Please help me solve x and z

Answers

Answer: Z = 107 as the opposite angles are equal. Then to find x, z is on the same line as (10x+3) so,

107+10x+3=180°

10x+3= 180-107

10x+3= 73°

now,

10x= 73-3 = 70

x= 70/10

x= 7

Hence z= 107 and x=7

pls mark brainliest

Answer:

$x=7\nz=107$

Step-by-step explanation:

First we can solve for x,

107 and 10x+3 is straight line which is 180 so make an equation:

$107+(10x+3)=180$

$10x +107+3=180$

$10x+110=180$

$10x=180-110$

$10x=70$

$x=70/10$

$x=7$

10(7) + 3 = 73

{CHECK: 107 + 10(7) + 3 = 180}

Now, let's find the value of z

As we have the value of x it will be easy to find z by forming an equation:

$z+73=180$

$z=180-73$

$z=107$

{CHECK: 107 + 73 = 180}

What number goes in cell A?

Answers

Answer:

Cell A = 15

Step-by-step explanation:

If 6 spring rolls will serve 3 people, let x be the number of people 30 spring rolls will serve.

Thus,

6 spring rolls = 3 people

30 spring rolls = x

Cross multiply

6*x = 3*30

6x = 90

Divide both sides by 6

6x/6 = 90/6

x = 15

30 spring rolls will serve 15 people.

Final answer:

The question is asking for a proportion based on the initial data. The correct number for cell A is 15, calculated by dividing the total number of spring rolls by the ratio of spring rolls per person.

Explanation:

This question deals with proportions. Proportions look at the relationship between two pairs of numbers. If 6 spring rolls can serve 3 people, that means each person will get 2 spring rolls. This forms a ratio of 2:1, meaning each person gets 2 spring rolls.

Applying this ratio to 30 spring rolls, we would do the following calculation: 30 spring rolls / 2 spring rolls per person = 15 people. Therefore, cell A in the table should be filled with the number 15.

#SPJ3

A study published in 1993 found that babies born at different times of the year may develop the ability to crawl at different ages! The author of the study suggested that these differences may be related to the temperature at the time the infant is 6 months old. (Benson and Janette, Infant Behavior and Development [1993]. The study found that 32 babies born in January crawled at an average age of 29.84 weeks, with a standard deviation of 7.08 weeks. Among 21 July babies, crawling ages averaged 33.64 weeks, with a standard deviation of 6.91 weeks. Is this difference significant?

Answers

Answer:

$t=\frac{(29.84-33.64)-0}{\sqrt{(7.08^2)/(32)+(6.91^2)/(21)}}}=-1.939$

$p_v =2*P(t_(51)<-1.939)=0.0580$

Comparing the p value with the significance assumed $\alpha=0.01$ we see that $p_v>\alpha$ so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and the difference between the two groups is NOT significantly different at 1% of significance.

Step-by-step explanation:

Data given

$\bar X_(1)=29.84$ represent the mean for sample January

$\bar X_(2)=33.64$ represent the mean for sample July

$s_(1)=7.08$ represent the sample standard deviation for 1

$s_(2)=6.91$ represent the sample standard deviation for 2

$n_(1)=32$ sample size for the group 2

$n_(2)=21$ sample size for the group 2

$\alpha=0.01$ Significance level provided

t would represent the statistic (variable of interest)

Concepts and formulas to use

We need to conduct a hypothesis in order to check if the difference in the population means, the system of hypothesis would be:

Null hypothesis: $\mu_(1)-\mu_(2)=0$

Alternative hypothesis: $\mu_(1) - \mu_(2)\neq 0$

We don't have the population standard deviation's, so for this case is better apply a t test to compare means, and the statistic is given by:

$t=\frac{(\bar X_(1)-\bar X_(2))-\Delta}{\sqrt{(\sigma^2_(1))/(n_(1))+(\sigma^2_(2))/(n_(2))}}$ (1)

And the degrees of freedom are given by $df=n_1 +n_2 -2=32+21-2=51$

t-test: Is used to compare group means. Is one of the most common tests and is used to determine whether the means of two groups are equal to each other.

With the info given we can replace in formula (1) like this:

$t=\frac{(29.84-33.64)-0}{\sqrt{(7.08^2)/(32)+(6.91^2)/(21)}}}=-1.939$

P value

Since is a bilateral test the p value would be:

$p_v =2*P(t_(51)<-1.939)=0.0580$
