Answer:
B) 10^0
Step-by-step explanation:
Well when dividing an exponent, you subtract the exponents but keep the base, this is the rule of exponents.
So in this case you got 10^-3/10^-3
SO you subtract the wo exponents and don’t forget to keep the sign
-3-(-3)
or -3+3
so 0
so final answer is 10^0
Answer:
The correct answer is B. 10(0).
Step-by-step explanation:
10^3 =
10 x 10 x 10 =
1,000
-------------------------
1,000 ÷ 1,000 = 1
10(0) = 1
Therefore, the correct answer is B. 10(0).
Hope this helps! :D

Triangle UVW is formed by the three squares G, H, and I:
A right triangle UVW is shown. On the side UV of this triangle is a square. Inside the square is written Square G, Area equal to 81 square units. On the side VW of this triangle is another square. Inside the square is written Square H, Area equal to 144 square units. On the side UW of this triangle is another square. Inside the square is written Square I, Area equal to 225 square units.
Which statement best explains the relationship between the sides of triangle UVW?
UV + VW = UW, because 81 + 144 = 225
(UV)2 + (VW)2 = (UW)2, because 152 + 92 = 122
(UV)2 + (VW)2 = (UW)2, because 81 + 144 = 225
UV + VW = UW, because 152 + 92 = 122
Answers
Answer:
The correct answer would be C- (UV)2 + (VW)2 = (UW)2, because 81 + 144 = 225
-Thank you
Answer:
C. (UV)2 + (VW)2 = (UW)2, because 81 + 144 = 225
Step-by-step explanation:
81 + 114 = 225
225 = 225

The equation 3y + 1 = 3y + 1 has all real numbers as solutions becasuse 0 = 0 true for all real numbers option (D) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The first equation:
3y = 3y + 1
0 = 1 (false)
The second equation:
3y = 3
y = 1 (one real solution)
The third equation:
3y = 0
y = 0 (one real solution)
The fourth equation:
3y + 1 = 3y + 1
0 = 0 (infinitely solution)
Thus, the equation 3y + 1 = 3y + 1 has all real numbers as solutions becasuse 0 = 0 true for all real numbers option (D) is correct.

Complete Question
A researcher posed a null hypothesis that there was no significant difference between boys and girls on a standard memory test. He randomly sampled 40 girls and 40 boys in a community and gave them the standard memory test. The mean score for girls was 68 and the standard deviation of mean was 5.0. The mean score for boys was 66 and the standard deviation of mean was 5.0. What is the p-value and your conclusion at alpha 0.05
Answer:
The p-value is [tex]p-value =0.073614[/tex]
The conclusion is
There is sufficient evidence to support the claim that there was no significant difference between boys and girls on a standard memory test
Step-by-step explanation:
From the question we are told that
The sample size of boys and girls is [tex]n_1= n_2 = n = 40[/tex]
The standard deviation is [tex]s_1= s_2 = s = 5[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The sample mean for boys is [tex]\= x_1 =66[/tex]
The null hypothesis is [tex]H_o : \mu_1 = \mu_2[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 < \mu_2[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\= x_1 - \= x_2 }{ \sqrt{\frac{s_1 ^2 }{n_1} + \frac{s_2 ^2 }{n_1} } }[/tex]
=> [tex]z = \frac{66 -68 }{ \sqrt{\frac{5^2 }{40} + \frac{5 ^2 }{40} } }[/tex]
=> [tex]z = -1.789[/tex]
From the z table the area under the normal curve to the left corresponding to -1,789 is
[tex]P(Z < -.1789 ) = 0.036807[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 P(Z < -.1789 )[/tex]
=> [tex]p-value = 2 * 0.036807[/tex]
=> [tex]p-value =0.073614[/tex]
From the values obtained we see that [tex]p-value < \alpha[/tex] hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is sufficient evidence to support the claim that there was no significant difference between boys and girls on a standard memory test
The cafeteria offers two snack options as shown in the table. Out of 18
students, 8 students choose Option B and the rest choose Option A. If the
total cost of option A is the same as the option B, what is the price of a
carton of milk?”
Answers
Answer:69,420
Step-by-step explanation:
9+10=21
The price of a carton of milk is $1.00
The given parameters are:
Number of students, n = 18Option A = 8Since 8 chose option A, it means that 10 would choose option B
So, the equation that represents when both price are equal is:
[tex]8(2x + 0.5) = 10(x + 1)[/tex]
Where
2x + 0.5 represents the unit price of option A
x + 1 represents the unit price of option B
Open the brackets
[tex]16x + 4 = 10x + 10[/tex]
Collect like terms
[tex]16x - 10x = 10 - 4[/tex]
Evaluate the like terms
[tex]6x = 6[/tex]
Divide
[tex]x = 1[/tex]
Hence, the price of a carton of milk is $1.00
