The equation of a line in the form y is y = 150 - 85x.
This equation can be used to determine the amount of money in the grocery account at any given week, x. To solve, we will use the information given in the question.
We know that the initial amount in the account is $150. This is the y-intercept of the line. Therefore, 150 = 150 - 85x. Solving this equation for x, we get x = 0. This means that at week 0 the account has a balance of $150.
Next, we know that money is withdrawn from the account every week. We can use this information to solve for the slope of the line. We know that every week $85 is withdrawn from the account, so the slope of the line is -85. Therefore, the equation of the line is y = 150 - 85x.
Using this equation, we can determine the amount in the account at any given week. For example, at week 5, y = 150 - 85(5) = $25. This means that the account has a balance of $25 at week 5.

Answer:no
Step-by-step explanation:
a standard interior staircase has steps each with a rise (height) of 22 cm and a run (horizontal depth) of 23 cm. research suggests that the stairs would be safer for descent if the run were, instead, 28 cm. for a particular staircase of total height 4.57 m, how much farther into the room would the staircase extend if this change in run were made?
The staircase would extend 104.3cm farther into the room if the run were made 28cm instead of 23cm.
To find out how much farther into the room the staircase would extend if the run were 28 cm instead of 23 cm, we need to calculate the difference in the run and then multiply it by the number of steps.
The difference in the run is 28cm - 23cm = 5cm
To find the number of steps, we need to divide the total height of the staircase by the height of each step:
4.57m / 0.22m = 20.86 steps.
So the difference in the run multiplied by the number of steps is:
5cm * 20.86 steps = 104.3cm.
Therefore, the staircase would extend 104.3cm farther into the room if the run were made 28cm instead of 23cm.

So on solving provided question we can say that given angle is m/ABD (7q-46) (3q+6)° = m/ABD = 98
what are angles?An angle is a form in Euclidean geometry made composed of two rays, called the angle's sides, that meet at a point in the middle known as the angle's vertex. In the plane where the rays are placed, two rays can produce an angle. An angle is also produced when two planes intersect. They're known as dihedral angles. In plane geometry, an angle is the form that two rays or lines with a common termination might take. The Latin word "angulus," which means "horn," is where the English word "angle" comes from. The two rays, also known as the sides of the angle, have a common termination known as the vertex.

Factorise 6-y^2
Please help
Answer:
6-y^2 can be factored by using the difference of squares formula which states that:
a^2 - b^2 = (a+b)(a-b)
We can factorize 6-y^2 by using the following:
6 - y^2 = (sqrt(6) + sqrt(-y^2))(sqrt(6) - sqrt(-y^2))
= (sqrt(6) + yi)(sqrt(6) - yi)
where i is the imaginary unit.
So, 6-y^2 = (sqrt(6) + yi)(sqrt(6) - yi) is the factored form of 6-y^2
Please note that the factorization is only true for real values of y, when y is not real the expression can't be factorized.

The probability that B will equal 40, where random variable B represent the number in the sample who have a bachelor’s degree is 1.1340323e-12, that is 1.1340323 × 10⁻¹².
The question is asking for the probability that B, the number of residents in the sample of 50 who have a bachelor's degree, will equal 40. To calculate this probability, we need to use the binomial probability formula, which is:
P(B = x) = (n choose x) × pˣ × (1-p)⁽ⁿ⁻ˣ⁾
where:
n = sample size (50)
p = probability of success (31%)
x = number of successes (40)
So, the probability that B will equal 40 is:
P(B = 40) = (50 choose 40) × (0.31)⁴⁰ × (0.69)⁽⁵⁰ ⁻ ⁴⁰⁾
P(B = 40) = 1.1340323e-12

Answer: To determine if there is evidence to suggest that the proportion of individuals who caught pertussis and were not up to date on their booster shot is higher than those that were, we can conduct a two-sample proportion test.
The null hypothesis is that the proportion of individuals who caught pertussis and were not up to date on their booster shot is the same as the proportion of individuals who caught pertussis and were up to date on their booster shot.
H0: p1 = p2
The alternative hypothesis is that the proportion of individuals who caught pertussis and were not up to date on their booster shot is higher than the proportion of individuals who caught pertussis and were up to date on their booster shot.
Ha: p1 > p2
Using a two-sample proportion test with a significance level of 0.05, we can calculate the test statistic and p-value.
p1 = 15/132 = 0.1136
p2 = 11/368 = 0.0301
p = (15 + 11)/(132 + 368) = 0.0564
SE = sqrt{p(1-p)((1/132)+(1/368))} = 0.0165
z = (p1 - p2) / SE = 4.0491
p-value = P(z > 4.0491) = 0.0000
Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is evidence to suggest that the proportion of individuals who caught pertussis and were not up to date on their booster shot is higher than those that were.

