Answer:

The 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 is (-8.04, 0.84).

Step-by-step explanation:

The (1 - α)% confidence interval for the difference between population means is:

[tex]CI=(\bar x_{1}-\bar x_{2})\pm z_{\alpha/2}\times \sqrt{\frac{\sigma^{2}_{1}}{n_{1}}+\frac{\sigma^{2}_{2}}{n_{2}}}[/tex]

The information provided is as follows:

[tex]n_{1}= 138\\n_{2}=156\\\bar x_{1}=61\\\bar x_{2}=64.6\\\sigma_{1}=18.53\\\sigma_{2}=13.43[/tex]

The critical value of z for 98% confidence level is,

[tex]z_{\alpha/2}=z_{0.02/2}=2.326[/tex]

Compute the 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 as follows:

[tex]CI=(\bar x_{1}-\bar x_{2})\pm z_{\alpha/2}\times \sqrt{\frac{\sigma^{2}_{1}}{n_{1}}+\frac{\sigma^{2}_{2}}{n_{2}}}[/tex]

     [tex]=(61-64.6)\pm 2.326\times\sqrt{\frac{(18.53)^{2}}{138}+\frac{(13.43)^{2}}{156}}\\\\=-3.6\pm 4.4404\\\\=(-8.0404, 0.8404)\\\\\approx (-8.04, 0.84)[/tex]

Thus, the 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 is (-8.04, 0.84).

Answer:

the answer should be < .

Answer:

(A) x= -4

Step-by-step explanation:

The question requires you to find the equation of the line parallel to x=7

Line x=7 is a vertical line crossing the x-axis at x=7

A vertical line has undefined slope, no slope

However, parallel lines are those that do not meet and has the same slope. This means you should expect that the equation required should also have an undefined slope, slope of zero.

The line will pass through point (-4,1) and be a vertical line.

The equation of the line will be: x= -4

Answer:

The least value of perimeter is:

[tex]Perimeter = 26m[/tex]

The greatest value is:

[tex]Perimeter = 86m[/tex]

Step-by-step explanation:

Given

Shape: Rectangle

[tex]Area = 42m^2[/tex]

Required

Determine the least and greatest possible Perimeters

Area is calculated as:

[tex]Length * Width = Area[/tex]

So; first, we need to determine the factors of the given Area;

[tex]Length * Width = Area[/tex]

[tex]1 * 42 = 42[/tex]

[tex]2 * 21 = 42[/tex]

[tex]3 * 14 = 42[/tex]

[tex]6 * 7 = 42[/tex]

Perimeter is then calculated as:

[tex]Perimeter = 2 * (Length + Width)[/tex]

When Area is:

[tex]1 * 42 = 42[/tex]

[tex]Perimeter = 2 * (1 + 42)[/tex]

[tex]Perimeter = 2 * 43[/tex]

[tex]Perimeter = 86m[/tex]

When Area is:

[tex]2 * 21 = 42[/tex]

[tex]Perimeter = 2 * (2 + 21)[/tex]

[tex]Perimeter = 2 * 23[/tex]

[tex]Perimeter = 46m[/tex]

When Area is:

[tex]3 * 14 = 42[/tex]

[tex]Perimeter = 2 * (3 + 14)[/tex]

[tex]Perimeter = 2 * 17[/tex]

[tex]Perimeter = 34[/tex]

When Area is:

[tex]6 * 7 = 42[/tex]

[tex]Perimeter = 2 * (6 + 7)[/tex]

[tex]Perimeter = 2 * 13[/tex]

[tex]Perimeter = 26m[/tex]

Comparing the above.

The least value of perimeter is:

[tex]Perimeter = 26m[/tex]

The greatest value is:

[tex]Perimeter = 86m[/tex]

Answer:

110 degrees

Step-by-step explanation:

it is 110 degrees because on a line comebinedt is 180 degrees. And you already ahve one side which is 70 degrees. So 180 minus 70 is 110 degrees.

Answer:

m5 would be 110 degrees

Step-by-step explanation:

so basically all you have to do for that problem is subtract 70 from 180

Answer:

The answer is 7

Answer:

The maximum number of guests for $780 would be 26.

Step-by-step explanation:

Write and solve an equation of ratios.  In the first column write $630/$780; in the right column write 21/x:

 630         21

---------- = -------

  780         x

Cross-multiplying, we get 630x = 21(780), which yields x = 26.

The maximum number of guests for $780 would be 26.

Answer:

m∠1 = 62°

m∠2 = 45°

m∠3 = 24°

Step-by-step explanation:

The measure of the exterior angle of a triangle is equal to the sum of the remote interior angles.

The measure of angles ∠1, ∠2 and ∠3 are 62°, 45° and 24° respectively.

From the given figure, measure of angles are 118°, 73° and 49°.

