Answer:

Triangle JKL is congruent to triangle

✔ ABC

.

Side LK corresponds to sides

✔ WV and CB

.

Angle JLK corresponds to angles

✔ UWV and ACB

.

Step-by-step explanation:

just did it on edge 2020

Triangle JKL is congruent to triangle ABC.

Side LK corresponds to sides BC.

Angle JLK corresponds to angles BAC.

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

As per the given information,

ΔJKL ≅ ΔUVW: This means that triangle JKL is congruent to triangle UVW. Congruent triangles have the same shape and size, so their corresponding angles and sides are equal in measure and length, respectively.

ΔUVW ≅ ΔABC: This means that triangle UVW is congruent to triangle ABC.

Combining these two pieces of information, we can conclude that:

ΔJKL ≅ ΔABC: This is because if two triangles are congruent to the same triangle, then they must be congruent to each other. Therefore, triangle JKL is congruent to triangle ABC.

Side LK corresponds to sides BC: Corresponding sides of congruent triangles are equal in length. In this case, side LK corresponds to side VW (since JKL ≅ UVW), which corresponds to side BC (since UVW ≅ ABC).

Angle JLK corresponds to angles BAC: Corresponding angles of congruent triangles are equal in measure. In this case, angle JLK corresponds to angle UVW (since JKL ≅ UVW), which corresponds to angle BAC (since UVW ≅ ABC).

So, we can say that triangle JKL is congruent to triangle ABC, side LK corresponds to sides BC, and angle JLK corresponds to angles BAC.

Answer:

40 cans weigh over 14.7 ounces

Step-by-step explanation:

Given

Mean = 14 ounces

SD = 0.7

We have to find the z-score for 14.7 first

[tex]z = \frac{14.7-14}{0.7}\\z = \frac{0.7}{0.7} = 1[/tex]

As we have to find the number of cans greater than 14.7, forst we will find the area to the left of obtained z-score and then subtract from 1.

So,

P(z<1) = 0.8413

Now,

P(z>1) = 1 - P(z<1) = 1-0.8413 = 0.1587

As the total number of cans is 250,

The cans which weigh over 14.7 are:

= 0.1587 * 250

= 39.675

Rounding off to nearest whole number

40 cans

Hence,

40 cans weigh over 14.7 ounces

Answer:

40 cans

Answer:

x=−4+√22 or x=−4−√22

Step-by-step explanation:

Substitute all values in the quadratic formula.

Solve.

Answer:

[tex]\boxed {\sf x= {{ - 4\pm \sqrt{22} }}}[/tex]

Step-by-step explanation:

The quadratic equation is used to find the roots of a quadratic. The formula is:

[tex]x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}[/tex]

when  [tex]{ax^2 + bx + c = 0}[/tex]

We are given the quadratic: [tex]x^2+8x-6=0[/tex]

If we compare the given quadratic to the standard form of a quadratic, then:

[tex]a= 1\\b=8 \\c= -6[/tex]

Substitute the values into the formula.

[tex]x = \frac{{ - 8\pm \sqrt {8^2 - 4(1)(-6)} }}{{2(1)}}[/tex]

Solve inside the radical first.

Solve the exponent.

[tex]x = \frac{{ - 8\pm \sqrt {64 - 4(1)(-6)} }}{{2(1)}}[/tex]

Multiply 4, 1, and -6.

[tex]x = \frac{{ - 8\pm \sqrt {64 - -24}}}{{2(1)}}[/tex]

Add 64 and 24 (2 negative signs become a positive)

[tex]x = \frac{{ - 8\pm \sqrt {88}}}{{2(1)}}[/tex]

Solve the denominator.

[tex]x = \frac{{ - 8\pm \sqrt {88}}}{{2}}[/tex]

The radical can be simplified. 88 is divisible by a perfect square: 4

[tex]x= \frac{{ - 8\pm \sqrt {4}\sqrt{22} }}{{2}}[/tex]

Take the square root of 4.

[tex]x= \frac{{ - 8\pm 2\sqrt{22} }}{{2}}[/tex]

Divide by 2.

[tex]x= {{ - 4\pm \sqrt{22} }}[/tex]

The roots are: x=0.690416  and x=−8.69042

The correlation Coefficient gives the measure of the strength and direction of the relationship between two variables. - 0.833 depicts a strong negative relationship. Hence, one can be confident that the predicted value will be close to the actual Value.

