A car travels at a constant speed.
What is the car's speed between checkpoints, expressed as a unit rate?
Use the information given in the picture.
Answer:
Step-by-step explanation:
Checkpoint A-> time being 1:00pm total miles driven being 120 and
checkpoint B-> time being 3:00pm and the total miles being 208
The distance between two checkpoint A and B is 208 - 120 = 88 miles
Now the time between the two checkpoints = 3.00 - 1.00 = 2 hours
We need to find car speed between the checkpoints
We know Distance = speed * time
Speed = 44 miles per hour
Answer:
The answer is 1 miles
Step-by-step explanation:
1+1=2

A cylindrical mass has a radius of 5 cm and a height of 6 cm. If the mass of the cylinder is 900 grams, what is the density of the cylinder?
Approximately 1.9 grams per cubic centimeter.
First you calculate the size of the cylinder in centimeters by taking the area of the base and multiplying it by the height, and then you divide the mass of the cylinder by the volume.
Here is a number in expanded form. (6 x 100) + (1 x 10) + (7 x 1) + (9 x 1/10) + (2 x 1/1000) Write it in standard form. (Using Decimals)
Answer:
617.902
Step-by-step explanation:
(6 * 100) + (1 * 10) + (7 * 1) + (9 *1/10) + (2 *1/1000)=308951/500
308951/500=617.902
The standard form of given number is 6.17 ×10².
What is standard form?
Standard form is a way of writing down in easy form of very large or very small numbers.
Let E is the standard form of given number
E = (6 × 100) + (1 × 10) + (7 × 1) + (9 ×1/10) + (2 ×1/1000)
E =600+10+7+0.9+0.002
E =617.902
E =0.617 × 10³ = 6.17 ×10²
E = 6.17 ×10²
Hence, the standard form of given number is 6.17 ×10²

In a large human population, cranial length is approximately normally distributed with a mean of 185.6 mm and a standard deviation of 12.7 mm. What is the probability that a random sample of size 10 from this population will have a mean less than than 180? a. 0.0174 b. 0.1357 c. 0.0823 d. -1.39
Answer:
The correct option is c
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 185.6 \ mm[/tex]
The standard deviation is [tex]\sigma = 12.7 \ mm[/tex]
The sample size is n = 10
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_{x} = \frac{\sigma}{\sqrt{n} }[/tex]
=> [tex]\sigma_{x} = \frac{ 12.7}{\sqrt{ 10 } }[/tex]
=> [tex]\sigma_{x} = 4.016[/tex]
Generally the probability that a random sample of size 10 from this population will have a mean less than than 180 is mathematically represented as
[tex]P(X < 180 ) = P(\frac{ X - \mu }{\sigma_{x} } < \frac{180 - 185.6}{4.016} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X < 180 ) = P(Z < - 1.394 )[/tex]
From the z table the area under the normal curve to the left corresponding to -1.394 is
[tex]P(X < 180 ) = P(Z < - 1.394 ) = 0.081659[/tex]
=> [tex]P(X < 180 ) = 0.0823[/tex]

Answer:
155
Step-by-step explanation:
- because of the angle rules, (6x+1) = (2x+17)
- with this, you can now solve to get x = 4
- also because of the angle rules, y = 180 - (2x+17)
- replace the x with 4 and calculate and you'll get y = 155

What is the distance between z1 = 5 - 2i and z2 = 8 + i?
3√2
13.3
2√3
18
Answer:
d=2√10
Step-by-step explanation:
The distance between the two points will be given by:
d=√[(x-x1)^2+(y-y1)^2]
point z1=(3-2i) has the coordinates of (3,-2)
point z2=(5-8i) has the coordinates of (5,-8)
thus the distance between them will be:
d=√[(-8-(-2)²+(5-3)²)]
d=√[(-6)²+2²]
d=√(36+4)
d=√40
d=2√10
Answer:
3√2
Step-by-step explanation:
distance formula: d = √(a₁ - a₂)² + (b₁ - b₂)²
a = x, b = y
d = √(x₁ - x₂)² + (y₁ - y₂)²
