The model represents an inequality. what is the solution set for the inequality?
Answer:
Then the solution set is all the values of x equal to or larger than -3.
Step-by-step explanation:
First, we know that each long strip represents an x.
Each white square represents 1.
Each grey square represents -1
Then, at the left side, we have:
8 long stripes.
12 white squares
Then we can write that as:
8*x + 12*1 ≥
And in the right side, we have 12 grey squares, then that is:
≥ 12*-1 = -12
Then the inequality is:
8*x + 12 ≥ -12
To find the solution set, we just need to isolate x.
First, we can subtract 12 in both sides to get:
8*x + 12 - 12 ≥ -12 - 12
8*x ≥ -24
Now we can divide both sides by 8
8*x/8 ≥ -24/8
x ≥ -3
Then the solution set is all the values of x equal to or larger than -3.

Answer:
34
Step-by-step explanation:
1. look at XV, and see that it equals 32 altogether.
WX is doubled the amount of WV. So it would be the same pattern on the other side.
2. 17*2=34
You might notice that 17-9=8, so wouldn't 34-16 be 8 as well. Nope, it would be doubled just like WX is doubled the amount of WV.

The midpoint of UV is M(3, 2). One endpoint is U(1, 3). Find the coordinates of the other
endpoint V.
Write the coordinates as decimals or integers.
Answer:
V(5, 1)
Step-by-step explanation:
Given:
M(3, 2)
U(1, 3)
From midpoint to U:
(x, y) → (x - 2, y + 1)
To get from midpoint to V, we inverse the formula:
(x, y) → (x - 2, y + 1)
(x, y) → (x + 2, y - 1)
To find V:
(x, y) → (x + 2, y - 1)
(3, 2) → (3 + 2, 2 - 1)
(3, 2) → (5, 1)

Answer:
Step-by-step explanation:
4(x-3)^2 = 80
4x-12^2= 80 --- (distribute)
4x+144= 80 --- ( why a positive 144 because a (-) * a (-) = a (+)
4x = (80-144) --- ( subtract -144 from +144(do it on both sides)
4x = -64 --- (divide both sides by 4)
x= -16
Answer:
2√5 +3
Step-by-step explanation:
Isolate x:
4(x-3)^2 = 80
Divide both sides by 4.
(x-3)^2 = 20
Then take the square root of each side.
(x-3) = √20
Add 3 to each side.
x = √20 + 3
√20 can be rewritten as 2√5.
x = 2√5 + 3
Write an exponential function y = a(b)" whose graph passes through the given
points,
(-1,2),(2,54)
Answer:
y = 6 * 3ˣ
Step-by-step explanation:
y = a * bˣ
(-1 , 2): 2 = a * (b)⁻¹ = a/b a = 2b
(2 , 54) 54 = a * b² = 2b * b² = 2b³
b³ = 54/2 = 27 b = 3
a = 6
Function: y = 6 * 3ˣ
The equation of a parabola is y=x2–8x+14. Write the equation in vertex form.
Answer:
Step-by-step explanation:
y=x^2-8x+14
To write in vertex form, group the two x-terms to make a complete square, adjust the constant term accordingly
y = x^2-8x+16 -2
factor the first three terms on the right hand side
y = (x-4)^2 -2
This means that the vertex is at x-4 = 0, or x=4, and y=2.
Tina's yard is 679ft by 2828ft. If each measurement is rounded to the nearest hundred, what is the area of Tina's yard?
Answer:
1,960,000 square feet
Step-by-step explanation:
First let's round 679 to the nearest hundred. To do this we look at the 10s digit. If it is 5 or greater, we round up to 700 (because it is past halfway between 600 and 700), and is not we round down back to 600.
The 10s digit of 679 is 7, which is greater than 5. Therefore 679 rounded to the nearest hundred is 700.
Now let's look at 2828. The 10s digit here is 2, which is smaller than 5, therefore we round back down to 2800, which is closer than 2900.
Now we have 700 and 2800. To find the area, (assuming the yard is a rectangle) we multiply the length by the width together (these two values). 700x2800 = 1,960,000 square feet.

A store manager claims that 60% of shoppers who enter her store make a purchase. To investigate this claim, she selects a random sample of 40 customers and finds that 40% of them make a purchase. She wants to know if the data provide convincing evidence that the true proportion of all customers who enter her store that will make a purchase differs from 60%. The P-value of this test is 0.0098. Interpret the P-value.
Assuming the true population proportion of shoppers who will make a purchase is 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.
Assuming the true population proportion of shoppers who will make a purchase differs from 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.
Assuming the true population proportion of shoppers who will make a purchase is 0.60, the probability of obtaining a sample statistic as extreme as or more extreme than 0.40 in a random sample of 40 customers is 0.0098.
Assuming the true population proportion of shoppers who will make a purchase is different from 0.60, the probability of obtaining a sample statistic as extreme as or more extreme than 0.40 in a random sample of 40 customers is 0.0098.
Answer:
I do believe that it is Option B
(Assuming the true population proportion of shoppers who will make a purchase differs from 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.)
Step-by-step explanation:
This sample provide evidence that the grocery store manager overstated the true proportion P-value = 0.0333.
What is p-value?In null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct.
here, we have,
Given data in the question:
To test whether population proportion p is overstated;
Null hypothesis H₀ : p = (75%) = 0.75
Alternative hypothesis H₁ : = < (75%) < 0.75
Now, sample proportion p" = 64 / 100 = 0.64
From the dot plot below,
we will determine the p-value for test { P(p" < 0.64)}
The number of times p"<0.64 in 150 simulations is 5
Therefore:
P(p" < 0.64 ) = 5 / 150 = 0.0333
P-value = 0.0333
At 5% level of significance;
0.0333 < 0.05
Therefore, we reject null hypothesis H₀ at 5% level of significance,

A grocery store manager claims that 75% of shoppers purchase bananas as least once a month. Technology was used to simulate choosing 150 SRSs of size n = 100 from a population of shoppers where 75% buy bananas. The dotplot shows pˆ = the sample proportion of shoppers who bought bananas in the past month. A random sample of 100 shoppers from the store were selected and 64 bought bananas in the past month. Does this sample provide evidence that the grocery store manager overstated the true proportion? Justify your answer.

The probability of getting a marble marked with a number greater than 4 is [tex]\frac{1}{9}[/tex].
What is probability?Probability is the measure of happening or non-happening of outcomes of random experiment.
Probability formulaP(E) = Number of favorable outcomes/Total number of outcomes
where,
P(E) is the probability of an event.
According to the given question.
Total number of marbles in jar = 18
⇒ Total number of outcomes = 18
( 6 red marbles, 6 black marbles, and 6 green marbles)
But it is given that, black or red marble is randomly selected.
Therefore, the total number of outcomes reduced to 12.
Numbers which are greater than 4 among 1 to 6 are 5 and 6.
Total number of numbers which are greater than 4 in jar = 2 × 3 =6
But we have to select only black or red marble.
Therefore,
Total number of favorable outcomes = 4
The probability of selecting a marble greater than 4 which are red
= [tex]\frac{4}{12} =\frac{1}{3}[/tex]
The probability of selecting a marble greater than 4 which are black
= [tex]\frac{4}{12} = \frac{1}{3}[/tex]
Therefore, the probability of getting a marble marked with a number greater than 4 [tex]=(\frac{1}{3}) (\frac{1}{3} )=\frac{1}{9}[/tex]
Hence, the probability of getting a marble marked with a number greater than 4 is [tex]\frac{1}{9}[/tex].