The Correlation Coefficient, R ranges from - 1 to 1, with values closer to - 1 and 1 representing strong negative and positive relationship respectively, which is only achieved of the data is modeled very well.

Therefore, since, - 0.833 is a strong correlation Coefficient, then we can be confident in the predicted value.

Answer: you have to divide

Step-by-step explanation:

Answer:

We can think in the area as:

A rectangle of 100m by 64m

And two half circles (o a whole circle if we combine them) of diameter = 64m

Then we need to calculate the area of these two figures and then sum them.

The area of a rectangle of width W and length L is:

A = A*L

then the area of the rectangle will be:

A1 = 100m*64m = 6400m^2

The area of a circle of diameter d is:

A = pi*(d/2)^2

in this case, d = 64m

pi = 3.14

Then:

A2 =  3.14*(64m/2)^2 = 3215.35m^2

The total area of the field is:

A = A1 + A2 = 6400m^2 + 3215.35m^2 = 9615.36 m^2

Now, we know that the cost per square meter is $5.00

Then the total cost will be:

Cost = A*$5.00/m^2 = 9615.36 m^2*$5.00/m^2 = $35215.36

area of rect. = 24

area of circle (half circle+half circle = full circle) = pi*r^2 = pi*(2*2) = pi*4 = about 12.57

2 = radius since 4 = diameter

24-12.57 = 11.43

Step-by-step explanation:

Cost ($) = C

lbs (Blueberries) = W

One pound of blueberries costs $2.75 because to find how much 1 lb is you need to divide by 6.

6 is the number of pounds at that point in the graph, so you divide both the pounds and cost by 6 to find how much 1 lb is.

To find how much 5 lbs costs, multiply both the cost and number of pounds ($2.75 to 1 lb) by 5.

2.75 * 5 is 13.75 (This means C is wrong)

Do the same but with 12 for D

2.75 * 12 is 33, so D is correct

You could do the same method as above for E, but the easier way to do this is to see that the relationship of 3:9 is equal to a 1:3 ratio, which is the same as what the pounds to cost ratio is (which is 1:2.75)

There are 4 lines between each number so each line would be 1/4

A is at -1 1/2

B is -3/4

C is 3/4

D is 1 3/4

Using the information given, it is found that:

a.

The standard error for the difference is of 0.0176.

The 95% confidence interval is 0.0151 to 0.0841.

b.

Since 0 is not part of the confidence interval, it is not plausible that there is no difference between males and females in the proportion who agree that each person has only one true love.

For males, we have that:

[tex]n = 1213, p_M = \frac{372}{1213} = 0.3067, s_M = \sqrt{\frac{0.3067(0.6933)}{1213}} = 0.01324[/tex]

For females, we have that:

[tex]n = 1412, p_F = \frac{363}{1412} = 0.2571, s_F = \sqrt{\frac{0.2571(0.7429)}{1412}} = 0.01163[/tex]

The distribution of differences has mean and standard error given by:

[tex]p = p_M - p_F = 0.3067 - 0.2571 = 0.0496[/tex]

[tex]s = \sqrt{s_M^2 + s_F^2} = \sqrt{0.01324^2 + 0.01163^2} = 0.0176[/tex]

It is given by:

[tex]p \pm zs[/tex]

z is the critical value, which considering that there is a 95% confidence level, it is of z = 1.96.

Then:

[tex]p - zs = 0.0496 - 1.96(0.0176) = 0.0151[/tex]

[tex]p + zs = 0.0496 + 1.96(0.0176) = 0.0841[/tex]

The 95% confidence interval is 0.0151 to 0.0841.

Item b:

Since 0 is not part of the confidence interval, it is not plausible that there is no difference between males and females in the proportion who agree that each person has only one true love.

Answer:

The graph of the line [tex]y=\frac{2}{3}x+3[/tex] that contains the point (-3,1) with a slope of 2/3 is attached below.

Step-by-step explanation:

We know that the slop-intercept form of the equation is

[tex]y=mx+b[/tex]

where m is the slope, and b is the y-intercept.

Given the slope = m = 2/3, and point (-3, 1)

[tex]1=\frac{2}{3}\left(-3\right)+b[/tex]

[tex]-\frac{2}{3}\cdot \:3+b=1[/tex]