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

From the given figure, 118° + ∠1 = 180°

⇒ ∠1 = 180° - 118°

⇒ ∠1 = 62°

Now, 118° = 73° + ∠2

⇒ ∠2 = 118° - 73°

⇒ ∠2 = 45°

Using angle sum property of a triangle

62° + 49° + (∠2+∠3) = 180°

⇒ 111° + (∠2+∠3) = 180°

⇒ (∠2+∠3) = 180°- 111°

⇒ (∠2+∠3) = 69°

⇒ 45° +∠3 = 69°

⇒ ∠3 = 24°

Therefore, the measure of angles ∠1, ∠2 and ∠3 are 62°, 45° and 24° respectively.

Answer:

26, -0.85, 17

Step-by-step explanation:

hi! so for 14, you can plug in -11 for every x in the equation.

f(-11)= 15-(-11)

=15+11

=26

your answer is 26.

for 15, we can plug in 0.3 for x.

g(0.3)=-2.5(0.3)-0.1

= -0.75-0.1

= -0.85

your answer is -0.85.

for 16, you can plug in -17 for x.

f(-17)= -(-17)

=17

your answer is 17.

Answer:

14:   26

15: -8.5

16:  17

Step-by-step explanation:

The f(x) basically gives you what x is, as the inside of parenthesis means the value of x. You then can plug in x into the equation for each of the equations. Whenever you get something like 24- (-42) The negatives cancel out and you add the two values together instead.

Answer:c

Step-by-step explanation:

100° is a possible measure for m∠Y.

Hence, Option C is the correct option.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that,

In triangles ΔXYZ and ΔMPN

XY = MP and YZ = PN

XY=23 in. and MN=19 in.

Clearly

XY > MN

⇒ m ∠Y > m ∠P ...( since angle opposite to the greater side is greater )

And m ∠P = 85° ⇒ m ∠Y > 85°

Hence,

option (1) and option (2) are not correct as they are less than 85°.

Option 4 is also not correct as it cannot be possible in a triangle because 180° is the angle of a straight line.

Therefore, Option 3 should be the correct option correct option, 100° is a possible measure for m ∠Y.

Answer:

[tex]300\; \rm lb[/tex].

Step-by-step explanation:

Let [tex]x[/tex] represent the mass (in pounds) of that [tex]15\%[/tex] copper alloy required, such that the final mixture would contain [tex]25.5\%[/tex] copper by mass.

Consider: if [tex]x[/tex] pounds of that [tex]15\%[/tex] copper alloy is mixed with [tex]700[/tex] pounds that [tex]30\%[/tex] copper alloy, what would be the mass of copper in the mixture?

Therefore, the mixture would contain [tex](210 + 0.15\, x) \; \rm lb[/tex] of copper.

The mass of that mixture would be [tex](700 + x)\; \rm lb[/tex]. The mass fraction of copper in that mixture would be:

[tex]\displaystyle \frac{(210 + 0.15\, x)\; \rm lb}{(700 + x)\; \rm lb} \times 100\%[/tex].

This ratio is supposed to be equal to [tex]25.5\%[/tex]. These two pieces of equations combine to give an equation about [tex]x[/tex]:

[tex]\displaystyle \frac{(210 + 0.15\, x)\; \rm lb}{(700 + x)\; \rm lb} \times 100\% = 25.5\%[/tex].

[tex]\displaystyle \frac{210 + 0.15\, x}{700 + x} = 0.255[/tex].

Simplify and solve for [tex]x[/tex]:

[tex]210 + 0.15\, x= 0.255\, (700 + x)[/tex].

[tex](0.255 - 0.15)\, x= 210 - 0.255 \times 700[/tex].

[tex]\displaystyle x = \frac{210 - 0.255 \times 700}{0.255 - 0.15} = 300[/tex].

Therefore, [tex]300\; \rm lb[/tex] of that [tex]15\%[/tex] alloy would be required.

Answer:

She misinterpreted the 4 and 0 in both of their batting averages.

Answer:

a) SS, Ss, ss

b) 1/4

c) 1/2

Step-by-step explanation:

According to this question, a gene coding for possession or not of sickle cell has two alleles. Allele "S" codes for normal cell while allele "s" codes for sickle cell. A heterozygous individual or carrier will have a "Ss" genotype.

If two carriers of the sickle cell condition decide to have a child and mate i.e. Ss × Ss, the following gametes will be produced by each parent: S and s.

a) Using these gametes (S, s) in a punnet square (see attached image), the four possible offsprings with the following genotypes will be produced: SS, Ss and ss in a GENOTYPIC RATIO 1:2:1.

b) Since offsprings with the genotype "ss" will possess the sickle cell condition/phenotype, the probability of offsprings that will have sickle cell is 1/4 i.e. 1 out of 4 possible offsprings

c) Also,carrier genotype will be "Ss", therefore, the probability that the offspring will not have sickle cell but still be a carrier (one normal cell allele and one sickle cell allele) will be 2/4 or 1/2 i.e. 1 out of 2 possible offsprings.
