Step-by-step explanation:

The value of missing length x in the congruent triangles is determined as 3.6.

option D.

The length of segment x is calculated by applying congruency theorem as follows;

Consider triangle ABC,

AQ/AT = AB / AC

The given parameters include;

length AQ = 5

length AT = 6

length AB = 5 + 3  = 8

length AC = 6 + x

The value of missing length x is calculated as follows;

5/6 = 8/(6 + x )

5(6 + x) = 6(8)

30 + 5x = 48

5x = 48 - 30

5x = 18

x = 18/5

x = 3.6

Answer:

163

Step-by-step explanation:

What's great about these problems is that when there is a line that is divided by another line, causing 2 angles, the 2 angles must equal 180 degrees.  That means the 163-degree angle + either the x or the z angle would equal 180 degrees.  The second best part about this is that if it is separated how yours is, with 2 lines, opposite angles are equal.  That means that angle x and angle z are equal, as well as the 163 angle is equal to the y angle.  Hope this helps with more than just this problem!

Answer:The 99% confidence interval is

To find the 99% confidence interval for the mean systolic blood pressure (SBP) level, we use the formula:

CONFIDENCE INTERVAL = Mean ± Z * (Standard Deviation / √n)

Where:

Mean is the sample mean of SBP

Z is the Z-score corresponding to the desired confidence level

Standard Deviation is the population standard deviation

Explanation:

Given that the sample size is 13 and the standard deviation is 10, we need to calculate the sample mean and the Z-score for the 99% confidence level.

First, we calculate the sample mean:

Mean = (129 + 134 + 142 + 114 + 120 + 116 + 133 + 142 + 138 + 148 + 129 + 133 + 140) / 13

= 1724 / 13

≈ 132.62

Next, we need to determine the Z-score for a 99% confidence level. The Z-score can be found using a Z-table or a statistical calculator. For a 99% confidence level, the Z-score is approximately 2.576.

Now, we can calculate the confidence interval:

Confidence Interval = 132.62 ± 2.576 * (10 / √13)

132.62 ± 2.576 * (10 / 3.6056)

≈ 132.62 ± 2.576 * 2.771

≈ 132.62 ± 7.147

Therefore, the 99% confidence interval for the mean SBP level is approximately (125.47, 139.77).

When you write your measurement as the mean ± standard deviation, it means that you are displaying how far the data is spread out from the mean value. A normal distribution is one that is symmetrical and bell-shaped, where most of the data lies near the mean value.

When you write your measurement as the mean ± standard deviation, it means that you are displaying how far the data is spread out from the mean value. In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. When you add the standard deviation to the mean and also subtract the standard deviation from the mean, you get the upper and lower bounds of the range that contains about 68% of the data. This range is called one standard deviation.The value of the standard deviation indicates how much the data varies around the mean. If the standard deviation is high, then the data is widely spread out and vice versa. Additionally, when you write a measurement as the mean ± standard deviation, it is assumed that the data is normally distributed. A normal distribution is one that is symmetrical and bell-shaped, where most of the data lies near the mean value.

The elimination method involves manipulating these equations to eliminate one of the variables. This is done by multiplying one or both of the equations by a constant so that the coefficients of one of the variables are equal in both equations, but with opposite signs. The equations are then added or subtracted, depending on the signs, to eliminate one of the variables.

Let x be the cost of one adult ticket and y be the cost of one child ticket.

From the given information, we can write two equations:

2x + 2y = 38 (equation 1)

2x + 5y = 59 (equation 2)

To solve for x and y, we can use elimination method.

Multiplying equation 1 by 5 and equation 2 by 2, we get:

10x + 10y = 190

4x + 10y = 118

Subtracting equation 2 from equation 1, we get:

6x = 72

x = 12

Substituting x = 12 into equation 1, we get:

2(12) + 2y = 38

2y = 14

y = 7

Therefore, one adult ticket costs £12 and one child ticket costs £7.

a) 6 adult tickets and 6 child tickets:

Cost = 6(£12) + 6(£7) = £102

b) 4 adult tickets and 7 child tickets:

Cost = 4(£12) + 7(£7) = £77

c) 3 child tickets:

Cost = 3(£7) = £21

To determine if the polynomial is even, odd, or neither, we substitute -x for x in the polynomial and simplify. -3(-x)² + 6(-x) = -3x² - 6x. Since the polynomial is not equal to its negation, it is neither even nor odd.

