Answer:

x = 11, y = 17

Step-by-step explanation:

Set the equations equal to each other. Since the vertical angles are congruent, 8x + 7 = 9x - 4 and 5y = 7y - 34. Now, solve your equations for the x and y values.

8x + 7 = 9x - 4

x = 11

5y = 7y - 34

2y = 34

y = 17

A ratio shows us the number of times a number contains another number. The number of players in group 2 is 12.

A ratio shows us the number of times a number contains another number.

Given that the coach wants the ratio of the players in group 1 to players in group 2 to be 3. Therefore, the ratio can be written as,

Number of players in group1/Number of players in group2 = 3/1

Multiply the numerator and the denominator of the ratio by x,

Number of players in group1/Number of players in group2 = 3x /1x

Now, the total number of players can be written as,

3x + x = 48

4x = 48

x = 48/4

x = 12

Further, the number of players in group 2 can be written as,

Number of players in group2 = x = 12

Hence, the number of players in group 2 is 12.

D. f(x)  divided by (x−1)  has a remainder of 0.

C. (x−1)  is a factor of  f(x) .

Step-by-step explanation:

Just took a test with this question these are the answers!

The statements that are true about the polynomial function are;

Given the polynomial function [tex]f(x)=x^3-x^2-4x+4[/tex]

If x = -1, hence;

[tex]f(-1)=(-1)^3-(-1)^2-4(-1)+4\\f(-1)=-1-1+4+4\\f(-1)=-2+8\\f(-1) =6[/tex]

This shows that f(x) ≠ 0 when x = −1 .

To check if x - 1 is a factor, we will substitute x = 1 into the function and check if the result is zero as shown:

[tex]f(1)=1^3-1^2-4(1)+4\\f(1)=1-1-4+4\\f(1) =0[/tex]

Answer:

Yes there is a significant difference in the standard deviations of the two sets of measurements made by the two instruments at the 95%

[tex]F_{calc} = 8.3457[/tex]

Step-by-step explanation:

From the question we are told that

    The  normal bicarbonate level is  k  =  23-29 mmol/L

    The number of times the blood was tested is  n =  6

    The mean concentration for old instrument is  [tex]\= x_1 = 24.6\ mmol/L[/tex]

     The  standard deviation is  [tex]\sigma_1 = 1.56\ mmol/L[/tex]

    The mean concentration for the new instrument is  [tex]\= x_2 = 25.9 mmol/L[/tex]

    The standard deviation is [tex]\sigma_2 = 0.54 mmol/L[/tex]

     The confidence level is  95%

     The level of significance is mathematically represented  as  [tex]\alpha = (100 - 95)\%[/tex]

[tex]\alpha = 0.05[/tex]

 Generally the test statistics is mathematically represented as

      [tex]F_{calc} = \frac{\sigma_1 ^2}{\sigma_2^2}[/tex]

=>    [tex]F_{calc} = \frac{1.56^2}{0.54^2}[/tex]

=>    [tex]F_{calc} = 8.3457[/tex]

Generally  the degree of freedom for the old instrument is  is mathematically evaluated as  

     [tex]df = n -1[/tex]

=>  [tex]df = 6 -1[/tex]  

=>   [tex]df = 5[/tex]  

Generally  the degree of freedom for the new instrument is  is mathematically evaluated as  

     [tex]df_1 = n -1[/tex]

=>  [tex]df_1 = 6 -1[/tex]  

=>   [tex]df_1 = 5[/tex]  

For  the f distribution table  the critical value  of  [tex]\alpha[/tex] at df  and [tex]df_1[/tex] is  

    [tex]F_{tab} =5.0503[/tex]

Generally given that the [tex]F_{calc} > F_{tab}[/tex] it means that  there is a significant difference in the standard deviations of the two sets of measurements made by the two instruments at the 95%

5). Reason for the congruence is given as SSS.

   "Property SSS for the congruence of two triangles states that all three sides of the triangles must be congruent."

In the given triangles ΔMLN and ΔULN,

ML ≅ LU [given]

NL ≅ NL [Reflexive property]

To fulfill SSS property third sides of the given triangles should be given as congruent.

Therefore, additional information required will be MN ≅ NU

6). SAS property of congruence states that "two sides and included angle between these sides of two triangles must be congruent"

From the given triangles ΔPWS and ΔVXW,

PW ≅ VW [Given]

∠PWS ≅ ∠XWV [Vertically opposite angles]

Therefore, to fulfill the property of SAS additional information required will be,

SW ≅ WV

Answer:

one way.

k=y2-y1 / x2-x1

40.96 mm

3.2(10) = 32; 3.2 cm → 32 mm

each side of scale drawing is 32 mm

2(10) = 20; 2 cm → 20 mm

scale is 4 mm to 20 mm

[tex]\frac{4}{20}= \frac{x}{32}[/tex]

cross-multiply:

32(4) = 128

128 / 20 = 6.4

each side of the actual drawing is 6.4 mm.

6.4 * 6.4 = 40.96

40.96 mm

40.96 mm

What is scaling ?

It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.

It is given that the scaling of drawing is 4mm to 2cm of actual drawing and the scaled drawing side of square earring is 3.2cm.

Now, corelating the scale given which means for 1mm of actual side of earring the drawing scale is 0.5 cm or 5mm. Therefore, for having 3.2 cm of side of earring in drawing let [tex]x[/tex] be the actual side this is calculated below :

                                                [tex]\begin{aligned}20 \text{mm}&\rightarrow 4\text{mm}\\32\text{mm}&\rightarrow x\text{\:mm}\\\frac{4}{20}&=\frac{x}{32}\\x&=6.4 \text{mm}\end{aligned}[/tex]

Now, the actual side of earring is 6.4 mm therefore, the area of the front of earring will be : 6.4 mm x 6.4 mm =40.96 mm
