Answer:
9
Step-by-step explanation:
Given that
Spending done by Miranda each time while go to the store = $7
Spending done by Savannah each time while go to the store = $9
For computing the least possible number we need to take the least common multiple of $7 and $9 i.e to be $63
Now the lease possible number for Miranda has been to the store is
[tex]= \frac{ Lease\ common\ multiple}{Spending\ done \ by\ miranda}[/tex]
[tex]= \frac{\$63}{\$7}[/tex]
= 9
Or we can do one thing as we know that 7 is a prime number which is not cut by any other number except one while the 9 factor could be [tex]= 3\times 3[/tex]
Therefore the 9 times would be considered
Which is greater or less then 2/3 Or 1 3/4

Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m?
-15m = -4m
-7m - 8 = m - 4
-3m - 8 = 4 - m
m - 4 = -7m - 8
-8 - 7m = -4 + m
-8 - 3m = 4 - m
Step-by-step explanation:
-2m - 5m - 8 = 3 - 7 + m
Solving like terms
-7m - 8 = - 4 + m
Rearranging
-7m - 8 = m - 4
Shantanu bought more apples than bananas, and he bought more bananas than cantaloupes. Let a represent the number of apples Shantanu bought, let b represent the number of bananas, and let c represent the number of cantaloupes. Let's compare the expressions b+c and a. Which statement is correct?
Answer:
There is not enough information to tell
Step-by-step explanation:
We are given that:
a>b
b>c
Therefore:
a>c
However, we are not given enough information to draw a relationship between b+c and a.
In order to better understand this situation, try applying values. Let a=4, b=2, and c=1.
In this case, a > b+c. However if a = 9, b=8 and c=7, then a < b+c.
In both stipulated cases, the given conditions are met, but no conclusion can be reached regarding the relationship between b+c and a.

4
10, m, start superscript, 4, end superscript?
Answer:
2mStep-by-step explanation:
Given the functions 8m², 4m and 10m⁴, in order to find the greatest common factor, we will find a factor common to all the functions as shown;
8m² = 2*2*(2*m)*m
4m = 2*(2*m)
10m⁴ = (2*m)*5*m³
from the three expansion, it ca be seen that only 2 and m are common to all the function as shown in parentheses.
The greatest common factor factor will be the product of 2 and m i.e 2*m = 2m

I pretty sure the answer is Nervous
nervous, because it sends signals to your brain and it’s basically the main thing that makes you move.
for example, when the oven is hot you can feel the heat and notice how you don’t touch it, that’s because your brain knows that if you touch the oven you’re going to burn yourself and your brain stops you from touching the surface of the oven.
Mr. Maxwell White bought a house at the cost of GHȼ250,000,000.00. He paid 20% of the cost out of his own resources an took a loan for the remaining amount at 2 1/2 % simple interest per annum. Calculate the total amount Mr. Maxwell White paid for the house, if he paid the loan 8 years later.
Answer:GHȼ290,000,000
Step-by-step explanation:
Given the following :
Cost of house = 250,000,000
Amount paid out of his own resources = 20% of house cost
Amount loaned = 250,000,000 - (20% of 250,000,000)
Rate = 2 1/2% = 5/2% = 0.025
Period or time = 8 years
Therefore,
Amount paid out of his own resources :
0.2 × 250,000,000 = 50,000,000
Amount loaned = (250,000,000 - 50,000,000) = 200,000,000 = principal
Simple Interest on loan = (principal × rate × time)
200,000,000 × 0.025 × 8 = 40,000,000
Total amount paid back= (200,000,000 + 40,000,000) = 240,000,000
Total amount paid for the house :
Total loan paid + amount paid from own resource:
240,000,000 + 50,000,000 = 290,000,000

