gianna and Jodie}}{\text{Money spent by Jodie}}\times 100[/tex]
[tex]\Rightarrow \dfrac{91-75}{75}\times 100\\\Rightarrow \dfrac{16}{75}\times 100\\\Rightarrow \bold{21.3\%}[/tex]
Therefore, Gianna spent 21.3% more than the amount that was spent by Jodie.

Complete Question
Three dressers are placed side by side. One dresser is 3 feet 9 inches wide, another is 3 feet 3 inches wide, and the third is 5 feet 11 inches wide. How wide are they combined? Write your answer in feet and inches. Use a number less than for inches
Answer:
12 feet 11 inches
Step-by-step explanation:
To solve the above question, we would have to add up all the width of thee dressers together.
Hence:
3 feet 9 inches + 3 feet 3 inches + 5 feet 11 inches
= (3 feet + 3 feet + 5 feet) + (9 inches + 3 inches + 11 inches)
= 11 feet +( 23 inches)
Note that
12 inches = 1 feet
Hence:
11 feet (23 inches/12 inches)
11 feet (1 feet + 11 inches)
= 12 feet 11 inches.
Therefore, the width of the 3 dressers combined = 12 feet 11 inches

Answer:
Colin will have to wait for 2 hours for the pond to completely empty
Step-by-step explanation:
Volume of a Prism
The volume of a prism of base area Ab and height H is computed with the formula:
V=Ab.H
We are given a pond in the shape of a prism with a trapezoidal base (front view).
The area of a trapezoid of bases b1 and b2, and height a, is given by:
[tex]\displaystyle A_b=\frac{b_1+b_2}{2}.a[/tex]
The parallel bases of the trapezoid have measures of b1=0.6 m and b2=1.4 m, and the height is a=2 m, thus the area is:
[tex]\displaystyle A_b=\frac{0.6+1.4}{2}*2[/tex]
[tex]A_b=2\ m^2[/tex]
The height of the prism is H=1m, thus the volume of the pond is:
[tex]V=2\ m^2*1\ m[/tex]
[tex]V=2\ m^3[/tex]
It's also known the level of the pond goes down by 20 cm (0.2 m) in the first 30 minutes. Note at this moment the level is still at the rectangular prism zone of the pond, thus the volume of water is calculated as the area of the face of water by the height it went down:
[tex]V_w=1\ m*2\ m*0.2\ m = 0.4\ m^3[/tex]
The pond still has this volume of water:
[tex]V_p=2\ m^3-0.4\ m^3=1.6\ m^3[/tex]
The pond was drained [tex]0.4\ m^3[/tex] in 30 minutes, thus the rest of the water will be taken out in
[tex]\frac{1.6}{0.4}*30 =120\ min[/tex]
Thus, Colin will have to wait for 2 hours for the pond to completely empty
