what number is exactly halfway between 2.5 and 3.5
Answer:
3 is exactly halfway between 2.5 and 3.5.
Step-by-step explanation:
The first number is 2.5
The second number is 3.5
We need to find the number that is exactly halfway between 2.5 and 3.5. It can be calculated as follows :
[tex]n=\dfrac{2.5+3.5}{2}\\\\n=\dfrac{6}{2}\\\\n=3[/tex]
Hence, 3 is exactly halfway between 2.5 and 3.5.

Answer:
[tex]x=7.8[/tex]
Step-by-step explanation:
In any right triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse.
The angle marked 33 degrees has its opposite side labelled with [tex]x[/tex] and the hypotenuse of the triangle labelled with 12.
Thus, we can set up the following equation to solve for [tex]x[/tex]:
[tex]\tan 33^{\circ}=\frac{x}{12},\\x=12\tan 33^{\circ}=7.79289111837\approx \boxed{7.8}[/tex]
Answer:
Step-by-step explanation:
tan(33°) = x/12
x = 12tan(33°) ≈ 7.79

there are 200 students attending the basketball game, based on the sample, how many of them are in seventh grade?
Answer:
76
Step-by-step explanation:
19 out of 50 are in 7th grade.
200/50 = 4
Multiply both numbers in the ratio by 4.
19 out of 50 = 76 out of 200
Answer: 76
A company hopes to improve customer satisfaction, setting a goal of less than 5% negative comments. A random survey of 850 customers found only 34 with complaints. Does this provide evidence at the 10% significance level that the company has reached its goal of decreasing the percentage of complaints
Answer:
The p-value of the test is 0.0901 < 0.1, which means that this provides evidence at the 10% significance level that the company has reached its goal of decreasing the percentage of complaints.
Step-by-step explanation:
A company hopes to improve customer satisfaction, setting a goal of less than 5% negative comments.
At the null hypothesis, we test if the proportion of negative comments is of at least 5%, that is:
[tex]H_0: p \geq 0.05[/tex]
At the alternative hypothesis, we test if this proportion is less than 0.05, that is:
[tex]H_1: p < 0.05[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.05 is tested at the null hypothesis:
This means that [tex]\mu = 0.05, \sigma = \sqrt{0.05*0.95}[/tex]
A random survey of 850 customers found only 34 with complaints.
This means that [tex]n = 850, X = \frac{34}{850} = 0.04[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.04 - 0.05}{\frac{\sqrt{0.05*0.95}}{\sqrt{850}}}[/tex]
[tex]z = -1.34[/tex]
P-value of the test and decision:
The p-value of the test is the probability of finding a sample proportion below 0.04, which is the p-value of z = -1.34.
Looking at the z-table, z = -1.34 has a p-value of 0.0901.
The p-value of the test is 0.0901 < 0.1, which means that this provides evidence at the 10% significance level that the company has reached its goal of decreasing the percentage of complaints.

1. Determine the length of JG using
circle D.
Show your work and write out your
justification.
Be prepared to answer questions
about additional angles, arcs and
segments from circle D.
Given:
In circle D, [tex]\angle EDH\cong \angle EDG[/tex].
To find:
The length of JG.
Solution:
We know that, if two central angles are congruent then the corresponding chords are congruent and their measures are equal.
We have,
[tex]\angle EDH\cong \angle EDG[/tex]
It means chords EH and EG are congruent and their measures are equal.
[tex]EH=EG[/tex]
[tex]9=EG[/tex]
Using segment addition property, we get
[tex]EJ+JG=EG[/tex]
[tex]4+JG=9[/tex]
[tex]JG=9-4[/tex]
[tex]JG=5[/tex]
Therefore, the length of JG is 5 units.
Answer:

Sadie and Connor both play soccer. Connor scored 2 times as many goals as Sadie. Together they scored 9 goals. Could Sadie have scored 4 goals? Why or why not?
Answer:
No.
Step-by-step explanation:
Sadie goals = s
that means
2s+ s = 9 (2s is Connor's goals. Twice Sadie's)
3s=9
s=3
Sadie scored 3 goals

Find the midpoint of the equation y = 4x - 6 between the x-intercepts and the y-intercepts.
Step-by-step explanation:
y int
x=0
y=4(0)-6
y=-6
0;-6
x int
y=0
0=4x-6
6=4x
6/4=x
3/2=x
3/2;0
Answer:
Below in bold.
Step-by-step explanation:
y = 4x - 6
Find y-intercept:
y = 4(0) - 6 = -6
Y intercept is at (0, -6)
x-intercept:
4x - 6 = 0
4x = 6
x = 6/4 =1.5.
x intercept is at (1.5, 0)
Midpoint is at ((0+1.5)/2, (-6 + 0)/2)
= (0.75, -3)

Step-by-step explanation:
Si compraste 0.5 mts. de alambre grueso con un costo de $ 4.00 pesos por metro y 0.4 mts. de alambre delgado con un costo de $5.00 pesos por metro,
¿Cuánto fue el costo total en la compra de los metros de alambre?
Answer:
El costo total en la compra es $4.00 pesos.
Step-by-step explanation:
El costo total en la compra de los metros de alambre viene dado por la suma de los costos de los metros individuales de los alambres gruesos y delgados:
[tex] C_{t} = C_{g} + C_{d} [/tex]
En donde:
[tex] C_{t} [/tex]: es el costo total
[tex] C_{g} [/tex]: es el costo del alambre grueso
[tex] C_{d} [/tex]: es el costo del alambre delgado
Podemos encontrar el costo de cada alambre multiplicando el valor por la cantidad de metros:
[tex]C_{g} = 0.5 m*\frac{\$ 4.00}{m} = \$2.00[/tex]
[tex]C_{d} = 0.4 m*\frac{\$ 5.00}{m} = \$2.00[/tex]
Entonces, el costo total es:
[tex]C_{t} = 2.00 + 2.00 = \$4.00[/tex]
Por lo tanto, el costo total en la compra es $4.00 pesos.