To write the equation of the line with an x-intercept at -6 and a y-intercept at 2, we can use the slope-intercept form of a line, y = mx + b, where m is the slope and b is the y-intercept.

In this case, the y-intercept is given as 2, so the equation becomes y = mx + 2. To find the slope, we can use the formula (y2 - y1) / (x2 - x1) with the given points (-6, 0) and (0, 2). We find that the slope is 1/3. Thus, the equation of the line is y = (1/3)x + 2.

For the polynomial f(x) = -3x² + 6x, the degree is 2 and the leading coefficient is -3. The end behavior of the graph is determined by the degree and leading coefficient. Since the leading coefficient is negative, the graph will be "downward" or "concave down" as x approaches positive or negative infinity.

To find the zeros, we set the polynomial equal to zero and solve for x. -3x² + 6x = 0. Factoring out x, we get x(-3x + 6) = 0. This gives us two solutions: x = 0 and x = 2.

The x-intercept is the point where the graph intersects the x-axis, and since it occurs when y = 0, we substitute y = 0 into the polynomial and solve for x. -3x² + 6x = 0. Factoring out x, we get x(-3x + 6) = 0. This gives us two x-intercepts: (0, 0) and (2, 0).

To determine if the polynomial is even, odd, or neither, we substitute -x for x in the polynomial and simplify. -3(-x)² + 6(-x) = -3x² - 6x. Since the polynomial is not equal to its negation, it is neither even nor odd.

The attenuated oral poliovirus vaccine (OPV) is no longer administered in the U.S.A. due to its potential to be spread to contacts and occasionally cause poliomyelitis.

The decision to discontinue the use of the attenuated oral poliovirus vaccine (OPV) in the U.S.A. was primarily based on concerns regarding its safety and efficacy. While the OPV was effective in providing immunity against poliovirus, it had some drawbacks that led to its discontinuation.

One of the major concerns with OPV was its ability to be spread to contacts. OPV contains live but weakened poliovirus strains, which can be shed in the stool of vaccinated individuals. In rare cases, these weakened strains can revert to a virulent form and cause poliomyelitis in contacts who come into contact with the virus through contaminated feces.

Additionally, the OPV has a small risk of causing poliomyelitis itself, although this risk is extremely rare. The weakened strains in the vaccine have a very low potential to cause disease, but in rare instances, they can regain their ability to cause paralysis.

To address these concerns, countries like the U.S.A. have shifted to using the inactivated poliovirus vaccine (IPV), which does not carry the risk of vaccine-derived poliovirus cases or transmission to contacts. IPV is a safer alternative that provides effective protection against poliovirus without the potential risks associated with OPV.

Fred Meyer's unit Rate: $2.17 per pound.

Costco's unit Rate: $2.10 per pound.

Better Price:​  Costco has the better price for cheddar cheese.

To determine who has the better price for cheddar cheese, let's calculate the unit rate for both Fred Meyer and Costco.

Fred Meyer:

Cheddar cheese is priced at $6.50 for 3 pounds. To find the unit rate, we divide the price by the quantity: $6.50 ÷ 3 pounds = $2.17 per pound.

Costco:

Costco offers 10 pounds of cheddar cheese for $21. To find the unit rate, we divide the price by the quantity: $21 ÷ 10 pounds = $2.10 per pound.

Comparing the unit rates, we can see that Fred Meyer's cheddar cheese is priced at $2.17 per pound, while Costco's cheddar cheese is priced at $2.10 per pound.

Therefore, based on the unit rates, Costco has the better price for cheddar cheese. They offer it at a slightly lower price per pound compared to Fred Meyer. Customers can save $0.07 per pound by purchasing cheddar cheese from Costco instead of Fred Meyer.

However, it's important to note that price isn't the only factor to consider when deciding where to purchase cheddar cheese. Other factors such as location, quality, convenience, and personal preferences should also be taken into account.

Additionally, it's always a good idea to compare prices and consider any ongoing promotions or discounts that might affect the final decision.
