Answer:
Sue collected 1/2 bags of clothes.
Step-by-step explanation:
Fractions
Let's solve the problem from end to beginning.
Martin collected 2 1/2 bags of clothes for a clothing drive. This mixed fraction can be expressed as:
[tex]2\frac{1}{2}= 2+\frac{1}{2}=\frac{5}{2}[/tex]
Sue collected 1/5 as many clothes as Martin did. This means she collected:
[tex]\frac{1}{5}\cdot \frac{5}{2}[/tex]
Multiplying:
[tex]\frac{1}{5}\cdot \frac{5}{2}=\frac{1}{2}[/tex]
Sue collected 1/2 bags of clothes.

3x - 17 = 2x + 35
Please help
Answer:
[tex]x = 52[/tex]
Step-by-step explanation:
We have the following equation:
[tex]3x -17=2x+35[/tex]
First we simplify the numbers.
[tex]3x -17+17=2x+35+17[/tex]
[tex]3x=2x+52[/tex]
[tex]3x-2x=2x-2x+52[/tex]
[tex]x=52[/tex]
Answer:
x = 52
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define equation
3x - 17 = 2x + 35
Step 2: Solve for x
Subtract 2x on both sides: x - 17 = 35Add 17 to both sides: x = 52Step 3: Check
Plug in x to verify it's a solution.
Substitute: 3(52) - 17 = 2(52) + 35Multiply: 156 - 17 = 104 + 35Subtract/Add: 139 = 139¿Cómo se resuelve este problema? Con explicacion por favor.

Find a 95% confidence interval for the true population proportion.
In a survey of 765 employees of a large company, 30% said that they had high job satisfaction.
Answer:
The 95% confidence interval for the true population proportion is (0.27, 0.33).
Step-by-step explanation:
The (1 - α)% confidence interval for population proportion of is:
[tex]CI=\hat p \pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
The information given is:
[tex]\hat p=0.30\\n=765\\\text{Confidence level}=95\%[/tex]
The critical value of z for 95% confidence level is, 1.96.
Compute the 95% confidence interval for the true population proportion as follows:
[tex]CI=\hat p \pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
[tex]=0.30\pm 1.96\times\sqrt{\frac{0.30(1-0.30)}{765}}\\\\=0.30\pm 0.0325\\\\=(0.2675, 0.3325)\\\\\approx (0.27, 0.33)[/tex]
Thus, the 95% confidence interval for the true population proportion is (0.27, 0.33).

A motorcycle make 100 revelation in moving a distance of 220m find the diameter of the wheel
Answer:
Step-by-step explanation:
If it goes 220 meters and has made 100 revolutions that means that each revolution is 220 meters / 100 = 2.2 meters.
That's the same thing as saying that the wheel has a circumference of 2.2 meters.
Circumference = 2*pi * r = pi * d
2 = pi * d
2 = 3.14 * d
2/3.14 = d
d = 0.6369 meters

Step-by-step explanation:
Fruit flies, like almost all other living organisms, have built-in circadian rhythms that keep time even in the absence of external stimuli. Several genes have been shown to be involved in internal timekeeping, including per (period) and tim (timeless). Mutations in these two genes, and in other genes, disrupt timekeeping abilities. Interestingly, these genes have also been shown to be involved in other time-related behavior, such as the frequency of wingbeats in male courtship behaviors. Individuals that carry particular mutations of per and tim have been shown to copulate for longer than individuals that have neither mutation. But do these two mutations affect copulation time in similar ways? The following table summarizes some data on the duration of copulation for flies that carry either the tim mutation or the per mutation (Beaver and Giebultowicz 2004).
Mutation Mean copulation duration (min) Standard deviation of copulation duration Sample size, n
per 17.5 3.37 14
tim 19.9 2.47 17
Assume that the copulation time data are normally distributed. Do tim and per mutations lead to different mean copulation durations? Determine the absolute value of the test statistic for the appropriate test.
Answer:
The decision Rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to states that tim and per's mutations lead to different mean copulation duration.
The test statistics is [tex]z =-2.2187[/tex]
Step-by-step explanation:
From the question we are told that
The Mutation Mean copulation duration is for per [tex]\= x_1 = 17.5[/tex]
The Mutation Mean copulation duration is for tim [tex]\= x_2 = 19.9[/tex]
The Mutation Standard deviation copulation duration for is per [tex]s _1 = 3.37[/tex]
The Mutation Standard deviation copulation duration for is tim [tex]s _2 = 2.47[/tex]
The sample size for per is [tex]n_1 = 14[/tex]
The sample size for tim is [tex]n_2 = 17[/tex]
The null hypothesis is [tex]H_o : \mu_1 = \mu_2[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 \ne \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_2} } }[/tex]
=> [tex]z = \frac{17.5 - 19.9 }{ \sqrt{\frac{3.37^2 }{14} + \frac{2.47^2 }{17} } }[/tex]
=> [tex]z =-2.2187[/tex]
From the z table the area under the normal curve to the left corresponding to -2.2187 is
[tex]P(Z < -2.2187) = 0.013254[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z <-2.2187 )[/tex]
=> [tex]p-value = 2 * 0.013254[/tex]
=> [tex]p-value = 0.02651[/tex]
Let assume that the level of significance is [tex]\alpha = 0.05[/tex]
So
From the value obtained we see that [tex]p-value < \alpha[/tex] hence
The decision Rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to states that tim and per's mutations lead to different mean copulation duration.
