How to find the pounds of ham she has left?Ms.D bought [tex]8\frac{1}{2}[/tex] pounds of ham from Excellente Hambaked Shop. She gave [tex]1\frac{3}{4}[/tex] pounds of ham to Mr.Chavir. The number of pounds of ham she has left can be calculated as follows:
Hence, the amount of hams in pounds she has left is the difference between what she had and the amount of pounds of hams she gave to Mr Chavir.
Therefore,
Amount bought by Ms.D = [tex]8\frac{1}{2}[/tex] pounds
Amount given to Mr.Chavir. = [tex]1\frac{3}{4}[/tex] pounds
Therefore,
Amount of she has left = [tex]8\frac{1}{2}[/tex] - [tex]1\frac{3}{4}[/tex]
Amount of she has left = [tex]\frac{17}{2} - \frac{7}{4}[/tex]
Amount of she has left = [tex]\frac{34-7}{4}[/tex]
Amount of she has left = [tex]\frac{27}{4}[/tex]

What is the length of side bc of the triangle? enter your answer in the box. Units.
The length of the side BC Iis equal to 28 units which we get by using congruency.
What is congruency?In other words, if the lengths of the sides and angles are the same for two shapes, they are congruent (the same in shape and size). When two triangles are congruent, it is frequently useful to know.
* In triangle ABC
∵ Angles B and C comes to be congruent
∴ m∠B = m∠C
* In any triangle if two angles are equal in measure, then the triangle is isosceles means the two sides which opposite to the congruent angles are equal in length
∴ AB = AC
∵ AB = 4x - 7
∵ AC = 2x + 7
∴ 4x - 7 = 2x + 7 ⇒ collect same terms
∴ 4x - 2x = 7 + 7
∴ 2x = 14 ⇒ divide both the sides by 2
∴ x = 14 ÷ 2 = 7
* Now we can find the length of side BC
∵ The length of side BC = 4x ⇒ substituting the value of x
∴ The length of side BC = 4 × 7 = 28 units

What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Z is the incenter of WXY.
m∠WYX = 86
This means,
m∠WYZ = m∠XYZ = x
m∠WYZ + m∠XYZ = m∠WYX
2x = 86
x = 43
m∠WXZ = 33.
m∠WXZ = m∠WXY
Now,
The triangle WXY.
m∠YWX + m∠WXY + m∠WYX = 180
m∠YWX + 33 + 86 = 180
m∠YWX = 180 - 119
m∠YWX = 61
m∠ZWX = 61/2 = 30.5

question if x, y, and z are integers and xy z is an odd integer, is x an even integer? (1) xy xz is an even integer. (2) y xz is an odd integer.
xy + xz is an even integer & x is even and y + xz is an odd integer & either (x-1) is even or (y-z) is even .
1. xy + xz is an even integer - SUFFICIENT
Given:
xy + z is odd ...(i)
xy + xz is even ...(ii)
subtracting (ii) from (i)

a test of which hypothesis is most important when deciding whether to use a simple linear regression model to predict y from x?
The most important measure used in regression diagnostics is the simple residual.
What is linear rigression?
In statistics, a scalar response and one or more explanatory factors are modeled using a linear approach called linear regression. Simple linear regression is used when there is only one explanatory variable; multiple linear regression is used when there are numerous explanatory variables.
Hypothesis testing is used to confirm if our beta coefficients are significant in a linear regression model. Every time we run the linear regression model, we test if the line is significant or not by checking if the coefficient is significant.
If there is a significant linear relationship between the independent variable X and the dependent variable Y, the slope will not equal zero.
The null hypothesis states that the slope is equal to zero, and the alternative hypothesis states that the slope is not equal to zero.
The most important measure used in regression diagnostics is the simple residual (e). This is the difference between each observed and predicted value of Y.

special industrial battery must have a life of at least 400 hours. a hypothesis test is to be conducted with a 0.02 level of significance. if the batteries from a particular production run have an actual mean use life of 391 hours, the production manager wants a sampling procedure that only 10% of the time would show erroneously that the batch is acceptable. what sample size is recommended for the hypothesis test? use 45 hours as an estimate of the population standard deviation. (round your answer up to the nearest integer.)
488601 is the sample size recommended for the hypothesis test.
Given,
The life of the battery = 400 hours
Significance level = 0.02
Mean = 391 hours
The production manager needs a sampling technique that would incorrectly indicate that the batch is acceptable only 10% of the time.
We have to find the sample size recommended for the hypothesis test;
Here,
Margin of error E = Z(α/2) × (σ/n²)
From this equation we get n as
n = (z × σ /E)^2
α = 0.02
From the standard normal table value we get
z(α/2) = 2.33
σ = 30
E= 0.1
Therefore,
n =(2.33*30/0.1)^2
n =488601