A quadrilateral is circumscribed around a circle. The sum of the lengths of two of its opposite sides is 15 cm. Find the perimeter of the quadrilateral.
Answer:
The perimeter of the quadrilateral is 30 cm.
Step-by-step explanation:
To circumscribe implies drawing a required figure around a given figure, while to inscribe means drawing a required figure inside a given figure. From the question, the quadrilateral is circumscribed around the circle.
And given that the sum of the lengths of its two opposite sides is 15 cm.
The perimeter of a figure is the sum of the length of the sides of the figure. For this quadrilateral, the sum of opposite sides are equal.Thus;
Perimeter of the quadrilateral = 2(l+b)
= (l + b) + (l + b)
= 15 + 15
= 30
The perimeter of the quadrilateral is 30 cm.
A scientist is measuring the temperature change in a decimal compound. The temperature dropped 11 f per hour from the original temperature. After four hours the temperature was 90 f find the compounds original temperature.
Answer:
[tex] F = mt +b[/tex]
From the info given we know that m =-11 and we have a condition given:
[tex] F =90 , t =4[/tex]
Using this condition we have:
[tex] 90 = -11*4 +b[/tex]
And solving for b we got:
[tex] 90 +4*11 = 90 +44= 134[/tex]
So then the original temperatue for this case is 134 F
Step-by-step explanation:
For this case we know that after four hours the temperature was 90 f and the temperature dropped 11 f per hour.
We can use a linear model to solve the problem given by:
[tex] F = mt +b[/tex]
Where F represent the temperature, t the time in hours and m the slope and b the intercept.
From the info given we know that m =-11 and we have a condition given:
[tex] F =90 , t =4[/tex]
Using this condition we have:
[tex] 90 = -11*4 +b[/tex]
And solving for b we got:
[tex] 90 +4*11 = 90 +44= 134[/tex]
So then the original temperatue for this case is 134 F
What is the best next step in the constructed of a line that passes through point C and is parallel to AB? (Assume that the arc drawn with the compass placed at point A was the result of the last step performed.)
Answer:
B
Step-by-step explanation:
using the same compass setting, place the point of the compass at C and draw an arc that intersects ĀB
B. using the same compass setting, place the point of the compass at C and draw an arc that intersects ĀB
Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.
So, the next step should be using the same compass setting, place the point of the compass at C and draw an arc that intersects ĀB.
Therefore the correct option is C.

Rewrite the equation by completing the square.
x^2+ 12x + 36 = 0
Answer:
(x+6)^2 =0
Step-by-step explanation:
x^2+ 12x + 36 = 0
Subtract 36 from each side
x^2+ 12x + 36-36 = 0-36
x^2 +12x = -36
Take the coefficient of x
12
Divide by 2
12/2 =6
Square it
6^2 =36
Add this to each side
x^2+ 12x + 36 = -36+36
(x+12/2)^2 = 0
(x+6)^2 =0
The given quadratic equation [tex]x^2+ 12x + 36 = 0[/tex] is written in squaring form as [tex](x + 6)^2 = 0[/tex].
Used the concept of a quadratic equation that states,
An algebraic equation with the second degree of the variable is called a Quadratic equation.
Given that the equation is,
[tex]x^2+ 12x + 36 = 0[/tex]
Now completing the square as

In a study done in Miami's economically disadvantaged community, it was determined that 38 out of 62 children who attended preschool needed social services later in life compared to 49 out 61 children who did not attend preschool. Test the claim that the proportion of children who need social services later in life is greater amongst the children who did not attend preschool compare to the ones who did attend preschool. Use a 0.05 level of significance.
Answer:
Step-by-step explanation:
This is a test of 2 population proportions. Let 1 and 2 be the subscript for the children who attended preschool and need social services later in life and children who did not attend preschool and need social services later in life. The population proportion for the children who attended preschool and children who did not attend preschool would be p1 and p2 respectively.
p1 - p2 = difference in the proportion of proportion of the children who attended preschool and children who did not attend preschool .
The null hypothesis is
H0 : p1 = p2
p1 - p2 = 0
The alternative hypothesis is
Ha : p1 < p2
p1 - p2 < 0
it is a left tailed test
Sample proportion = x/n
Where
x represents number of success(number of complaints)
n represents number of samples
For children who attended preschool,
x1 = 38
n1 = 62
p1 = 38/62 = 0.61
For children who did not attend preschool,
x2 = 49
n2 = 61
p2 = 49/61 = 0.8
The pooled proportion, pc is
pc = (x1 + x2)/(n1 + n2)
pc = (38 + 49)/(62 + 61) = 0.71
1 - pc = 1 - 0.71 = 0.29
z = (p1 - p2)/√pc(1 - pc)(1/n1 + 1/n2)
z = (0.61 - 0.8)/√(0.71)(0.29)(1/62 + 1/61) = - 0.19/0.08183139728
z = - 2.32
Since it is a left tailed test, we would determine the probability for the area below the z score from the normal distribution table. Therefore,
p = 0.01
Since alpha, 0.05 > than the p value, 0.01, then we would reject the null hypothesis. Therefore, At a 5% level of significance, the the proportion of children who need social services later in life is greater amongst the children who did not attend preschool compare to the ones who did attend preschool.

Doroteo determined that the correlation coefficient for a set of data was -.9 what percent of the total variation in the Y values is not explained by the regression line
Answer: 10%
Step-by-step explanation:
(1 - 0.9) × 100 = 10%
With a correlation Coefficient of -0.9. This signifies a strong negative correlation between the x and y variables. That is an increase in the x variable leads to a corresponding decrease in the y variable and vice versa. The correlation Coefficient could also be interpreted to mean that about 90% of the variation in the y variable is explained by the regression line or equation. With the the remaining 10% being unexplained. This is why a correlation Coefficient of 1 or - 1 refers to a perfect relationship, meaning 100% variation in y is explained by the regression line.
