Use multiplication. 4 times what number is about 35? 35÷4
Answers
Answer:
Answer explained in picture (8.75)
So after doing the division and getting the answer we multiply 8.75 by 4 we will get 35
Using multiplication we get, 4 times 8.75 is about 35.
Here, we have,
given that,
4 times what number is about 35
now, let, the number be x.
so, we get,
4 times x is = 35
or, 4 × x = 35
or, x= 35/4
or, x = 35÷4
or, x = 8.75
Hence, Using multiplication we get, 4 times 8.75 is about 35.

Dalton built a linear model to show the height of a meteor falling to the Earth. The meteor starts at 100 km above the Earth's surface and falls at a rate of 20km per second. The x values represent the time in seconds and the y values represent the height of the meteor. What does the domain represent in context of the model?
Answers
Answer:
The domain represents the time of motion of the meteor as it falls from 100 km height above the Earth's surface at a speed of 20 km
Step-by-step explanation:
The given parameters from the question are;
The elevation of the meteor above the Earth's surface = 100 km
The rate at which the meteor falls = 20 km per second
The 'x' values represent the time in seconds and the 'y' values represent the meteor's height
Therefore, we have;
y = 100 - 20·x
The domain of a function is the set of inputs to the function
Therefore, the domain represent the time it takes the meteor to reach the given 100 km height above the Earth's surface
At the start x = 0 seconds
On the Earth's surface, y = 0, therefore;
0 = 100 - 20·x
x = 100/20 = 5
When the meteor just touches the Earth's surface x = 5 seconds
Therefore, the domain is 0 ≤ x ≤ 5.
Susie is looking for butterflies in an area where: 15% of the butterflies are of type A 30% of the butterflies are of type B 55% of the butterflies are of type C Suppose that she spots two butterflies on her walk, and that the types of the two butterflies are independent from each other (perhaps because they are spotted in different locations). (a) What is the probability that the two butterflies she spots will both be type A butterflies
Answers
Answer:
the probability that the two butterflies she spots will both be type A butterflies is 0.0044
Step-by-step explanation:
The computation of the probability that the two butterflies she spots will both be type A butterflies is shown below:
= 1 ÷ Type A × 1 ÷ Type A
= 1 ÷ 15 × 1 ÷ 15
= 1 ÷ 225
= 0.0044
Hence, the probability that the two butterflies she spots will both be type A butterflies is 0.0044

Answers
The formula for rectangle is 2L + 2W = P
If you know the perimeter of a square and rectangle are the same you can set the equations equal to each other.
So 2L + 2W = 4L and since you know the side measurements. You sub them in.

Polling organizations regularly collect data on the public’s opinions and habits. A question on a recent survey asked, “How often do you purchase coffee from a coffeehouse?” There may be differences in how people respond to this question based on whether the person is a full-time student. Suppose a polling organization uses random digit dialing of local phone numbers to take a poll and asks respondents whether they are full-time students. In addition, they ask respondents to identify how often they purchase coffee from a coffeehouse (never, once a week, two to three times a week, daily, more than once a day). The data are collected in a 5-by-2 table of counts. Which of the following is the appropriate null hypothesis when conducting a chi-square test for the data?
Answers
Answer:
there is an association between how often a person purchases coffee from a coffee house and whether a person is a full time student.
Step-by-step explanation:
Answer:
C) H0 : How often a person purchases coffee from a coffeehouse is not associated with whether a person is a full-time student.
Step-by-step explanation:
This represents a chi-square test for independence because one sample was taken and two variables were observed. This is an appropriate null hypothesis for a chi-square test for independence in this study as it hypothesizes no association between coffee-purchasing habits and full-time student status.

P(E) = Number of favorable outcomes / total number of outcomes

A model rocket is launched straight upward. The solid fuel propellant pushes the rocket off the ground at an initial velocity of 50 feet per second.
s(t)= -4t2 + 50t - 84. Show work to get credit
a. What is the maximum height reached by the rocket?
b. What time will it reach the maximum height?
c. You forgot to put the parachute in the rocket. When will the rocket hit the ground?
Answers
Answer:
a) 72.25sec
b) 6.25secs
c) after 10.5secs and 2 secs
Step-by-step explanation:
Given the height reached by the rocket expressed as;
s(t)= -4t^2 + 50t - 84
At maximum height, the velocity of the rocket is zero i.e ds/dt = 0
ds/dt = -8t + 50
0 = -8t + 50
8t = 50
t = 50/8
t = 6.25secs
Hence it will reach the maximum height after 6.25secs
To get the maximum height, you will substitute t - 6.25s into the given expression
s(t)= -4t^2 + 50t - 84
s(6.25) = -4(6.25)^2 + 50(6.25) - 84
s(6.25) = -156.25 + 312.5 - 84
s(6.25) = 72.25feet
Hence the maximum height reached by the rocket is 72.25feet
The rocket will reach the ground when s(t) = 0
Substitute into the expression
s(t)= -4t^2 + 50t - 84
0 = -4t^2 + 50t - 84
4t^2 - 50t + 84 = 0
2t^2 - 25t + 42 = 0
2t^2 - 4t - 21t + 42 = 0
2t(t-2)-21(t-2) = 0
(2t - 21) (t - 2) = 0
2t - 21 = 0 and t - 2 = 0
2t = 21 and t = 2
t = 10.5 and 2
Hence the time the rocket will reach the ground are after 10.5secs and 2 secs