To find the maximum height the ball achieves before landing, we need to find the vertex of the parabola represented by the equation h(t) = -16t^2 + 59.2t + 114.24. The vertex form of a parabola's equation is y = a(x-h)² + k where (h, k) is the coordinates of the vertex.
We can get the vertex form by completing the square of x term.
h(t) = -16t² + 59.2t + 114.24
h(t) = -16(t² - 3.68t) + 114.24 + 3.68t
h(t) = -16(t-0.92)² + 118.92

The respective probabilities are -
(a).P(vet concludes-no virus ,if no chicken is infected)=0.988,
(b).P(vet cincludes virus,if no chicken is infected)= 0.012,
(c).P(vet cincludes virus, if every chicken is infected)=0.99 ,
(d).P(vet cincludes virus, if 20% chickens are infected)= 0.383.
This problem involves the probability of binomial distribution as there are only two outcomes of the event, either the bird is infected or its not infected.
Now, let us suppose in this problem, that x is a random variable indicating the no. of chickens infected.
According to question , P(false positive test)=0.05,
P(false negative test)=0.10 where false positive test means that the bird is not infected and still the vet says that its infected.
false negative test means that the bird is not infected and the vet declares it to be infected.
Now, P(bird is not infected) = 1- P(bird tested false positive) = 1-0.05=0.95
Similarly, P(bird is infected) = 1 - P(bird tested false negative) 1- 0.10=0.90
Now, in the question , the vet declares the flock as infected if at least 3 out of 10 chickens are infected.
So, in (a) , t]if the vet does not declare the birds as infected means less than 3 birds would only be infected.
so, P(vet declares as uninfected) = P(x=0) + P(x=1) + P(x=2)=
10C0 (0.05)^0 (0.95^10) + 10C1 (0.05)^1 (0.95)^9 + 10C2(0.05)^2 (0.95)^8
Upon calculating this , we get 0.988.
Now, for (b) , P(no virus and vet declares it to be present)= 1- P(no virus and vet does not declare it to be infected)= 1-0.988 = 0.012.
(c) - the probability that every chicken in the flock is infected with the h6n2 virus, what is the probability that the veterinarian will conclude that the h6n2 virus is present in the flock = 1- P(every chicken is infected and the vet declares as not infected) = 1- bin (10,0.9,2)
=1- 10C0(0.9)^0(0.1)^10 + 10C1(0.9)^1(0.1)^9 + 10C2(0.9)^8(0.1)^2 = 1- 0.001 = 0.99.
(d) . Now here, we need to calculate P(x>=3) =
1- [10C0(0.22)^0(0.78)^10 + 10C1(0.22)^1(0.78)^9 + 10C2(0.22)^8(0.78)^2]
=0.383.
So, in this way we get answers as (a)-0.988 , (b)- 0.012, (c)-0.99 , (d) - 0.383.

find the diameter of each circle. use 3.14 for the value of pi. round your answer to the nearest tenth. circumference = 69.1 yd
please hurry
The diameter of a circle with a circumference of 69.1 yds is 22.
What is circumference of a circle?
The measurement of the circle's perimeter, also known as the circle's boundary, is called its circumference . The radius of the circle is considered when applying the formula to determine the circumference of the circle.
Circumference of circle(C) = 2πR
where,
R represents the radius of the circle
We know that diameter of circle is twice of its radius i.e
Diameter(D) = 2R
Thus, C = πD
We are given Circumference(C) = 69.1yd and π= 3.14
So, using C = πD, we get
⇒69.1 = 3.14*D
⇒D = 69.1/3.14
⇒D = 22
Hence, the diameter of a circle with a circumference of 69.1 yds is 22.

The system of equations below has no solution.
StartLayout enlarged left-brace 1st row two-thirds x + five-halves y = 15 2nd row 4 x + 15 y = 12
An equation that could represent a linear combination of the given system of equations is: B. 0 = -78.
What is no solution?In Mathematics, no solution is also referred to as zero solution, and an equation is said to have no solution when the left hand side and right hand side of the equation are not the same or equal.
Generally speaking, a linear combination of any system of equations can be obtained by either adding or subtracting a multiple of the equations of the system.
2x/3 + 5y/2 = 15 ......equation 1.
4x + 15y = 12 ......equation 2.
By multiplying equation 1 with 6 and equation with 1, we have the following system of equations:
4x + 15y = 90 ......equation 3.
4x + 15y = 12 ......equation 4.
By subtracting equation 3 from equation 4, we have the following:
0 = -78
In this context, we can reasonably infer and logically conclude that 0 = -78 is an equation that would most likely represent a linear combination of the given system of equations.
